What is a cataract? Who is at risk for developing them?
A cataract is a cloudy area in the normally clear lens in the front of the eye. Cataracts are caused by a chemical change of unknown origin in the eye, and cause blurred or distorted vision. People at risk for developing cataracts are over 55 years old, have had eye injuries or disease, have a family history of cataracts, smoke cigarettes or use certain medications.
