Why do your eyes change colors when you go blind?

Blind: They don't always change color when a person goes blind, but an opaque cornea will turn the front of the eye white. Also, cataract can turn the pupil dark yellow, brown, or white. Are you blind? Did someone tell you that your eye color changed?

Depends on cause: of the blindess. Not being able to see doesn't cause color changes. The disease that created the blindness can cause color changes. Most apparent would be a disease of the cornea, which often causes it to turn white.
