Rarely, cataracts can present at birth or in early childhood as a result of hereditary enzyme defects, and severe trauma to the eye, eye surgery, or intraocular inflammation can also cause cataracts to occur earlier in life.
The cataract is a lens that has become clouded. Cataracts occur when there is a build-up of protein in the lens that makes it cloudy. This prevents light from passing through a normally clear lens, causing some loss of vision. No one knows what causes the build-up of protein responsible for clouding the lens.
