Now more and more people are wearing Fake oakleys frogskins sunglasses cheap for sale glasses for children, excluding certain congenital myopia, most of them with an eye to improper, kids watching TV, playing video games, and a heavy burden of homework, which all contribute to the major causes of myopia. Myopia and enjoy after a qualifying pair of glasses is very important, optical shops but now many are professional enough glasses pass rate was not high. Lot of myopia in children do not understand may have myopia also did not tell them, if you find that what their children watch squinting, like squinting to see things get, there is myopia, parents should take their children to the regular hospital checks in a timely manner with glasses. Eyeglasses are not available for doing whatever one can be a Deputy, if the specs don't fit, wears not only uncomfortable and may also accelerate the development of myopia. When children have myopia, first to the regular hospital checks done, barring any vision loss due to disease. Children enjoy mirror best is bulk Hitomi again optometry, such to accurate of detection children of vision situation, due to children age small, individual differences sexual many, plus glasses regulation sexual comparison strong, if not bulk big pupil optometry may will makes detection results not accurate, some children Cheap Oakleys Radar Sunglasses Discount may also will appeared is not bulk Hitomi check for myopia, and bulk Hitomi zhihou detection is for hyperopia of phenomenon. Mydriasis can also detect myopia in children is true myopia or myopia is false, if you disappear after Mydriasis description for pseudo myopia, if after Mydriasis degrees still exist as true myopia. If verification of degrees to disappear, to false myopia, we recommend attention to eye health, prevent eye fatigue, in the case of intraocular pressure is not high, before going to bed can be bit of a tropic amide compound eye lift adjusting tension. Eyeglasses are not simple things with glasses must be accurately, astigmatic axis, horizontal axis, pupillary distance accurately, will adjust the number of glasses to let kids wear for 15 minutes to see if they had headaches, dizziness or other abnormal feeling and to see whether they tilt, if this is the case you should continue to adapt. Go to regular hospitals eyeglasses can also detect the presence of child with amblyopia, amblyopia is an eye there is no organic disease the monocular or binocular vision glasses correct still amounted to less than 0. 9 per cent of the children. Amblyopia is not only poor vision, and no stereo vision capability. Best treatment for preschool, at the age of 8 in the treatment of Cheap Tiffany and Co Necklace Jewelry Outlet with best results, to 12 years of treatment effect is very poor. So when the positive treatment of amblyopia is detected.
Glasses do not apply after there are three possibilities: Optometry inaccurate results or Cheap Oakleys Radar Sunglasses Discount glasses prescription without conversion; II, lens installation is not appropriate; Third, the existence of certain optical defects of the lens. 1) result optometry and glasses prescription Optometry method is divided into two kinds of subjective and objective. Subjective refraction appropriate for simple refractive, and objective view on all refractive error conditions are suitable. Objective view agent before using the ciliary muscle paralysis, which can cause eye fatigue the muscles to rest, role of ciliary muscle disappeared, Mydriasis, recessive refractive errors become dominant, laid the Foundation for us to arrive at a real result. Especially in patients who do not cooperate, we can directly control their refractive conditions. The optometry inaccurate results due, on the one hand the right way, on the ciliary muscle paralysis agents is not used, the subjective objective of Optometry optometry, Hitomi optometry the Mydriatic refractometry, such as objective refraction results for -4.5DS-1.00DCx180=5.0, subjective refraction results likely to be -5.0DS=5.0, by the opticians, patient discomfort is inevitable. Glasses prescription is not exactly the same as the view results, it must be the latter on the basis of the appropriate "processing", otherwise the patient may not be able to endure. Anisometropia, difference in degrees to control 3.0D, so as to avoid his eyes ranging eye astigmatism axis converted to Parallels or symmetrical, so as not to lead to distortion; lens degree is higher due to lower, while increasing spherical mirror; high hyperopia glasses to reduce the degree for the first time. 2) lens installation The tilt of the lens. Eye looking down many opportunities, especially when you're tall and read eye in patients with, and perpendicular to the axis of the lens, there must be a certain degree of tilt, usually 10-150. Distance between lens and cornea. For determining the effectiveness of Cheap Tiffany and Co Necklace Jewelry Outlet lenses and retinal image size plays a very important role. Theory of 15.7mm, 13-14mm, without touching the eyelashes. Because the lens away from the cornea or near or far, can lead to retinal image to zoom in or out, when the difference in eye diopter is large, the eyes cannot blend cause discomfort. Improper handling of the optical center of the lens and polarizing, Every deputy has to determine the optical center of the lens, optical Center, and install it properly, otherwise the light entering the eye deviation. 10.0D spherical lenses, optical Center offset 1mm, 1 Prism effect caused by poor inspection interference occurs. Centre for optical and geometric center and do not confuse. In actual work in the, we sometimes will intends to let optical Center deviated from Geometry Center, as with glasses to for not symmetric of faces; lenses due to itself weight or nasal bone low led to glasses fell and will optical Center up offset,, is to better to avoid polarizing heart of occurred, also has artificial to polarizing heart installed sense also this, as near with glasses; correction implicit strabismus or overcome collection force insufficient or had strong Shi. Therefore, heart is light or polarized, pros and cons isn't set in stone, but handled properly there will be trouble. Pupillary distance measurement determination is incorrect or correct lens installation error, Prism effect may also occur, not repeat them here. 3) lenses is optical defects This problem cannot be avoided, such as a lens or two refractive distortion caused by cataract lenses, such as narrowing of the Visual field, having ruled out other factors still cannot be completely eliminated, but to let patients get used to. Some can be reduced and even eliminated, if oblique astigmatism question, spherical aberrations, such as zoom, which demands for installation and selection of lenses. It is well known that in order to make eyeball in all aspects of vision are clear to see, we should choose a week depending on the type of lens (base arc 1.25D); the most oblique astigmatism, you choose to Crescent-shaped lenses (base arc 6.0D); when the lens is being installed requires concave near the eye forever, to eliminate the spherical aberration, and ranges in order to prevent, also can choose lenses. In practice, the author has such experience, many after the patients switched to another type of lens, Visual disturbance disappear immediately, although the targets exactly the same two pairs of Fake oakleys frogskins sunglasses cheap for sale eyeglasses, so selecting the right model, reducing optical defects of the lens itself to eliminating opticians do not apply after is also important.
First of all, to go to hospital or formal optometry Cheap Oakleys Frogskins Sunglasses Outlet glasses shop, free or very cheap price. Is the optical shop, not soft, finished by the way has also been equipped with sunglasses, it won't have to look down. According to optometry's situation, some people still not suitable for glasses online, such as: 1, the eye is a very heterogeneous or defective, such as PD, 8CM; strabismus severely cross-eyed ... You should be a normal, ignore this point. 2, vision of instability, such as 200 today, after a few days on the 300, so your glasses arrived, no, you should not be so bad, please ignore this. 3, eyes a lot worse, like a 10,001 x 200 + 4, astigmatism with myopia 5, high myopia, for example, more than 1000 degrees 3, 4, 5, mainly online opticians have no physical, with the glasses a bit difficult, and put on new glasses could not adapt to needs service. If you go to the store is not very convenient. -Choosing lenses, I learn about optical lens is quite. First, the brand or something please ignore, if you think branding is important to you, or go to the store. Second, many of the tiffany and co outlet features not to be hoodwinked, UV-resistant, radiation resistance, are bragging. Hardened and coated a bit, but there's no need to spend 1-2, with one Deputy, was a better choice. The curvature of the lens, 1.56, 1.67, or something like that, the higher the number the thinner, more expensive of course. If your degree is relatively high, super thin, still too thick you can choose non-spherical (and more expensive), this not to brag, but if 6, 700 degrees of myopia, not too necessary. Then there is the color, lenses have silver halide, increases as the intensity of the Sun, the lens darker. Personally, I think is not too necessary, should guard against the Suns in the summer and enjoy additional clamps on the line. Certainly fresh but equipped with a pair of play is good. Personal recommendations, curvature, 1.56, green-coated film, online opticians was traded in 501 Selected frames, it's hard Frame look ugly, opinions differ, so it's hard to say why. But spec is worth about, it doesn't look like everyone's head, still have to think about it. Mirrors on the leg is a set of numbers, such as 18-135, 52, identified as lens width 52MM wide leg 18MM mirror long nose 135MM, depending on your size available. Similarly, the brand is not considered, specializes in manufacture of all brands in the world. And finally price. Many shops frames are sent send stuff is not bad, if you don't like it, pick, in short, all the specs, and normally does not exceed 100. Merchant materials cost less than 30, the processing will take about half an hour, and also give you glasses case, cleaning the Discount Oakleys Flak Jacket Sunglasses Cheap glasses, so the price is also reasonable.
Routine care should be aware of the following issues 1, pick to carefully wash your hands before you wear Cheap Tiffany and Co Necklace Jewelry Outlet lenses, regular nails; Type 2, not wearing ordinary day wearing contact lenses to bed for the night; 3 strictly in accordance with the provisions of regular replacement of contact lenses wear cycle, not wearing expired lenses; 4 strictly in accordance with the procedure provided for nursing, immersion lens, immersion time shall be not less than 4 hours; 5, do not use running water, saliva, household cleaning supplies, soaps or shampoos to clean lenses; 6 is not available used care solution again handling lenses; 7, please keep the CAP closed when not using the solution, do not put bottle in contact with any article, to avoid contamination; 8, care solution suitable for heating use, do not care solution to mix with other brand; 9, if the care allergy, do not use any liquid constituents; 10 non-special eye drops for contact lenses, not to drip water; 11, if you are suffering from trachoma, eye and other eye diseases, please consult checking recovered at the original mirrors who wear contact lenses; 12, cleaning the Fake oakleys frogskins sunglasses cheap for sale mirror box once a week, once every three months, replacing the mirror box to avoid bacteria; 13, if there is a red eye, eye pain, photophobia tears, increased secretions, blurred vision and other circumstances, to stop immediately for medical treatment; 14, after washing hands with antiseptic washing agent ingredients to use, you should rinse with large flows of water to avoid irritation to the eyes, or with a mild irritation of care rinse lens fingers; 15, to refrain from working with the outdated solution, run-out protein-removing care solution bottle after 120 days if not used up, please stop using; the lens when not wearing long, remains in tightening the lid with a fresh run Ming in the mirror box protein-removing care solution for 30 days. Before you use it again using run-out protein-removing care solution washed before being worn; 16, by far the most scientific method of cleaning is clean lens with clean hands. Available in the market to clean lenses that are often invisible to the naked eye damage, damaged lens surface not smooth, prone to wearing ill and a corneal abrasion. So the wearer is not recommended to use cleaner. 17, wearing contact lenses, to stay away from irritating substances, vapours, smoke, including cosmetics, hair spray and other chemical products, direct or indirect contact with contaminated lenses cause eye irritation. Especially spicy food, once for stimulation of eye contact is very strong. Wearing eyeglasses make sure to thoroughly wash your hands before, once exposure to irritants must remove eyeglasses repeated thorough cleaning of contact lenses. If you still have feelings to professional optical shop for eye examination; 18, the right cosmetic procedures: wear lenses and then makeup, remove the lens first and then makeup. If lens accidentally cosmetics, remove the liquid cleaning lenses and care; 19, pick mirrors to avoid too much force to prevent adhesion of lens. If sticking occurs, do not force tears. Lenses should be placed palms, drip a few drops of solution, and gently rub until it separated from adhesions. In addition, if picked before the mirror contact lens drops of lubricating fluid, lenses are easier to pick up without adhesion; 20, when you store contact lenses, lens fully immersed in solution. Once dehydration can cause lens edges (edge damage), so wear may cause eye irritation. If you find that edge of the lens when it is not round, immediately immerse the Cheap Oakleys Radar Sunglasses Discount lenses in the solution until the lens back together again check for broken lenses, if no damage can continue to wear. Should they run into problems please go to the opticians Office for review.

