Cataracts

Cataracts are clumps of protein that collect on the lens of the eye and interfere with vision. Normally light passes through the lens, the clear tissue behind the pupil, and focuses on the retina. The retina is the light-sensitive layer of the eye that sends visual signals to the brain. A cataract happens when the clear lens becomes cloudy.

Most cataracts develop slowly over time and are a natural result of aging. Once cataracts become large enough that vision loss interferes with everyday activities, such as driving, reading, or watching television, they should be surgically removed.

Cataract removal is one of the most common operations performed in the United States. According to the National Eye Institute, roughly 90% of people who have cataract surgery have better vision afterward.
