Cataracts
Medically reviewed by Drugs.com. Last updated on May 4, 2025.
A cataract is a clouding of the eye lens. The lens works with the cornea to bend light as it passes through to the retina. It is normally clear. A cloudy lens makes it hard for light to pass through. Your vision may be cloudy, hazy, and blurred. You may develop a cataract in one or both eyes.
