Cataract Blindness

A cataract is a clouding of the lens in the eye leading to a decrease in vision

 

Cataracts are most commonly due to aging, but may also occur due to trauma, radiation exposure, be present from birth or occur following eye surgery for other problems

Prevention includes wearing sunglasses and not smoking

 It can affect one or both eyes. Often it develops slowly.

Symptoms may include faded colors, blurry vision, halos around light, trouble with bright lights, and trouble seeing at night

This may result in trouble driving, reading, or recognizing faces

Poor vision may also result in an increased risk of  falling and depression

Cataracts are the cause of half of  blindness and 33% of visual impairment worldwide
