Lenses was also known as "photographic lens." Because silver halide chemicals added to the lens, so that the original transparent Tiffany and Co Necklace Jewelry Outlet Store colorless lenses, glare met, it will become colored lenses, do protection, it is suitable for indoor and outdoor use.

Lenses containing micro-crystals of silver halide optical glass production, according to the light color interaction becomes reversible reaction principle, can quickly darken in sunlight and ultraviolet radiation is completely absorbed ultraviolet light, visible light neutral absorption; return to the dark, can quickly restore colorless and transparent, Lenses photochromic properties with permanent reversible, Due to the addition of silver halide and copper oxide have been integrated with optical glass, so the color glasses can repeatedly change color, long-term use, both to protect the eyes from glare stimulation, but Tiffany and Co Outlet also play a role in vision correction.

Lenses what effect? It's mainly used for open-air field, snow, indoor strong light source in the workplace, to prevent sunlight, ultraviolet light, dazzling glow eye damage.

In plain words, is under strong light, the inside of the silver halide light shines again changed into black silver particles.

Which brand of photochromic lenses is better?

This is not much difference, in general Cheap Mac Cosmetics Makeup wholesale Outlet can be a big brand of photochromic lenses is mainly a more mature technology, produced by the more powerful UV lenses, such as Transitions photochromic lenses, it is possible to block 100% of harmful sun long-wave ultraviolet A and ultraviolet B, color effects and color adjustment time is also more reasonable. This precision and meticulous commodity spectacle is best not to be careless cheaper, or if what constitutes harm to the eyes can not make up.

With the demands of modern life, the role of colored glasses is not just the role of eye protection, it is art. A suitable colored Fake Oakleys Frogskins Sunglasses Cheap for Sale glasses, accompanied by the appropriate clothing that can bring out a person of extraordinary temperament.

Today, more and more myopic crowd, so many people had to go with a pair of glasses to solve vision problems; optional lens Cheap Mac Cosmetics Makeup wholesale Outlet glasses that cannot be missed, Essilor, Hoya, the Soviet Union took and Zeiss, because most of the lens material becomes high preferred glasses family. But filled with cottage, counterfeiting and other products often found not new and was beloved glasses Essilor lenses are inevitable. Beware of fake glasses buy glasses; following practices on

You can identify the lens of authenticity.

A: Look lens film color. By looking at the color of the reflective film of the lens is determined. The vast majority of brand Fake Oakleys Gascan Sunglasses Cheap for Sale lenses green film, in addition to blue and purple and so on film; film lens color is rather special, for a touch of yellow-green, relatively few other brands on the market this color.

Two: the lens fog was observed in addition to 1.74 marks Essilor lenses, all of Essilor II or diamond crystal diamond crystal lens cleaning Chile has "CRIZAL" the diamond crystal mark, you simply facing a lens Ha tone will be revealed, but if the size of the mirror is very small circle have been worn or partially processed cutting edge may be worn (low probability), then you need to distinguish between the outside of the packaging.

As if to distinguish between "diamond crystal II" and "Diamond Crystal Chi Kit" You can put the lens into the water washing, clean the lens on the basic wisdom not wet, wet part will show the security word mark "CRIZAL", while the diamond crystal II or other brand Tiffany and Co Necklace Jewelry Outlet Store lenses do not have this effect.

PC resin lens and lens which is better? Tiffany and Co Necklace Jewelry Outlet Store Glasses when we encounter salespeople always asked the question, "What kind of material do you want to select the lens; our side resin lens and PC lens sell better" glasses when we are not encounter to this question then, what is the resin lenses, what is the PC lenses do, they are any different, LOHO glasses senior living optometrist to introduce you to a resin lens and PC lens which is good.

Resin lens:

Resins are derived from a variety of plants, particularly conifers hydrocarbons (hydrocarbons) class secretions. Because of its special chemical structure and can make use of this paint and glue are valued. It is a mixture of several polymer compounds with different melting points so. Resin can be divided into two natural resins and synthetic resins. Resin types are very, very much, is widely used in light industry and heavy industry among people in everyday life among often be seen, such as plastics, resins glasses, paint. Resin lenses is to use chemical processing synthetic resin lens material after grinding

Pros: resin lens is composed of two fatty alcohol glycol and propylene polymerization reaction. Light weight, impact resistance, high temperature, light transmittance Cheap Mac Cosmetics Makeup wholesale Outlet is good, close to the glass lens performance, can block ultraviolet rays.

