Unapproved sunglasses with poor lenses can do more damage to your eyesight than no sun protection at all. The head of the ophthalmology department of the Consultative and Diagnostic Center of the Podolsk Regional Clinical Hospital Alexei Egorov warned about this.
— When you wear cheap, uncertified sunglasses, there is a big risk that, even though they are dark, they will transmit UV rays. At the same time, the eye thinks it is in low-light conditions and the pupil dilates noticeably.
In such a situation, the eye is strongly exposed to radiation, which can cause varying degrees of damage to the structures inside the eye.
To check glasses, Egorov advised using a simple method. You need to shine a UV flashlight through the lens. If the glass remains light, the glasses have special protective lenses and are safe for the eyes, according to reports 360.ru.
Tanning can be dangerous to your health. Literally, one trip to the beach can trigger a chain reaction in cells that, years later, will turn into a cancer diagnosis. In the evening in Moscow, I learned about the types of cancer that can arise from tanning from oncologist Violeta Portskhanidze.
