Light and shadow perception
Cones that are stimulated by light send signals to the brain. The brain is the actual interpreter of color. When all the cones are stimulated equally the brain perceives the color as white. We also perceive the color white when our rods are stimulated. Unlike cones, rods are able to detect light at a much lower level.Yes, blind people can see light. Most blind people have some degree of light perception. How much light they can see, and where it is visible in their field of vision, varies from person to person.