Disadvantages: the surface abrasion resistance, chemical resistance than glass is poor, the surface is easy to scratch, a large water absorption than the glass; high coefficient of thermal expansion, poor thermal conductivity, low softening temperature, easily deformed and affect the optical properties.

PC lenses:

General resin lenses are thermoset materials, namely raw material for the liquid to form a solid lens after heating. PC piece called "space film", "cosmic piece."

Advantages: light, lighter than traditional glass 57%, security, its impact resistance is 60 times that of glass, do bulletproof Fake Oakleys Gascan Sunglasses Cheap for Sale glass thickness 2.5cm. Thin, with a refractive index of 1.6 is equal to CR-39 lens thickness

Disadvantages: poor wear resistance

Now more and more joined the ranks of the precious metal Tiffany and Co Necklace Jewelry Outlet Store wedding ring material, you can distinguish between platinum and palladium it? What white K gold is? Read through this wedding ring material guide, you may be able to more clearly know what they want the wedding ring material, in order to find the most appropriate ring.

Platinum

Commonly known as platinum, a rare natural white metal, is famous for its strong and pure.

Reason that people loved: Platinum high-density gives it unusually strong, which means that it can properly protect and secure the diamonds or other precious stones. And it is natural Harmonie, worn on sensitive skin without any problems. When platinum was scratched when (all metals will be scratched), it just produces metal displacement, not the loss of quality. So your ring can resist years of erosion. In addition, because it is a pure white metal, so it does not give the central projection on any color gem.

Gold / white K gold

Gold: These natural yellow metals usually kneaded with various metals in order to obtain additional hardness - it usually has a purity of 70-75%. So inlay on it will present a iridescent Fake Oakleys Gascan Sunglasses Cheap for Sale gems, including white, green and pink.

K White Gold: Gold plated layer of rhodium on, let it become white, but as time goes by, the coating may be worn away, it also exposed the original color.

By reason people love: it is a more common metal, so compared to some other metals, it is cheaper. And it can be incorporated into different alloy, which means it can decide according to their own preferences tone.

Rose Gold

This pink tone metal is an alloy of gold and copper blend. Adding more copper alloy that rose more full-bodied tone.

Reason that people love: Why do people particularly fond of rose gold, one of the reasons is its potential significance. White K gold on behalf of friendship, gold represents loyalty, and rose gold on behalf of love. In addition, it is very strong, and Cheap Mac Cosmetics Makeup wholesale Outlet with a variety of different colors are very nice.

Strong sunlight in the summer, many people are wearing Fake Oakleys Gascan Sunglasses Cheap for Sale sunglasses. Anti-reflective protective lenses, color lenses, color lenses, polarized lenses, color lenses…… Colorful sunglasses on the market, some people tend to buy their favorite color and style, completely ignored the sunglasses the UV effect.

What kinds of lenses can suntan without hurting glasses? In response, Beijing Tongren hospital optometry professional optometrists Lv Meng warned that sunglasses do not prevent Sun, may hurt the eyes. conspicuous when it encounters a glare and UV rays without shelter, the light will go directly to the pupil, thus cause damage to eyes. Sunglasses in different ways (such as polarization, color, coating, etc) play the role of UV. Sunglasses can block UV rays and glare, because of added a special coating on the lenses.

Lv Meng warned that buying sunglasses must go to a regular Tiffany and Co Necklace Jewelry Outlet Store store. At the time of purchase, to look for the package "100% UV" and "uv400", "ultraviolet" logo.

While the color of the lenses mentioned, United States experts in blindness prevention Union recommended that, in General, summer Brown, and Tan is a better choice of lenses, and the more strong outdoor sunlight, should choose the dark sunglasses. Partly because of these colors better lens glare, UV absorption and filtration; on the other, is a Brown lens provides good color perception, wear can still distinguish colors clearly, tinted lenses can block the surface of smooth and shining Ray, under the glare of the Sun to be able to see the object details, driver's tinted glasses is a better choice. And green glasses have sold well in the market, can reduce the level of visible light enters the eye, especially dark green, can absorb heat. While blue, pale yellow and pink lenses are not suitable for wear in bright white light, because Cheap Mac Cosmetics Makeup wholesale Outlet anti-reflective effect was weak.

