How do cataracts affect your vision?

A cataract is a clouding of the eye's naturally clear lens. Your eye becomes like a window that is frosted or yellowed.

How quickly the cataract develops varies among individuals and may even be different between the two eyes. Most age-related cataracts progress gradually over a period of year.
