Sunglasses and Diseases for not wearing them

Sunglasses are a visual aid. The lens are darkened to prevent strong light from reaching the eyes. Many people find sunlight too bright to be comfortable. During outdoor activities, the human eye can get more light than usual. Healthcare professionals recommend eye protection. They recommend it whenever you go outside to protect the eyes from ultraviolet radiation. Ultraviolet radiation can lead to the start of a cataract. Cataract is a disease where the light can't go through your eyes. Sunglasses have been used by celebrities and actors. People think they are used from a desire to hide or mask their identity. Since the 1940s, sunglasses have been popular as a fashion accessory. It is used mostly at the beach. Presbyopia is another disease and it makes you lose your vision to see near objects. Basal cell carcinoma is a common cancer which usually grows on the top of the eyelid. It is associated with sunlight exposure. Pteryquim is the last eye disease I know. It is common on the surface of the eye that is exposed to the sun. This disease spreads to the front of the eye and it require surgery to move it. This surgery needs to be repeated because the disease comes back. This is all I know and it is very interesting.
