Answer:
Cataracts form when protein builds up in the lens of your eye and makes it cloudy. This keeps light from passing through clearly. It can cause you to lose some of your eyesight.
Most cataracts develop when aging or injury changes the tissue that makes up the eye's lens. Proteins and fibers in the lens begin to break down, causing vision to become hazy or cloudy. Some inherited genetic disorders that cause other health problems can increase your risk of cataracts
