A member asked:
What is the medical term for when your blind and can only see black and white?
A doctor has provided 1 answer
Light perception: If the vision has dropped to the point that the eye can only detect light and dark, then we call that light perception only. We do discriminate in that some can tell what direction a light might be aimed at the eye and we call that light projection which is localization or directional sensitivity which indicates a little better function than light perception only.
