A cataract is a clouding of the lens inside the eye. The condition can lead to a decrease in vision if clouding develops enough to obstruct your view. Left untreated, it is the most common cause of blindness in the world.
Cataracts are conventionally treated with surgery. Visual loss occurs because opacification of the lens obstructs light from passing through and being focused on to the retina at the back of the eye.
The most common cause of a cataract is biological aging and over exposure to ultraviolet light. Seeing through a cataract is similar to looking through a foggy window. People with cataracts commonly experience difficulty in appreciating colors and changes in contrast, driving, reading, recognizing faces, and coping with glare from bright lights.
While there is no way guaranteed way to avoid a cataract, wearing everyday eyewear and sunglasses that block 100 percent of UVA and UVB rays can slow the onset, as well as decreasing exposure to direct sunlight.
