The blind spot is not a black coin pasted into vision. Binocular overlap explains much of its invisibility: the fellow eye usually sees the corresponding region. But the one-eye demonstration reveals more. Even without the second eye, people often perceive a continuation of surrounding colour, texture or contour. Researchers call this perceptual filling-in, and the literature warns against reducing it to one “brain guesses” mechanism.
