Everyone loves warmth and the sun. But we know that if you stay under the hot rays for a long time, instead of a beautiful tan, you can get burns and sunstroke. That's why we hide in the shade, put on hats, and use protective skin creams on the beach.

Types and effects of UV light on the eyes.
Ultraviolet is wave radiation, and there are 3 types of UV waves, depending on their length. The shorter the waves, the more dangerous ultraviolet light is for the eyes.
- C UV type. It has the shortest and most dangerous wave range. But it almost does not reach the earth's surface, as it is extinguished by the ozone layer.
- B UV type. Stimulates the production of melanin, which causes a tan. But its excess is harmful, as it can lead to burns and skin diseases. It affects the retina of the eye, the mucous membrane, and the cornea is dangerous because it can lead to temporary blindness and cataracts.