Starting from the movie avatar, 3D movies often shown Cheap Oakleys Frogskins Sunglasses Outlet has become a popular word in these two years, being sought after not only 3D movies, TV production companies also took the ride, will soon launch watch Stereo 3D televisions can be achieved. Almost all brands will abandon their 3D TVs are placed in a prominent position, many brands have played ads of buy 3D TVs get 3D glasses, 3D TV has become the main selling product at the Mall. Appliance store sales personnel, with 3D enabled TV from that began two years ago, first listed due to high visibility and low prices, sales are not optimistic, however, since the movie avatar, transformers, the Titanic, started after the release, 3D TV began to quickly access to the ordinary people. Big-screen 3D TVs by consumers of all ages, of which 46 inch models have been widely welcomed by the public, and 55-inch big screen TV sales continue to rise. Watch 3D TV must be equipped with 3D glasses It is understood that the sales of 3D TVs on the market today, consumers need for professional 3D glasses to enjoy the stereo image, meaning buying 3D TVs also have to buy 3D glasses, so what do consumers think about this? How to choose it? Currently, 3D TVs on the market can be divided into active shutter and polarized in two classes, correspond to the 3D glasses is also divided into two categories, his appearance is ordinary sunglasses polarized 3D glasses, we at the cinema watching a 3D movie for just such tiffany and co outlet glasses. This switch when using, and requires active shutter rechargeable glasses are currently using this technology to TV companies than adopting polarized 3D technologies. Some consumers who do not choose a 3D TV and enjoy 3D effects without 3D glasses have a great relationship. Reporters in the electrical market understands that a pair of polarized glasses less is more than more than 300 thousand, the price is more expensive active shutter glasses, a lot of consumers taking into account the price of selected online purchases. In shopping malls and pricey 3D glasses in buying just a few dozens of online shopping platform, so how can the quality of these glasses, can achieve the 3D TVs expected results? Various 3D glasses from a Yuan to tens of thousands of everything, in who shop in found has a paragraph material for red blue upscale resin lenses of 3D glasses, price for 5 Yuan, sales records displayed from April 1 to yesterday total sold has 434 pieces, in evaluation details in reporter see, are has wearing while on some dizzy, and heavy shadow is badly almost see not out 3D effect of words. When consumers buy to try to personally wear, watch videos and 3D videos, selected after comparison. Moreover, while wearing 3D glasses will have strong visual impact, but should not be worn for a long time, and because stereo screen visual functions varies by individual, not all people are fit to wear 3D glasses. Long-term use of 3D Discount Oakleys Flak Jacket Sunglasses Cheap Glasses are easy to cause visual fatigue, causing eye swelling, severe can cause dizziness, nausea, and vomiting and other symptoms, if feeling unwell should be carried out immediately to the regular hospital checks.