Glasses have become an indispensable part of myopia friends, again thousands Tiffany and Co Key Necklace Jewelry Outlet glasses store to find a suitable glasses are not very easy, so the glasses must be thinking how good care of it, because now a good the price is not very cheap glasses; although unlike glasses lenses so squeamish, but do not take good care of it or use will shorten the life of many. In fact, more finicky place glasses or lenses in it, so a lot of glasses would ask some questions about lens care.

In fact, glasses and maintenance is not complicated, the most important thing is to persist; if long to do, I believe the glasses will long for you, to bring you a comfortable feeling to wear glasses next LOHO life experts to introduce! Some maintenance methods spectacle lenses.

A: daily cleaning glasses method

1, the best wash with water and then made a small soft brush, the crevices of fouling removal, When to use Cheap Mac Cosmetics Makeup wholesale Outlet glasses cloth to wipe the lens wipe in one direction, not in circles.

2, the general length of time more serious fouling glasses, you can use a professional cleaning cloth to wipe the glasses, or outside now have a professional ultrasonic cleaning glasses can be.

3, because the hand regular contact lenses contain oil, it is recommended to use detergent to clean. After washing detergent does not rinse with water, then with a soft cloth paper or glasses, you can.

4, when cleaning glasses, it is best to live a hand nose bridge frames, one hand gently rinse the dirt at the spectacle;

5, in general, the lens two days to clean it once;

II: Maintenance of Fake Oakleys Frogskins Sunglasses Cheap for Sale glasses

1, when the glasses removed, should be handled with care and placed face-up on the lens to prevent the lens surface wear;

2, do not put the glasses in humid environments such as high temperatures or sunlight exposure, so as not to damage the lens;

3, adhere to wash less rub, is the best way to maintain the lens;

Three: Note glasses daily use

1, when the glasses off, should be placed in a place away from children to avoid eye piece is broken or the child harm.

2, the glasses should avoid contact with the organic solvent, avoiding high temperature and close to the fire source.

3, when a long time without glasses, place the glasses on a dry mirror box;

4, eyeglass frames should always check the screws on whether there is loose and frame deformation phenomenon. If it is found loose screws to be tightened in order to avoid breaking off the lens.

As long as you adhere to the proper use and maintenance of the above methods of cleaning and care glasses, Cheap Ray Bans Wayfarer Sunglasses Outlet Sale glasses can be a very good continuation of life.

Now our daily lives, learning a lot of time entertainment are inseparable from the computer, the computer must have radiation, because the radiation computers are all on our own body injury. Resin Cheap Mac Cosmetics Makeup wholesale Outlet generally worn by everyone, then there asked, the resin lens radiation do not all resin lenses are radiation, because the so-called radiation, is in the process of glasses, adding a compound dielectric material in the production, posted on the lens surface radiation film.

Radiation resin lenses do, only to be able to radiation coating resin lens is the use of the physics of radiation interference phenomenon in the market, there are many plain of radiation glasses, is designed for non-myopic or people who wear contact lenses prepared resin lenses radiation it, lenses using energy reflected or absorbed radiation, infrared lenses absorb blue, yellow and green lenses absorb ultraviolet and infrared. Impact from radiation to Fake Oakleys Frogskins Sunglasses Cheap for Sale glasses, wearing a pair of coating resin lens is necessary.

Resin lenses How to maintain, after the surface coating resin lens, effectively blocking the harmful ultraviolet rays of the eye injury, eye protection and greatly improve the clarity of vision, but if you pay attention to maintenance, the film resin lens surface is abrasions, clarity decreased, and affecting wearing effect. Resin lenses how to care for, pay attention to the steps of cleaning, appliance cleaning methods. Proper maintenance, in order to make better use of resin lenses brings convenience.

Resin lenses should be completed Miao scratch heat, fumes should also be taken to avoid erosion, do not bathe with glasses, do not wear glasses, glasses should be properly placed in the glasses case. Wipe resin lens at the time, should use special glasses cloth, do not use other ordinary cloth, as this is likely to cause scratches on the lens surface, the impact of clarity. Resin lenses how to care for, resin lens due to its own reasons, the service life of about a year, but will increase the excessive use of eye fatigue.

Resin lens how to clean, resin lens is a kind of resin material, optical lenses, because there are many advantages, it gradually replaced the Cheap Ray Bans Wayfarer Sunglasses Outlet Sale glass lens, but how to clean resin lenses, is that many glasses family would like to know the answer, because the glasses piece is dirty, not only does not affect vision and beautiful to others left a sloppy impression, so clean resin lenses is necessary.

