Overview
A cataract is any clouding of the human lens. This clouding can cause a reduction in vision. The lens is composed of protein and water structured to allow light to clearly pass through. Changes to the structure of the protein result in a cataract. The changes in vision associated with a cataract depend upon which part of the lens is affected.
