What is Cataract, Types, Precautions, And Treatment

A cataract is a condition in which the natural lens in your eye(s) becomes cloudy. When the proteins in your lens break down, things look blurry, hazy, and less colorful. So we can define cataract as a cloudy area in the lens of your eye. With age, cataracts become more common. We have a natural lens inside our eyes.

Lenses bend (refract) light rays that enter our eyes to make vision possible. It should be clear, like the top lens in the illustration.