Resin lens how to clean, before resin lens cleaning, rinse with tap water, you can also use a mild soap or a special detergent, then special glasses cloth. Resin lens how to clean, hand sanitizer, dilute with water. Best use shampoo or shower gel, because the two more oil, will produce a protective film, while the role of water fog would hand sanitizer in your hand rubbing the foam is applied to the two fell out of the lens surface, and then the finger pulp close to the lens wipe back and forth. Try to avoid nails to scratch the lens.

Rinse the lenses, not too much water, smaller can. Lens with water into a 45-degree angle and slowly pan washing, try not to let the water flow to the other side of the lens. How to clean resin lenses, rinse resin lenses, vision is particularly clean, there are many optical shops for cleaning lens Tiffany and Co Key Necklace Jewelry Outlet glasses have this free service, if they cannot deal with, or go to the optical shop to clean more at ease.

Consumers choose the Fake Oakleys Frogskins Sunglasses Cheap for Sale lens when selecting an increasing proportion of color film. More consumers do not understand the color film, only occasionally found himself a friend of the same pair of glasses lens at different times have different colors and feel strange.

First, what color film is?

Modern society increasingly serious pollution of the atmosphere, the ozone layer has been damaged a little, glasses exposure to UV sunlight. Color film is slightly discolored lenses containing silver bromide grains factor and copper oxide. When bright light, silver bromide decomposition of silver and bromine, decomposition of tiny grains of silver, so the lens showing dark brown; When the light dimmed, silver and bromine in the copper oxide catalysis regenerate bromine silver, so the lighter the color of the lens again.

Second, the advantages of color film than ordinary lenses Where?

UV rays can "sunburn" surface of the eye, the cumulative effect of long lead directly to a variety of eye diseases. Such as photokeratitis, while also grow healthy macula of the eye surface. Two other common cause pingueculae and pterygia.

According to a recent survey showed that the cumulative effect of long-term exposure can cause eye and around sensitive areas and age-related serious diseases, including cataracts and melasma sex under ultraviolet light, which is the cause of blindness in the elderly. According to data released by the World Health Organization show that 16 million people worldwide each year due to cataract blindness, of which 20% is due to the long-term exposure to UV-induced UV hazards unusual.

When color Cheap Ray Bans Wayfarer Sunglasses Outlet Sale glasses encounter ultraviolet light, its coating layer immediately in blocking ultraviolet intrusion while quickly darken substantially blocking UVA and UVB infringement of our eyes. Color film in the developed world for its health, convenience, aesthetics and many other advantages, has long been recognized by health-conscious consumers annually Lenses customers to double-digit growth rate.

Third, the price of color film is how much it cost?

In China, the color film glasses are the new face of retail, general consumer awareness of color film still, there are many question marks, but the mirror-plated 'photochromic materials' color film is about twice the normal lens, higher Price also hindered its popularity. In actual fact, as the transparent color lenses can be worn glasses indoors, outdoors and can be comparable to the price of anti-UV sunglasses, buy a pair of color lenses with two pairs of lenses than the cost is much lower.

Fourth, change color film color

A sunny day when: In the morning, the clouds thin air, less ultraviolet barrier, reaching the ground is more, so the depth of the morning Lenses relatively deep. In the evening, ultraviolet light is relatively weak, as the evening sun farther from the ground during the day due to the accumulation of fog after blocking most of the ultraviolet rays; so this time the color depth is very shallow.

2, cloudy day when: UV sometimes not weak, it is possible to reach the ground, so the color of the lens is still able to change color. It does not change color in the room almost transparent color lenses can provide the most suitable UV and glare protection Tiffany and Co Key Necklace Jewelry Outlet glasses in any environment, timely mediation lens color according to the light, at the same time protect eyesight, anytime, anywhere for eye health protection.

3, the relationship between color film with temperature: Under the same conditions, as the temperature rises, the color of the lens discoloration due to temperature rises slowly as shallow; Conversely, when the temperature decreases when color lenses will slow slow dark. So why summer light color, winter color depth is the truth of.

Three types of five, color film

1, the surface layer style: the lens surface is coated with a thin little discoloration agent. Its advantages, background shallow near bottomless appearance was nice; but the biggest drawback, discoloration time extremes, especially high temperature, it is very easy to not change color.

