Optical illusions Parallax and perception of distance.

(Parallax is the apparent displacement of an object when it is viewed successfully from two points not in the same line of sight. For example, read the speedometer from the front and from the passenger side. Two different speeds can be viewed. Parallax determines our ability to have depth perception.)
