Color Perception Mechanisms and Binocular Vision

Jan 10, 2020




You can sensitize your retina by closing your eyes and resting your cones (remember when you close eyes a long time and open them you seem to be blinded first). When you open your eyes shortly (seconds) and look at some bright object the cones get excited. When you close your eyes again the cones will not desensitize and will stay stimulated longer and give you a positive afterimage.
