Definition of Central vision
Central vision: A process in which millions of cells change light into nerve signals that tell the brain what the person is seeing. As a person reads, drives, and performs other activities that require fine, sharp, straight-ahead vision, light is focused onto the macula in the center of the retina, the light-sensitive layer of tissue at the back of the eye.