2, into the formula: in general the lens surface into 1-2 mm discoloration agent advantages: a little bit of background, color uniformity. But Disadvantages: Since only a little discoloration on the surface, a lower surface does not change color, making it easy layering unchanged.

3, incorporation-type: in the monomer feed on mixed well discoloration agent, produced the entire lens is filled with color agents; advantages of color for a long time, high temperature; shortcomings, the lens in the middle and edge color will be a little gap. But we all know, the edge thickness and the thickness of the middle of the center of the lens is completely different, so look at it to color deviation; but the glasses are processed glasses when cutting pieces to take the middle part, a good pair of processing after the finished glasses, they will not dimensionless brought color problems. This process is made out of color lenses within two years of the show consistent.

After two years should be re-optometry, re-glasses, no Cheap Mac Cosmetics Makeup wholesale Outlet glasses are not worn too long advocated.

The main color Cheap Mac Cosmetics Makeup wholesale Outlet glasses lens discoloration membrane, is the use of light-sensitive material for forming an organic film layer of color, and this resin layer coating the lens surface is the lens surface or penetration into the resin, so as to achieve color effects, characterized in that: lens background light, indoor almost colorless, color is not affected by the degree of speed. The most representative is the transition (Transitions) the company's color technology, life expectancy is longer, usually 3-4 years. Color glasses for patients that can correct refractive errors, can also act as sunglasses outdoors, isolated ultraviolet light, adjust the light entering the eye, maintaining proper vision; status regardless of their color, it is always good to absorb ultraviolet light. Several of the major indicators of color film, color life, color speed, color uniformity. Domestic brands more color film, color film, but the main problem many domestic slow lens discoloration, fading slowly, deep color, color is not exactly easy, especially after wearing for some time, will find life color, color speed, color uniformity decline the more serious. Better the performance of well-known brands, mostly by the United States and France Corning Transitions color film technology. For example, the Japanese have adopted nikon Transitions discoloration technology. The fifth-generation ESP color film of the film composite technology is more mature, noble plated high permeability layer, its interior visual effects more clearly than ordinary hard lenses. Color depth also improved, less dependent on temperature, at 23 degrees Celsius sunshine comparable sunglasses in high temperature environments, can get other color than the current product shades deeper outdoor visual effects. And color fade faster than the first generation of Transitions Fake Oakleys Frogskins Sunglasses Cheap for Sale lenses faster. First, the principle of color glasses Currently used photochromic lenses are divided into two kinds: the base color lenses and film color lenses. Lenses base comes mainly from light-sensitive material mixing glass lenses, color lenses by French glass version Corning Incorporated (corning) first developed successfully, the principle is the use of ultraviolet light-sensitive silver halide (usually silver chloride) microcrystalline implantation of ordinary glass material, which is characterized by lens background darker indoors will be showing a hint of gray or brown. Speed of color lenses by, the higher the degree of color change more slowly, when the thickness of the lens is not the same, the color of concentration also will be different - a high negative lens edge thicker than the center, thus increasing the density of the color at the edges is also. High density is very easy to identify the color, light color, high refractive power leads to the phenomenon of the center, and the periphery of the ribbon has a very deep. Impact on the positive lens on the contrary, the middle area very dark, and the surrounding light color. High hyperopia can find the central lens look out too affected. Since the light-sensitive material is mixed into a glass material, resulting in a shorter lifespan color lenses, usually in about 1-2 years (the life of the president of some imported materials), to be followed by the Cheap Ray Bans Wayfarer Sunglasses Outlet Sale lens and change the background color occurs between the deepest the difference is reduced, the final color is not. Most of the photochromic material of gray and brown, graying and tea becomes known, other colors may also be obtained through a special process. All the glasses, including single light, double light, gradient lens can be manufactured using a photochromic material. In recent years, the development of light-induced discoloration of resin lenses faster, currently on the market is the most commonly used material for the refractive index of the resin discoloration 1.50,1.56,1.59 (PC material), 1.67, and so on. Second, the color glasses Material A glass and a resin material of the light-induced discoloration of the main difference is that between the manufacturing process. Glass photochromic lenses will change color material - silver halogen, mixed together with the glass material is dissolved, through the lens blank manufacturing; while resin photochromic lenses change color substances introduced methods are mainly two kinds of coating and surface penetration. The best way is to surface penetration method. The manufacturing process, the photochromic material can be accurately controlled penetration into the front surface of the lens ~ 150 | ìm. Will determine the uniformity of penetration of the final performance of the lens' surface "applies to any kind of penetration of the refractive power of the lens, have the same performance of a uniform color effect does not occur in the glass photochromic Tiffany and Co Key Necklace Jewelry Outlet lenses color uniformity.

