What term describes cloudiness of the crystalline lens?

Explanation:
Cloudiness of the crystalline lens is called a cataract. The lens normally remains clear to properly focus light on the retina, but when it becomes opaque, light transmission is reduced and vision worsens, often with glare and faded colors. Cataracts most commonly develop with aging, but can also be present at birth, or arise from injury, medications, or systemic diseases. This condition is distinct from glaucoma, which involves optic nerve damage from high eye pressure; retinopathy, which affects the retina's blood vessels; and astigmatism, which results from an irregular curvature of the cornea or lens that distorts focus.