Hold with both hands on both sides of the temple Abstract cheek along a direction parallel to wear. If you pick to wear with one hand around the Cheap Tiffany and Co Necklace Jewelry Outlet frame will destroy the balance and cause deformation.
2, the left should start folding frame
Most of the frames are started by the left leg folded lens design, so if the first off right temple, it is likely to cause deformation of the frame.
3, rotation method
If it is a temporary place glasses, set of glasses convex upward. If placed downward convex glasses, the lenses will wear flowers.
4, wipe lenses way
Use clean special lens cleaning cloth, wipe the attention sure to hold the mirror hand side of the frame side of the wire and gently wipe the lens. Avoid overexertion injuries caused by frame or lens.
5, the lens or dirt James Gray
Easy to wear flowers dry rub the lens, it is recommended rinse water and then dry with a paper towel after special glasses cloth. When the Cheap Oakleys Radar Sunglasses Discount lens is dirty, it is recommended to use low concentrations of a mild detergent, then rinse dry.
6, please use the glasses case
When not wearing glasses, use glasses cloth glasses box placed. When you save Avoid contact with insect repellent, toilet articles, cosmetics, hair sprays, medicines and other corrosive materials, otherwise it will cause the lens, frames degradation, deterioration, discoloration.
7, the deformation of glasses
Frame deformed nose or ears will burden the lens is also easy to loose. Recommend regular adjustments to shaping specialty.
8, do not use during intense exercise
Resin lenses have broken a strong impact may easily cause eye and facial injuries, is not recommended for use in intense exercise.
9 Do not use lens wear flowers
Not recommended lens cases have occurred scratches, stains, cracks, etc., otherwise they will cause the light to see things clear colored loose, causing decreased vision.
10, do not look directly sunglasses
Even if there are differences in the color shade of the Fake oakleys frogskins sunglasses cheap for sale lens, do not look directly at the sun or strong light, otherwise it will hurt the eyes.
Myopia in children because the required spectacle vision correction. Many parents want to use Orthotics as clearly as you can, in fact, is not conducive to the child's visual development. Clinically, doctors generally myopic children's Orthotics to 1.0, and even sometimes needs and habits according to the child's eye, such as child seats in front, at close range with an eye more, their myopia suitable distribution low, Dai Jing vision then the children may have amounted to less than 1.0. Therefore, children Discount Oakleys Flak Jacket Sunglasses Cheap glasses may not need vision correction to 1.0, should take into consideration their demand for daily eye, wearing comfort, and other factors. Generally speaking, kids glasses after you wear glasses at the far and near, as it makes your eyes adjust and coordinated collection capacity, could not be easily fatigued when reading. For some children with low myopia, as up to 200 degrees, you can also consider ongoing close eye without glasses, so can be reduced to a certain extent, the eyes focused enough, there might be some delay the effects of myopia development. But at the same time taking into account specific situations such as child's binocular vision, such as children with insufficient external oblique or implicit collection, regardless of it long or short are required to wear goggles. Children require periodic review after wearing glasses, myopia increase more, Dai Jing, poor eyesight and did not meet the needs of daily life easily with an eye; you need timely replacement of glasses. Children wearing Visual acuity less than 0.6 will consider replacing the glasses will of course need to demand according to the child's eye, binocular vision conditions, such as specific elements may be. After replacing the Cheap Oakleys Frogskins Sunglasses Outlet glasses, you can read, write, and so when the eyes at close range with low powered glasses, to a certain extent alleviate the problem of insufficient eye focusing at close range, controlling myopia progression may also have helped. In the growth and development of myopia in children is usually 50~100 per annum, the vast majority of children's nearsightedness in adulthood will gradually cease to grow. Clinical study found that rapid growth and development of children in the 10~15 period, the myopic growth rate is faster, baby, of course, this may be related to that stage reduced heavy study load, outdoor activities, and so on. Youths wearing OK microscopy can significantly slow the progress of myopia. Age adolescents than wearing conventional glasses, wearing OK mirrors slowing myopia development about half of those, or even some wearing 3 years later in children with only 25 degrees of myopia, a handful of kids wearing only deepened the 150 degrees of myopia after 10 years. A Hong Kong study also found that continuous wear OK mirror 3 years; their eyeballs grow into wearing glasses teen half his age, degree of myopia development for the latter half. Children wear glasses for far closer eye; there may be a problem of insufficient focus, which would have some catalytic role for development of myopia. Thus, progressive Multifocal Lens tries to apply to children and teenagers. It works by reducing the degree of myopia when, to reduce the problem of insufficient eye focused short. Lots of studies have found that wearing progressive multi-focal lenses have a delaying effect on myopia development in some children. But wearing such glasses you need to fully take into account children wearing habits, reading and writing position, binocular vision. For example, after wearing progressive multi-focal glasses can pass below the low part, reading and writing, otherwise would not play the role of such glasses; or the child is accompanied by a certain degree of latent squint, got no business wearing such glasses outside the otherwise continuous wear such tiffany and co outlet glasses may exacerbate latent strabismus, or even lead to intermittent strabismus, which added attention to fatigue.
What are coated lenses? The Fake oakleys frogskins sunglasses cheap for sale lens surface is multi-layer antireflection coating to reduce specular reflection, increase transparency, ensure visual clarity, increase aesthetics and reduce red, ultraviolet damage to the eyes. Children's glasses should pay attention to what the problem is? When children glasses, generally choose resin lenses (light, safe, easy to break), but the surface is easy to scratch, so it is best to use plus dura resin lenses. When selected frame, generally based on the child's face to select the appropriate, safe, lightweight, durable frame ( generally Plate Frame ranks high ), but should pay attention to the length of the mounting brackets to increase frame stability, good general child move, so are accompanied by a chain hanging around her neck. Why measure the glasses IPD? IPD is intended to measure the optical center of the lens and binocular pupillary distance from consistent, so that patients wear comfortable, otherwise it will produce a prism effect, the patient will be visual fatigue, dizziness, nausea and other symptoms. Look at the past to wearing glasses, looking far off again a lot of trouble, what better way ? You can wear a pair of glasses, the main piece to look too far, while the lower part of the sub- sheet and visible close, but from the appearance of bifocals relatively funny, as far as the near field zone and obvious " beating " phenomenon, or with a gradient Cheap Tiffany and Co Necklace Jewelry Outlet lens, can all distances from far to near objects are clear, consistent vision and unparalleled " jump light " phenomenon of light microscopy. Mirror of how it is? Mirror of the material is added to the silver halide, silver decomposed under light stimulation with halogen, colored glass, and the light becomes weak, and combined into a silver halide color lighter. The process is reversible. Lenses can go on forever changed? Cannot. Because of this long-term reversible reaction lose some element of the lens with the ability to slow down lighting to reduce discoloration, it should be replaced periodically photochromic lenses, replace at least once every two years. What is the scientific method to select sunglasses? Choose sunglasses in addition to reducing the amount of light to achieve the purpose of shade and beautiful, the Cheap Oakleys Radar Sunglasses Discount most important thing is to prevent ultraviolet light. Ultraviolet radiation on the human eye what harm? Long-term excessive exposure to UV radiation may result in the conjunctiva, cornea and retina damage, a common eye disease UV are: pterygium, recurrent keratitis, cataracts, retinal degeneration.
Do you nearsighted? You have Discount Oakleys Flak Jacket Sunglasses Cheap sunglasses? With your eyeglasses, right? How can I enjoy a good pair of glasses? First of all, is to test the premise of maximum light and secondly want to feel more comfortable when wearing glasses, not oppressed. Generally speaking not very clear to consumers how to opticians, to enjoy a good pair of myopic glasses, should pay attention to the following aspects of the problem. 1, Jiao Du is the eye's refractive error level, the unit for the diopter, symbol is d. Myopia "-" said hyperopia mirrors with a "+". Such as "wearing is 300 degrees of myopia, meaning that the glasses shall be equipped with a pair of glasses is Jiao Du -3.00D. 2, the particular symbolic significance on eyeglass frames: frames showing "48 19 138", the "48" means that the lens is the size 48m m, "19" means space between two lens (that is, width of nose) is 19mm, "138" means mirror leg length, according to GB standard provisions of the tiffany and co outlet eyeglass frames, these flags are marked in the mirror inside of the legs. 3 when the prescription opticians, and optometry, its prescription, often marked with "r", "l", "d" letter, which means they are: the "r" means right eye lens; "l" means left eye lens, "d" indicates interpupillary distance. For example: -3.00DS/-1.00DS 90, meaning: the left eye lens; 300 degrees of myopia and astigmatism of 100 degrees, the lens axis level 90. Some people wearing nearsighted glasses after you just with a good feel not suited, walking a dizzy feeling. You might begin to wonder whether this time together with this pair of glasses. Wearing nearsighted glasses if you are dizzy or afraid to walk, people might think that this is a normal reaction, many also note the instructions on the glasses. In fact, it's bad specs. If wearing glasses Dizzy is axis of astigmatism is not allowed; particularly bright, see narrowing, is equipped with deep; nausea, vomiting is interpupillary distance is not allowed. This phenomenon appear in the low to medium myopia, worthy of a good pair of eyeglasses does not have this reaction. Judging a myopic glasses and enjoy how well it has a very simple "proximity" test. After wearing Cheap Oakleys Frogskins Sunglasses Outlet glasses, stretch fingers close to test, if the eyes look very natural, look at long distance, if it is natural, then the eyewear optometry is accurate.
Although many style of frames dazzling, but nothing more than a careful analysis of three basic types: square, round, oval. Generally oval face are suitable for all types of people; while square or round face the best choice for pear-shaped Cheap Tiffany and Co Necklace Jewelry Outlet frame ( prominent vertical line ); triangular face is usually round or oval frames wear.
Frame by different combinations of materials and processing system can be divided into:
A plastic frame: it is characterized by a light, easy processing, room temperature deformation, prices are generally lower.
2 metal frames: which is characterized by strong, light and beautiful, is currently the most commonly used frame.
3 hybrid frame (plate): namely, a blend of metal and plastic, with a metal frame that is rugged, and easily processed into various shapes.
5 No Frame: no frame, only the nose and the mirror angle coupled with higher.
Currently used by the lens material is divided into:
1 glass lenses: the refractive index of stability, good wear resistance, stable optical performance, but relatively heavy, and easy to break.
2 resin lenses (cr-39): Lightweight, safe, high transmittance, easy to break, but easy to scratch the surface wear.

