A cataract in a human eye

A cataract is when the lens of the eye gets cloudy. Cataracts can cause short-sightedness (myopia), which means you cannot see things in the distance but can see things up close.

If not fixed by a doctor, some types of cataracts will cause blindness (which means you cannot see anything at all).
