The Blind Spot
Captions available
The idea
The blind spot is the region of the retina where the optic nerve exits and no receptors are present.
In practice
With one eye closed, a small mark at a certain position vanishes entirely from the visual field.
Where people slip
The gap is not perceived as a hole. The visual system fills it with surrounding pattern.