To check the quality of Cheap Oakleys Radar Sunglasses Discount glasses, for ordinary consumers, there are several strong operational simple tests: 1, the test lens transparency and optical homogeneity: hand lens from the front 30 cm observe a far object from the lens, if the scene is clear, no distortion, and slowly no jumping moves, then the transparency of the lens and optical uniformity are better. 2, the test optical center displacement: On a large white cross with fine strokes, strokes should be clear and straight. Hand lens placed between the eye and the cross, with one stroke of the eye to observe the shape of a cross from the mirror if the mirror inside and outside of the stroke is not a line, you can move the lens, so that the cross with the outside mirror lens inside the cross stroke strokes in a line, then brush or a small fountain at the center point of the cross point of the lens, this point is the optical center. The latter two are to point out the optical center of the lens, the optical center is observed and compared with bilateral symmetry, and measure the distance between the centers of the pupil is consistent with the prescribed distance with a small ruler. If the lens bending crosses strokes, then there is a lens or optical density uneven stress problems. 3, measuring axial astigmatism lens: the lens rotates 30 cm above the cross pattern, visible lens cross appeared to move, to be inside and outside of the lens attached to the cross strokes graphic, graphics positively cross, this time the cylinder axis consistent and linear, then the Fake oakleys frogskins sunglasses cheap for sale lenses were repeatedly moved along a straight line, straight line which was observed when the lens moves and staggered out more in a straight line, this line is the astigmatic axis, moving straight alignment of the lens so that the inside and outside, where the axis of astigmatism in Scheme standard lens, the amount of the solution is then measured and the horizontal angle of the axial center of the lens, is axially degrees. But also grasp of the key issues with glasses 1, optometry equipment to advanced technology to perfect, to ensure accurate optometry. 2, no advanced computer equipment optometry, optician equipment and professional technical personnel is difficult with a qualified glasses. 3,quality control store purchase channels that directly affect the glasses qualified and unqualified. 4, the face and the frame is close to (your different face). 5, glasses and do not forget to credit cards. 6, asked in detail about the knowledge about the Cheap Tiffany and Co Necklace Jewelry Outlet glasses, optometrists commanded according to what is generally not a problem.

Apart from the high degree of astigmatism may be slightly reduced, where appropriate, the degree, usually astigmatism in degrees is best not to change, that is, without reducing the degree in order to achieve the best corrected Visual acuity and eliminate eye strain symptoms caused by astigmatism. Then when to determine the astigmatic axis and not easy to change itself, Results if the two optometry astigmatism axial is inconsistent optometry should be considered inaccurate, or scale enough to audition, to best corrected Visual acuity and refraction results as standard. Has height astigmatism or has oblique axis and anti-axis to of people, like a only eye of astigmatism axis in 180 degrees, another a only eye of astigmatism axis is in 90 degrees, in this special situation Xia enjoy out mirror to has may caused depending on property deformation, is oblique shaped, and tilt or appeared SAG, and convex bursting, or see property side wide side narrow, again has is see ground has inequality of feels,. When these abnormal conditions occur, you should again check the astigmatism in degrees and axial. If after checking the degree and astigmatic axial while they are correct, you will need to reduce the astigmatism in degrees. After checking again, although some mild dizziness, deformation, but after Dai Jing General adaptation period, most can get back to normal. As a special case, it clear prior to dispensing prescriptions and patients so that patients were prepared.

