A cataract is a clouding (opaque area) over the lens of the eye. This area is normally clear (transparent).
Cataracts keep light rays from passing through the lens and focusing on the retina. The retina is the tissue lining at the back of the eye that’s sensitive to light. This may happen when the protein that makes up the lens gets cloudy. This affects your child’s vision.
Cataracts are rare in children. They can affect one eye (unilateral) or both eyes (bilateral).
Some cataracts are small and don’t cause any trouble with vision. Other, more progressive cataracts can cause visual problems in children.

Cataracts in children can cause blindness if they aren't treated.
