A cataract can be caused from trauma, or more commonly, old age. A cataract is what occurs when your optical lens in your eye becomes so dense, that it cannot allow light to filter to your retinae, effectively making your vision dim and/or blurry.

The only effective means in removing a cataract, and therefore restoring vision, is surgery.

It is believed that cataracts come with age, and that if everyone lived long enough, everyone would develop one.