In fact, it can neither raise nor block the harmful rays. With Crystal glasses cool feeling is due to its low rate of infrared, ultraviolet, temperatures are relatively low because of the lens, not has a protective effect on the eye. World Health Organization noted that blindness due to cataract patients worldwide, 20% and UV-radiation. Eye cannot see and perceive ultraviolet light, and even less powerful ultraviolet light on the eyes have accumulated damage. And Crystal glasses with UV protection, UV spectrophotometer PERKIN-ELMER LAMBDA17 detected the Crystal lenses on the market, absorption of UV light by Crystal lens is almost zero. Crystal is a crystalline substance, its structure is not uniform, through which the light refraction, thus wearing the glasses to see clarity is poor. Some crystals contain radioactive elements, and also will produce different degrees of damage to the eyes. With Crystal glasses to protect eyes, is probably an illusion. And therefore, is inappropriate for those who work in outdoor activities and matching Cheap Tiffany and Co Necklace Jewelry Outlet crystal glasses.

Longer wear more difficult, oppression of the nose bigger. Frames to meet man's face, along with the increase in time, Discount Oakleys Flak Jacket Sunglasses Cheap frame deformation can occur, see something, it would rock. Prolonged use of the lens, light transmission and clarity are reduced, lenses are also worn, causing eyestrain and see clearly. Eye refractive changes alone, can't long time without glasses. She believes that increasing adolescent myopia tend to be under 18 years old, recommends an annual optometry glasses. Adult eyewear is relatively stable, but it should also be re-optometry glasses every two or three years. Dynamic change of the refractive error of the eye produces in the elderly, and changes the rotation led glasses, optometric is also recommended for two or three years back. 4 glasses and longevity Use both hands when you put on and removed his glasses and gently hold the frame legs, often with only one arm may damage the frame left-right balance, resulting in deformation of frame.

Eyes are a response to the physical and mental health and bodybuilding, bodybuilding in order to keep your eyes, to understand the following aspects of knowledge. 1. The glasses and face. Human face varies widely, but can be broadly divided into a long face, short face, and square face and round-faced, some downward angle cheek, cheek under the others. Wearing glasses like wearing clothes, chubby man wearing bar clothes seems much more fat, round face or flat-face man should not enjoy a square picture frame, if you wear a large square Cheap Oakleys Frogskins Sunglasses Outlet sunglasses, picture frame top to a solid color, the next for a transparent bottom, may "lengthen" the face, make up for defects. Glasses are for people with a sense of uniformity, spectacles and face shape. Rugged face, wear a solid color frame (such as the all black side), seems solid and steady. Chin, face, slender man accompanied by a pair of lighter weight shows long, are very delicate and elegant, graceful. If frames exchanged between the different faces of it, that would have a say a twisted, looked a little uncomfortable. 2. Eyeglasses with color. Our nation is a yellow race, but for individuals, color white, color black, tanned young men, wearing a pair of white frame, it contrasts, disharmony. Selection of color is a deep "colored" frame, it would be much better. However, the pale lesbian served with a white frame looks even more Haggard, only accompanied by pink or beige frames, in order to "increase your energy, makes people feel angry. 3. the glasses with age, child's head and body length is about one-fifth or one-sixth adults one-sixth children head and face are always short, flat square mirrors, and so it is inappropriate to apply black show long, wearing gold-rimmed Discount Oakleys Flak Jacket Sunglasses Cheap glasses not fitting, Best to wear a dark, transparent under bottom edge of frame. Younger people face plumper, preparing the frame width is good. Put on a bottomless box of glasses is also good. Let’s face stretch, look younger. 4. The spectacles and occupation. Preparation of glasses should also be given to the nature of their work. Glasses should be selected carefully. For example, the teacher's day class, teachers are the students look at the target, silver mirror is a center of attention. Therefore, teachers wore eyeglass frames to be as serious, generous, give students a sense of self-possession, poise, colorful frames are less appropriate, students easily distracted. As people age, face shape, body size, sex, occupation, hobbies, vary widely, there is no spectacle is the best option for people to reference. Described above is the summary of practice, is also in line with the aesthetic requirements, for readers ' reference. Glasses are different from earrings, necklaces and other ornaments, it is first and foremost in order to remedy the lack of Visual function in the body, thus, isn't the pursuit of its style, which affect health, farming and learning, a healthy premise, style fit, it's best of both worlds.

This also needs to draw your attention to.

Presbyopia is entered during the aging of the eye of biological change, where 45 per cent of the population, in line with the overall recession, the elasticity of the lens gradually weakened, and eye adjustment function as decreases to disappear. As long as the refractive abnormalities look outside 5M objectives without difficulty, just reading books and homework, are goals where you can see clearly that the older the more it far, some people until farther cannot be seen to be wearing old Cheap Oakleys Radar Sunglasses Discount glasses (a convex spherical mirror) to compensate for the lack of regulation. People accustomed to reading distance of 25~33cm. When reading and homework, only in the full adjustment of the two-thirds, l/3 retained as reserves situation, comfort. Eye squarely at the age of 45, with only 4. 00D adjustment, reading at 25cm. and near jobs, all regulation will be needed to see close objects, regulating all used up, read a few lines, or short-time jobs can also, if lasting visual fatigue symptom occurs. Hyperopia closer distance would have been far more squarely eyes, adjust the recession and early presbyopia. Near-sighted closer distances than face near the eye, 13. 50D more than a lifetime to avoid wearing the old sight glass, 13. 50D, as long as the degree of presbyopia myopia in no more than, there will not be any old phenomena. Presbyopia symptoms appear sooner or later; their nature of work, habits and physical fitness has a certain relationship. Workers and people who used to work at close range appeared early, music and art workers appeared later, infirmity, neurasthenia, vegetative nerve functional disturbance occurs earlier, able-bodied persons appear later. Presbyopia correction, should be integrated into each of the case may be. General reading and near-jobs at 33cm, depending on the distance, face the old sight Fake oakleys frogskins sunglasses cheap for sale glass and the eye is the relationship between age: 40 years old as +0. 50D,45 years of +1. 00D,50 years of +2. 00D,55 years of +2. 50D,60 years of +3. 00D,65 years of +3. 25D,70 years of +3. 50D。 Such as refractive errors, then after it’s refractive, reference to the relationship between age and face up to eye level of presbyopia correction. When deciding on the old prescription glasses, first to check the patient's refractive status, determination of refractive correction glasses single, then combined with his physique, nature and habits may be. In written work, sculpture, clocks, decoration, typing and get used to playing nearly and the infirm, and can give a little more. For music, art, woodworking, and stronger habits or physical place far away, you give a little less. Some elderly years has been rely on wearing old depending on glasses to reading and near job, and each across 3-5 years to put degrees adjustable high, 60 age found wearing has not adapted, needs will books put near, even disassembly glasses to see, this phenomenon of appeared should carefully check has no old afternoon I health cataract or diabetes sexual myopia, as can excluded, that is due to lens nuclear hardening dehydration flexor light index increased, makes flexor light rate enhanced of sake, medical Shang called nuclear sexual myopia or flexor sexual myopia, should for optometry check, At the audition on the basis of the results of presbyopia and the adjustment of age of opticians in degrees. General principles are: face eye from 40 to 65 year’s old, presbyopia at +1. 00D on the base of the counter increases by age.

