Blind Spot Demonstration

Description
To find your blind spot, close your left eye and, with your right eye, fix your gaze on the + in the green square. Slowly move the page toward you. When the page is approximately 6 inches away, you will notice that the black dot on the right disappears because of your blind spot. Not only does the black dot disappear, but its vacancy is replaced by yellow: The brain “fills it in” for you.
