Cataract refers to which of the following changes?

Cataract is the clouding of the eye’s lens caused by changes in the lens proteins that decrease its clarity. The lens normally stays transparent so light can be focused on the retina; when these proteins clump or degrade, the lens becomes opaque, scattering light and blurring vision. This is a problem of the lens itself, not of the iris, cornea, or retina. For contrast: inflammation of the iris is iritis, infection of the cornea is keratitis, and degeneration of the retina affects the back layer of the eye.