Avoid radiation cause injury or damage to the eyes, and the most effective and the most commonly used method is wearing Discount Oakleys Flak Jacket Sunglasses Cheap glasses. So-called safety glasses is a filter, you can change the light intensity and spectrum. This kind of glasses fall into two major categories, one for the absorption, and the reflective, the former is most often. This kind of glasses can absorb some wavelengths of light, and the other wavelength light to pass through, so there is a certain color, the color of the light color. Such lenses at the time of manufacture, and in the general optical-quality glass in the recipe to join the metal oxides, such as iron, drill, chromium, strontium, nickel and manganese, as well as some rare earth metal oxide such as and neodymium, and so on. These metal oxides can make the glass of the light in a band of the electromagnetic wave as a selective absorption, such as the oxidation of the iron to absorb ultraviolet light. With this type of glass lenses can reduce some wavelengths through the lens is to reduce or prevent lenses cause injury. Different colors of the protective lens can absorb different colors of light, and the following are brief introduction of type safety glasses. A, absorption, optical filters 1, sunglasses visible through the rate of about 20 per cent of UV and IR absorption is better. The light green, neutral colors and are well-appointed, light tea, and many of the colors used to create shade and snow work safety Tiffany and Co Key Necklace Jewelry Outlet glasses. The light gray lens the color of the identified minimum impact; Light tea glasses to the sky looks dark and the green light through; Light Green Lens with red light through a reduction. 2, gas welding used eye glasses This mirrors the coloring agents are mainly aluminum oxide, carbon dioxide, cobalt, yellow green, and be able to fully absorb 500 urn THE FOLLOWING wavelengths of light waves, visible through the rate below 1 per cent, there can be only a few infrared, This kind of glasses for welding operations when welding. 3, welding used eye glasses Welding the UV, the eye-catching short exposure can cause cornea and membrane tissue damage (to 28 nm optical most serious). The strong infrared is very prone to eye lens opacities. Welding electrodes with goggles can be a very good blocking the infrared and UV light. Such lenses to optical-quality glass, aluminum oxide, and carbon dioxide cobalt and oxidized Chrome-Vanadium, coloring agents, and also to join a certain amount of carbon dioxide will increase to the ultraviolet absorption. The appearance is green or yellow and green. Can all block ultraviolet light, infrared light through Rate < 5%, visible through rate of about 0.1 per cent. The front coated glasses, had been introduced, the lens surface coating on a greater refractive index than lens itself reflects high rates of material coating, it will increase the light reflection, reduce the light through the intensity, so that you can protect your eyes from bright light and harmful rays. Practical Work in life, and it is absorbed, and reflective work together, using the colored lenses, re-plated one storey reflector, the filter role more, such as welding, arc welding, plasma cutting, and operator with the Cheap Oakleys Frogskins Sunglasses Outlet glasses, you can use this method.
Wearing sunglasses outdoors in the summer is also a kind of protection for the eyes.

Highest chances of generally flat-topped two-light is used, they only have a small area at the bottom of the lens to use as closer, lens around to upper to gaze far away and provide a good peripheral vision. Traditional of double light Cheap Oakleys Frogskins Sunglasses Outlet lenses for line double light of lenses, lenses by middle is divided into upper and lower two Department copies, is lenses of half following all as near points distance by with, they provides comparison good of wide of near points vision, for more long time Yu near points workers has more better of effect, architects, accountants, artist and other work nature phase near who, this species lenses can reduced head swing of opportunities.

June has entered the season of summer, and many friends have been wearing Cheap Tiffany and Co Necklace Jewelry Outlet sunglasses to block strong sunlight on eye irritation. Wear sunglasses, which not only protects the eye, and looks cool, both worlds. But experts point out that improper driver if you choose sunglasses, long wearing sunglasses that color is too deep, large and heavy, there is a traffic safety risk. Wearing sunglasses made errors of judgment Sunglasses’ main function is to keep out the Sun a powerful UV damage to the eyes, and thus play a role in eye protection. UV damage to the eyes, mainly on the cornea, lens and retina, too much UV radiation can cause conjunctiva hyperemia and edema, chronic conjunctivitis, also would result in the occurrence of cataracts. Then, people choose sunglasses to protect their eyes. Some people believe that sunglasses color is darker, and block UV rays as well. As everyone knows, tiny sunglasses, silent, it will be a disaster for the driver. If the driver is wearing sunglasses, moments into the tunnel from the strong light place, will have a visually "dark" dark for the time being, prone to accidents. Now research indicates that, Sun mirror of dark color can delay eyes put images rushed to brain of time, this Visual delay and caused speed feels distortion, makes wearing Sun mirror of driver made errors of judgment, especially Dang car, and motorcycle to 80 km of speed forward Shi, had deep of Sun mirror will put driver on situation of reaction time extended 100 MS, results increased has 2.2 m of brakes distance. Therefore, experts have said, serious accidents may occur in this case. Some experts pointed out that colors have filtered; drivers better not discolored Cheap Oakleys Radar Sunglasses Discount glasses, so as to avoid obstacles or pedestrians of the same color as the lens "filter", so as to be a hazard. Do not select the Parallax and aberration of lenses Traffic accidents caused by wearing sunglasses, and then the road will be banned? The road traffic safety Act does not make it clear whether the driver was wearing sunglasses. But if the sunglasses frame box width, heavy, will bring a lot of discomfort, sometimes acid, on the eyelid and cheek swelling, numbness, feeling sometimes noses, and seems to have a cold feeling. These negative symptoms are caused by wearing sunglasses that large and heavy, so choosing sunglasses should pay attention. Projection light quality sunglasses can be weakened, causing no chromatic aberration and Parallax, remain neutral, while maintaining vision clear, and can feel eyes and cool in the heat. "Parallax" means when put on glasses to read the road object is distorted or deformed, as well as the road conditions made the wrong judgment. "Chromatic aberration" refers to the color reflects the weakening or failure, severe, will not tell traffic lights causing traffic accidents. When buying sunglasses, choose sunglasses that have certain security properties, such as choose unbreakable Plexiglas to prevent glasses debris to scratch his eyes and face when the accident occurred. In addition, the spectacle of size, surface treatment, refractive lenses and curved arc, and so care must be taken when selecting sunglasses. All in all, driver not freeloaders, casually in the stall to buy Fake oakleys frogskins sunglasses cheap for sale sunglasses, instead of regular glasses store to buy.
When the sun gradually glares Discount Oakleys Flak Jacket Sunglasses Cheap sunglasses market also began to “hot up". Broadside big box, vintage fly-eye, smooth lines...... a variety of design allows the beauty of the girls pick dazzled, but they tend to focus only on the style at the time of purchase, the frame and lens color, but ignored the poor quality sunglasses possible harm to the eyes.
Some informal shops selling sunglasses, although looks very beautiful, but there are ripples on the poor quality of the lens, this lens wear long easily produce dizziness, vomiting and other symptoms, the greater the damage to the eyes.
Although some of the lens material with the naked eye to see that a glass or resin, but is not detected by the specialized equipment, do not know the quality is used as sunglasses, optical glass and optical plastic light transmission, wear resistance pressure, surface tension, anti-ultraviolet function were ordinary glass and resin are worlds apart.
So it looks similar glasses, the actual quality may vary. When buying Tiffany and Co Key Necklace Jewelry Outlet sunglasses, should choose reputable large stores and optical shops.
In selected a style, the most important thing is to check the lens, because it directly affects the quality of glasses. There is a small trick to judge the quality of the lens, the lens is placed in front of about a foot away, watching through the center of a fixed items, and then gently move up and down. If it is plain mirror, objects should not move, if the object is moving along with the lens or distorted, the lens is not flat, there are convex, so definitely not buy sunglasses.
Summer has the best selection of UV protection sunglasses. For specific UV filtering effect, we should note that UV index tag on the glasses. Currently, most sunglasses, UV index between 96% to 98%, dark colored lenses lens effect is better than that.
Sunglasses quite popular this year, " jump" colors orange, yellow, grass green, etc., but cannot be colored lenses block UV, visible light absorption color only affects the performance of it. The more vivid the color, the greater the impact on the pupil, if not fully block UV lenses, eye the damage is even greater.
Experts pointed out that for myopia, wearing contact lenses and eye disease and other potentially visually impaired people, the best choice to go to hospital or Cheap Oakleys Frogskins Sunglasses Outlet sunglasses glasses high reputation Center, and professional optometrists prescribe prescription choice.

