Anti-glare glasses: the attribute of modern life

The glasses are so firmly embedded in the life of modern man that many people can no longer imagine living without them. Sun glasses, corrective, protect from wind and rain, or just complement the image of a business person - the benefits and importance of this stylish accessory is undeniable. At the same time, they have drawbacks, one of the most serious can be attributed to the appearance on a sunny day of glare on the lens. And if for office workers this remains tedious, but in general a safe trouble, then for people of active professions such reflections can pose a serious danger. No wonder many people, forced to stay in the open air for a long time, prefer anti-glare glasses to conventional sunscreen.

Glasses with anti-reflective coating: luxury or necessity?

On a clear day, any shiny object, mirror, polished metal or simply the sun can be reflected in the lens of the glasses, causing a defocusing spill. The reason is insufficient light absorption by the lens. It is to reduce this effect is used a special anti-reflective coating.

The flash on the glasses glasses worsens the sight and distracts attention, not allowing the person to react to changing the situation at the required speed. The wet road, the mirror windows of shops, the shiny surface of cars - all this increases the number of highlights and creates a danger for people both on the road and in everyday life.

Extremely unpleasant impression is created by ordinary glasses and in the photo, because because of the reflection of the flash of the camera in place of the eye is often only a brilliant blurred spot.

It is especially important to get anti-glare glasses in time for those who have vision problems. Lenses on the lenses make the eyes strain more, which causes overfatigue of the optic nerve and further fall of vision.

Anti-glare glasses for active people

For people whose lives are associated with sports, driving or risky occupations, sun glare is a dangerous enemy. A second blinding can be a nuisance trifle for an office employee, but for a cyclist or a tennis player this second can be decisive. That's why anti-glare glasses are so popular among fishermen, skiers, fans of water sports.

Especially important is the protection from unexpected outbursts for drivers of cars, because the loss of visibility, even for a moment, is often the cause of terrible disasters. So, only in the Zurich canton of Switzerland because of the glare on the lenses there are at least 5 accidents per month. Machines, drivers who use anti-glare sunglasses, according to statistics, fall into accidents much less often than the transport of their less prudent "colleagues."

Disadvantages of glasses with polarization

Despite their numerous advantages, anti-glare glasses have disadvantages that supporters of active life should know.

Glasses with polarized lenses are very quickly contaminated, they need to be cleaned much more often than conventional 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 do not exceed the usual tinted or correcting lenses. In such glasses it is not very convenient to view the LCD screens, they will be practically useless even if you have to consider something near the sun. However, they diminish the brightness, which will reduce the eye tension by about 2 times.

Also it is worth remembering that the anti-reflective coating of glasses is almost useless when the sun is at the zenith. The point here is the specificity of the refraction of the rays in the lenses.

Where to buy anti-glare glasses

Glasses with anti-reflective coating are getting more and more popular every year, and there are a lot of famous companies specializing in their production. So, the most popular brands in Russia are Polaroid, Lozza, Avanglion, Cucci, Persol, Ray Ban and many others. To get polarized glasses is better in firm shops or large department stores, since in small stalls and in the market there is too much risk to get a fake instead of a quality thing.

Protection from the sun is needed not only for people with perfect vision, but also much more for those who suffer from myopia. Conventional darkened glasses do more harm than good because they cause the pupil to expand and thereby cause a retinal burn. In many shops specializing in optics, you can apply the necessary coating directly to corrective lenses for glasses. The anti-glare properties of such accessories are not inferior to the products of well-known brands and at the same time they facilitate people with poor eyesight walking along the street.

How to distinguish polarized glasses from conventional

Unfortunately, the growing popularity of glare-absorbing accessories has led to the emergence of a large number of fakes. In order not to get a useless item at a high price, you should pay close attention to the purchase process.

Anti-glare glasses have some properties that ordinary light-absorbing glasses can not boast of. They absorb a part of the light rays and because of this play the role of a filter. Therefore, the easiest way to exclude a fake is to look at a brightly lit object first through the outer side of the lens, then through the inside. On real glasses with polarization, the reflection intensity should change.

If you still have doubts, try to put one glass on the other and turn the top one 90 °. Glasses with an anti-reflective coating will become opaque.

Anti-glare glasses are an essential attribute of modern life, filled with high speeds and numerous bright objects. For many people this thing is an excellent assistant both in work and in rest. The main thing about what it is worth remembering, buying glasses with polarization: this accessory has not only advantages, but also drawbacks.
