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.

- 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.