In past of a years, many glasses factory including medium factory, are different degree to occurred had Sun mirror "splinter" phenomenon, to factory caused of immeasurable of loss, loss amount less who tens of thousands of, more of do up hundreds of thousands of, into mirror factory complained is lenses quality problem, and Tiffany and Co Key Necklace Jewelry Outlet lenses factory think into mirror factory itself also has problem, what is who of problem, actually does not important has, important of is find causes, for, combines in glasses industry years practitioners experience, on think comparison key of technology for analysis, hopes find problem of crux.
Frames bent is the key
Sunglasses camber usually consists of 600, 800, 1000, Bender bending and bending, most exports of sunglasses were 800, 1000 bending and bending, allowing the larger picture frame making the more difficult. Metal frame forming usually has automatically forming and manually around silk two species, Sun mirror frame forming main is first manual around silk again pressure bent of way, this on on pressure bent mold of precision has demanding, pressure bent mold and by mold manufacturers provides, glasses factory must on pressure bent mold precision repeatedly test, validation its whether meet products production technology, and quality standard of requires, this links to shut important, slightly accidentally, not only will effects products quality, and also will led to "burst tablets" phenomenon. Injection in addition to mold requires high precision, but also closely related to the injection temperature, pressure, time. Plate frames make is like that. Usually, after some changes in curvature eyeglass frames.
Frame welded can not be ignored
Sunglasses not only in terms of curvature than common optical glasses and sunglasses represent a trendy, popular style thousand odd hundred odd, such as Cheap Oakleys Frogskins Sunglasses Outlet, the bottom line is the more popular sunglasses, this class too Tin mirror frames, glasses and other more particular about welding is required. First of all, to make a jig before the welding, horizontal curvature of the fixture to match the frame camber must undergo testing, first to confirm before production, in production, often inspects the quality of products. Secondly, prolonged high temperatures, the jig will be distorted; precision needed to confirm the rear can be used. However, in actual production, because for various reasons, such as busy, ignore the detail control, and ultimately affect the Assembly quality sunglasses or even batch "blast".
Welding quality is not only this, both closely related to surface treatment of metallic glasses, the imprint left by welding, mainly through polishing, polishing can trigger frame deformation, thus affecting the effect of lens Assembly, is caused by a "blast", so during the soldering process, skills requirements to operators, types of welding wire, welding pool must be strictly controlled.
Surface treatment problems
Cutting is also a key quality control points
Cutting speed is not fast, too fast will not only accelerate blade wear and tear, and cut out the lenses are rugged, jagged, stress under light, you will find there are cracks around, mounted under the action of external pressure long after it would splinter. For drilling and notching of the lens as well.
Assembly direct impact on the final quality
If the above procedure is able to control effectively, then affecting the quality of lens is assembled, and which form a single frame, loading is very simple, but for large curvature, complex shape frames, put them there are a lot of tips. Such as, for no box, and upper and lower line, Sun mirror, completely by several screws put lenses fixed in frame Shang of, loaded films, must will mirror Kong Mao thorn removed, in mirror hole before and after put Shang gasket, again will has loaded epithelial sets of screws into mirror hole in the, with screw risked twist to lenses not loose, but artificial operation fundamental cannot control hard whether suitable, for prevent so and caused bad consequences, recommends manufacturers best used electric Rotary screws machine instead of artificial job. Otherwise, for ordinary acrylic, PC lens, there will be "cat's whisker".
Of course, even if the above links are in place, there is no guarantee that does not happen, "stroke" and "explosion" phenomenon, the lens quality is the determining factor. Frames like the body, is the face of the lens without the face, the body would have no meaning in existence, lens sunglasses at its core. Judgement of the quality of the lens, the main performance indicators must be delivered through instruments to detect the results, but does it splinter, current standards are not provided but can be judged by comparing the thickness of the lens surface strengthening layers. If the lens surface strengthened layer is too thick lenses hardness wear-resistant, but less toughness, easy splinter; strengthening layer is too thin, hardness, small easy to wear, but toughness is better, less likely to splinter. In addition, lenses, injection molding of raw materials all affect the quality of the lens.
To sum up, Discount Oakleys Flak Jacket Sunglasses Cheap glasses business only by constantly improving the quality of workers, improve processes, improve internal management, in order to minimize or avoid the "splinter".

