Optical Illusion, Young vs. Old, 1888(18 of20)
Open Image ModalAnonymous German postcard from 1888. A famous perceptual illusion in which the brain switches between seeing a young girl and an old woman. An optical illusion is a phenomena where one seems to see something that doesn\'t exist or with another perspective. It is also called visual illusion and is categorized by visually apparent images. An optical illusion is basically a visually misleading image interpreted by the brain inaccurately. There are three main types: literal optical illusions that create images that are different from the objects that make them, physiological ones that are the effects on the eyes and brain of excessive stimulation of a specific type (brightness, color, size, position, tilt, movement), and cognitive illusions, the result of unconscious inferences.

Optical Illusion, Rubin's Vase, 1915(19 of20)
Open Image ModalRubin\'s vase is a famous set of ambiguous or bi-stable (i.e., reversing) two-dimensional forms developed around 1915 by the Danish psychologist Edgar Rubin. We see the image: either as two white faces looking at each other in front of a black background, or as a black vase on a white background. The shape of the image depends on the side of the line we chose as part of the figure. This is important because the human brain has in general just one object in the field of perception and the other objects go into the background of perception. The reversal you perceive may happen because you shift your attention from one contour to another or from one color to another. (credit:New York Public Library via Getty Images)
