Sunglasses are not only an accessory that allows you to look cool and not squint in the bright sun. It is also a means of protecting against ultraviolet rays, which may not have the best effect on eye health.

Studies have shown that the sun's intense ultraviolet radiation contributes to the development of cataracts, which in turn are a major cause of blindness. Even a single strong exposure to ultraviolet radiation on the eye can cause photokeratitis, a severe inflammation of the cornea. Children and people with light eyes are at greatest risk.

Things to remember when choosing glasses

Good sunglasses will help you avoid the unpleasant consequences of being in the sun. Here's what to look out for when choosing this must-have summer accessory.

100% UV protection

Such markings or UV 400 markings on glasses are the most important thing to look at when buying glasses.

The bigger, the better

Choose large glasses that cover your eyes not only in the front but also on the sides.

Darker doesn't mean safer

Impenetrable black lenses do not have to be very protective.

The color of the glass does not matter

It doesn't matter if you choose glasses with yellow, blue or gray lenses - this does not affect the transmission of ultraviolet rays. However, some colored glasses increase the contrast of vision, which is very convenient, for example, during outdoor sports games.

Polarized lenses protect against glare, but not UV

Polarized lenses remove glare from reflective surfaces such as water. This is convenient when driving or relaxing on the beach, but polarization has nothing to do with protecting your eyes from UV radiation.

Price is not important

Good glasses with 100% UV protection are both expensive and quite cheap.

When choosing glasses, pay attention to these characteristics, and you will not only have good glasses, but also healthy eyes.