Nowadays many glasses stores featured an expensive "natural" lens Cheap Tiffany and Co Necklace Jewelry Outlet sunglasses, can it really protect the wearer eyes in mind? This afternoon, a glasses shop in food Street, shelves, counters are put in a variety of fashionable, brightly colored sunglasses. One of the shop assistants picked up a pair of sunglasses list price is 430 Yuan, said: now people wear sunglasses of the natural crystalline lens. Wearing such lenses sunglasses are very comfortable, not only does not hurt your eyes, but you can also play the role of eye protection, quality assurance, each pair of glasses is testimonial. If you sincerely want it, dollars will get. "Followed by several other glasses shop, the store also recommended these so-called" natural "lens sunglasses, price ranges from two hundred or three hundred to one thousand or two thousand Yuan. Pure natural materials often have high market value, which also include natural crystals, actually sold on the market for two hundred or three hundred dollars in real prices of "natural" Crystal lens Cheap Oakleys Radar Sunglasses Discount sunglasses are not natural, but rather artificial, may even be smelted, so you do not have physical properties of crystals, much less the effects of eye protection. Ms Nguyen spent 45 dollars depending on the optical shop and bought sunglasses, you can wear glasses less than 1 hour, you feel your eyes dry, itching or tingling, Checked into the hospital, diagnosed with bacterial conjunctivitis, commonly known as "pink eye". City trade and industry survey found by law enforcement officials, on the lenses of the glasses of red and purple bubble, very rough, gloss dark, Shopkeepers say sunglasses were purchased last year, have played twice this year folded which are placed on the shelves to try on a lot of people and the inevitable pollution. Subsequently visited several optical shops in Wuhan found that Fake oakleys frogskins sunglasses cheap for sale sunglasses are in an outstanding position, looked almost picked up will be able to try on. Staff in disinfection of glasses need to feel surprised, never did.
1 ) Normally, 8 to 40% of the light can penetrate the sunglasses. Most people choose to 15-25 % of the sunglasses. Outdoors, most color Cheap Oakleys Frogskins Sunglasses Outlet glasses are within this range, but different manufacturers glasses light transmittance varies. Darker color glasses can penetrate 12% (outdoors) to (indoor) 75% of the light. Lighter brand can penetrate 35% (outdoors) to 85% (indoor) light. In order to find a suitable color depth and shading glasses, users should try several brands.
2) Although the color glasses for everyday use, but it does not apply to sports glare environments, such as boating or skiing. Sunglasses shading and color depth cannot be used as a measure of UV protection standards. Glass, plastic or polycarbonate lenses added ultraviolet absorbing chemicals. They are usually colorless, transparent lens even after treatment can also block UV light.
3) Color and shading the lens varies. Mild to moderate degrees of shading Discount Oakleys Flak Jacket Sunglasses Cheap sunglasses suitable for everyday wear. In bright light conditions or outdoor sports, should choose strong shading sunglasses.

It can protect your eyes when people receive free view sky glare hurt, but still clearly see the following scene. The top and bottom double gradient lenses dark in color, the middle light in color. They can effectively reflect the water or snow glare, so we do not recommend using sunglasses while driving, because they make the dashboard blurred.
5 ) prescription sunglasses can be tailored according to their needs, Addition to adding ultraviolet absorbing substances, the lenses that can be added in the production process dyestuff. In addition to the coloring material, manufacturers have developed filtered light chemical substances that can absorb certain parts of the spectrum.

6 ) tinted lenses having different light filter. Most tinted lenses can block 70-90 % of the light. Part tinted lenses filter certain wavelengths of visible light only, while light of other wavelengths not filtered. Therefore, different color or dye may change the color deepening effect on the ratio. Some colors, such as pink, blue or purple purely for decoration only, the filtering effect of light is poor. The best way to choose is to hand tinted lenses Tiffany and Co Key Necklace Jewelry Outlet sunglasses, arms straight, against a white background to determine its color.
And it is a variety of styles of Cheap Oakleys Radar Sunglasses Discount sunglasses sales season, shopping malls, stores, wholesale markets, sales of sunglasses spreads over thousands of dollars, the quality varies. Development zone, Xu pay a premium to get a pair of brands of lenses, only to discover in a few days, branded lenses were informed of the substandard products. In recent days, Mr. Tsui development zone a glasses shop glasses, fitted with a pair of pink glasses. However, he later search on the Web and found that this lens was released by substandard products and merchants refused to grant a replacement or return. Mediation by development zone Association, merchants expressed no knowledge about what this lens is not eligible, to the manufacturers for details, but agreed to return to Mr Tsui. Wholesale cheap sunglasses best seller In times square, three points and sunglasses such as night market stalls, market is flooded with low-quality and low-priced sunglasses. Sunglass style is rich, colorful, and the price is very cheap, and many young people buy. Some new sunglasses prices at 10 Yuan to 30, buy two or three more can save 3-5 million. Some sunglasses lenses there are air bubbles and impurities, sometimes with colored plastic. In this regard optical shop manager TSE, degrees, there are strict requirements of States for sunglasses and cannot exceed 9 degrees. Inferior sunglasses unable to resist ultraviolet rays, after wearing, foggy atmosphere people look like holes because the lens cannot filter UV and enlarge increase UV damage to the eyes. Mr Xie told reporters: "a pair of Fake oakleys frogskins sunglasses cheap for sale sunglasses because brands, materials, styles, colors and prices fell far short. To a larger glasses spectacle Shoppe to purchase in stores or shopping malls, and general product quality inspection, sanitary inspection, get a better guarantee. ” Polarized Sunglasses for eyes even better Best to select points by green grey and laser lens No professional identification of common sense of ordinary people, how simple and effective identification of lens quality? How to avoid buying into bad businesses selling defective glasses? In this regard, Mr Xie said, if you want to buy cheap sunglasses, or should choose the Volkswagen brand, it is best to select points by green grey and laser lens. When you buy sunglasses at the optical shop, may apply to the sales personnel will consult some Polarized Sunglasses, sunglasses as if in a two-layer lenses of this kind between the shutters, which can effectively block UV rays. If you do not have any test equipment, consumers can use the following simple detection of lens quality. Hand lenses from the eyes of 30 centimeters, observation distance from the lens. No jump when moving slowly, indicating transparency and uniformity of optical lenses is better. You can also draw a Grand Cross on a piece of paper with a thin line, hand lenses, with an observation of cross stroke of the eye lens shapes. Mobile lens, four-strokes inside the lens and the mirror cross strokes in a line outside. Observed in lenses with a pen cross at the center point of a smaller, this is the optical Center.

If more than the period of use, the Cheap Oakleys Frogskins Sunglasses Outlet lens may be difficult to distinguish the naked eye damage, while the lens will precipitate, which affect eye health.
Myth: Short sleep does not have to pick a mirror
The survey also showed that 37 percent of consumers will be wearing glasses nap; 19% of people will be wearing glasses overnight. This is serious damage to the eye health of error approach, because the contact lens material (except marked " shaped continuous wear contact lenses”) oxygen permeability cannot meet the basic needs of the cornea during sleep for oxygen. Wearing glasses overnight or nap can cause corneal hypoxia, resulting in varying degrees of corneal damage, but also causes the lens surface moisture loss, and even dangerous adhesion of corneal lenses.
Our traditional thinking, the eyes do not enter a volume of sand, but now we are able to accommodate into the eyes of the lens.
