Glasses are so firmly entrenched in the life of a modern person that many people can no longer imagine life without them. Sunglasses, corrective, protecting from wind and rain, or simply complementing the image of a business person - the benefits and importance of this stylish accessory are undeniable. At the same time, they also have drawbacks; one of the most serious is the appearance of lens flare on a sunny day. And if for office workers this remains a tedious, but generally safe nuisance, then for people of active professions such reflections can pose a serious danger. No wonder many people, forced to stay outdoors for a long time, prefer anti-glare glasses to conventional sun glasses.
Anti-glare glasses: luxury or a must?
On a clear day, any shiny object, mirror, polished metal or just the sun can be reflected in the lens of the glasses, causing a decrease in clarity of flashes. The reason is the insufficient absorption of light by the lens. It is to reduce this effect that a special anti-reflective coating is used.
The flash that occurred on the glasses of glasses worsens the view and distracts attention, not allowing a person to react to changing situations with the right speed. Wet road, mirrored shop windows, shiny surface of cars - all this increases the amount of glare and creates a danger to people both on the road and in everyday life.
Ordinary glasses also create an extremely unpleasant impression on the photo, because due to the reflection of the camera flash, only a shiny, blurry spot is often in place of the eyes.
It is especially important to get anti-glare glasses on time for those people who have vision problems. Reflections on the lenses cause the eyes to strain harder, which causes overfatigue of the optic nerve and a further drop in vision.
Anti-glare glasses for active people
For people whose life is connected with sports, driving a car or risky professions, sun glare are dangerous enemies. A moment of blindness can be an annoying trifle for an office employee, but for a cyclist or tennis player, this particular second can be decisive. That is why anti-glare glasses are so popular among fishermen, skiers, fans of water sports.
Especially important is protection against unexpected outbreaks for car drivers, because loss of visibility, even for an instant, is often the cause of terrible disasters. So, only in the Zurich canton of Switzerland, because of glare on the lenses, at least 5 accidents occur every month. Cars, whose drivers use anti-glare sunglasses, according to statistics, get into accidents much less often than the transport of their less prudent "colleagues."
Disadvantages of Polarized Glasses
Despite its many advantages, anti-glare glasses also have disadvantages that supporters of an active life should know.
Glasses with polarized lenses get dirty very quickly, they need to be cleaned much more often than ordinary optical glasses. At the same time, they are not very resistant to scratches, so it is recommended to wipe them with a special cloth - microfiber - using a cleaning spray.
Despite the widespread opinion, when working on a computer, they are no superior to conventional tinted or corrective lenses. In such glasses it is not very convenient to view LCD screens, they will be practically useless even if it becomes necessary to consider something near the sun. However, they still reduce the brightness, which will reduce eye strain by about 2 times.
It is also worth remembering that the anti-reflective coating of glasses is almost useless when the sun is at its zenith. The point here is the specifics of the refraction of rays in lenses.
Where to buy anti-glare glasses
Glasses with anti-reflective coating are gaining popularity every year, and there are many famous companies specializing in their production. So, the most popular brands in Russia are Polaroid, Lozza, Avanglion, Cucci, Persol, Ray Ban and many others. It is better to buy polarized glasses in company stores or large department stores, as in small stalls and on the market there is too much risk of getting a fake instead of a quality thing.
Sun protection is needed not only for people with perfect vision, but also much more for those who suffer from myopia. Ordinary tinted windows do more harm than good, as they cause the pupil to expand and thereby cause a retinal burn. In many stores specializing in optics, you can apply the necessary coating directly to the correction lenses for glasses. The anti-glare properties of such accessories are in no way inferior to the products of well-known brands and at the same time make it easier for people with low vision to walk along the street.
How to distinguish polarized glasses from ordinary
Unfortunately, the growing popularity of glare-absorbing accessories has led to a large number of fakes. In order not to purchase a useless item at a high price, you should carefully approach the purchase process.
Anti-glare glasses have some properties that ordinary light-absorbing glasses cannot boast of. They absorb part of the light rays and thus play the role of a filter. Therefore, the easiest way to exclude fake is to look at a brightly lit object first through the outside of the lens, then through the inside. On real glasses with polarization, the reflection intensity should change.
If doubts remain, try to put one glass on another and turn the top 90 °. Glasses with anti-reflective coating will become opaque.
Anti-glare glasses are an integral attribute of modern life, filled with high speeds and numerous bright objects. For many people, this thing is a great helper in both work and leisure. The main thing to remember when purchasing glasses with polarization: this accessory has not only advantages, but also disadvantages.
