When choosing sunglasses , you need to make sure that they really protect from UV rays. As a rule, the labels of quality models indicate the degree of protection against rays such as UVA and UVB. You can make sure that the glasses actually protect from ultraviolet radiation, for example, by wearing them for a week in the active sun. As a rule, there is an area around the eyes that is not touched by a tan. Simply put, "white circles" around your eyes will indicate that your glasses provide reliable protection. The choice of glasses for a vacation at sea should be approached as seriously as, for example, the choice of sunscreen .

Fans of buying sunglasses from stalls, at crossings and other street vendors need to know that cheap sunglasses, although they look very similar to branded ones and even have markings, still lose in quality and can cause possible eye damage from UV rays. This is explained by the fact that the degree of protection they do not meet the requirements. Yes, they have a certain degree of darkening, but if there are no UV filters, then there is a risk of corneal burns. The fact is that, by its nature, the eye instinctively protects itself from exposure to bright light by constricting the pupil, but the dimming of low-quality glasses serves as a trick for the eye, so to speak: subdued light causes pupil dilation, and the lack of UV protection allows harmful rays to penetrate into the eye. With the constant wearing of such glasses, unpleasant consequences are possible. If you want to make sure that your glasses will provide protection to your eyes, contact an optics salon, where they will test them on a special device.

What should be the color of sunglasses

If you choose sunglasses for frequent wear in sunny weather, then smoky gray or green lens colors will be the most successful tint colors. The former make it possible to perceive the colors of objects with little or no change, the latter absorb harmful rays better, and besides, the green color has a calming effect.

As for other colors, it is better not to get carried away with them too much. Red - promotes fatigue, yellow is more suitable for motorists, as it does not strain the eyes and thereby improves contrast. Rose-colored glasses, although considered glamorous, are still more suitable for computer enthusiasts, as they contribute to high-quality color perception on the monitor.