Currently, there are many methods in the treatment of child myopia, some even claims to be able to let the children take off Cheap Ray Bans Wayfarer Sunglasses Outlet Sale glasses in the short term. In fact the vast majority of myopia (especially above 300 degrees), inter alia through surgical methods can let some people take off glasses, other "methods and instruments", if we can prevent the development of myopia is not easy (in fact, many "method and apparatus for" even this effect are not up to it!) Myopia is meant to take off glasses and can get real clear, healthy vision of comfortable, durable, at least so far it is impossible.

Myopia is common eye abnormalities, and its work on prevention not cure. In addition to these technical means, in the developmental stages of children and adolescents, and good eye health habits, plenty of outdoor activity, a balanced diet, such as nearsightedness myopia controls the integrated prevention and control measures are effectively essential natural elements. Deliberately refuse to glasses, hastily took off his Cheap Mac Cosmetics Makeup wholesale Outlet glasses, blind implementation of "myopia treatment" can have an irreversible adverse effects to the eyes and even harmful.
Special reminder: need periodical replacement of glasses

2, lenses for spectacles of "soul", a pair of high quality optical quality of the lens must have a high degree of precision in order to ensure the quality of light in retinal Imaging. And lens choice must also take into account safety, light weight, easy to wear and so on.

3, in a period of growth and development of children, the refractive State of the eye (degrees) in dynamic changes, therefore, children wearing glasses are required periodically (approximately 1 per year over 6 years old, 6 years of age approximately 1 every six months) Mydriatic refractometry, the timely replacement of Fake Oakleys Frogskins Sunglasses Cheap for Sale glasses, synchronized to guarantee change of glasses and eye development.

For a person who wears Cheap Ray Bans Wayfarer Sunglasses Outlet Sale glasses, is most worried about is: glasses with deeper and deeper, or glasses with long eye shape. Eye specialist said it was all a misunderstanding of glasses, wear appropriate glasses can only be good, does not affect the eyes.

Causes of myopia in addition to intrinsic factors, such as genetic and developmental, mainly because of overuse, keep eye inner and outer muscles strained for a long time without a break, with the passage of axial a variable-length, images cannot be brought together on the retina, not see distant objects.

Principle of wearing Tiffany and Co Key Necklace Jewelry Outlet glasses can be concave, shifted focus of the image, so that the vision can be corrected. So in principle, wearing thick glasses and do not cause nearsightedness.

For some young people wear glasses, and deeper, glasses increases for two main reasons: one was the result of adolescent physical development, adolescents in the growth process, axial are in constant development, so that the eyeball increases, resulting in myopia increase; the second is the original myopia risk factors didn't break.

With deeper and deeper might also be because the glasses don't fit, rather than a problem with the glasses. Development of adolescent eye adjustment ability is stronger, if there is no formal medical optometry, astigmatic axis and PD error, that wearing Cheap Mac Cosmetics Makeup wholesale Outlet glasses is likely to be higher than they actually, which can cause eyestrain, degree of myopia caused more severe. In addition, poor eye habits can cause vision loss. Deepen the degree, the most important reasons is the eyes of overload, especially the use of mobile phones, tablet computers and other electronic products, juvenile overuse, fault is not the glasses themselves.

As for glasses for a long time can cause exophthalmos. Eye strain is often due to wear all year round-framed glasses oppression nose, take off the glasses gives an illusion-eyed in appearance. In addition, high myopia in itself leads to eyeball extension problems, from appearance characterized by proptosis; this has nothing to do with the spectacle itself. Spectacle correction properly, can also help to slow down the phenomenon.

Experts warned that scientific spectacle, the first thing to go to regular hospitals for science and optometry, choosing the right glasses prescription. Secondly, in terms of wear, if degrees in more than 200 degrees, you should always wear Fake Oakleys Frogskins Sunglasses Cheap for Sale glasses, which help to correct myopia, ease eye strain. If below 200 degrees of low myopia, or you can choose to wear, if necessary.
