what are cataracts?

Your eye’s natural lens sits behind the iris and pupil and works similarly to a camera lens.  This natural crystalline lens of the eye is clear and is primarily responsible for focusing light on the retina.  Any clouding of the natural lens is called a cataract.  Cataracts cause blurry vision that affects the person’s ability to see clearly and function effectively.

Cataracts occur most commonly as a result of age and everyone will eventually have cataracts if they live long enough.  Some people develop cataracts at a young age and these can be a result of heredity, trauma, diabetes and certain medications.
