Optical illusions are always deceptive. The information about a particular object is gathered by the eyes and the brain receives the information to process them. When the information is processed, the image that is perceived by us does not match with the physical dimensions of the actual object. Optical illusions have been sparking interests in many people since centuries. Many popular artists, scientists and people from other fields have taken immense interest in different types of optical illusions. Art Optical illusion is a type of optical illusion that is based on mathematics. To have Art optical illusion, patterns of moiré are created by using the repetition of form and color. Many artists who have used the optical illusions in their creations have created the images using the black and white paints only. When the viewers look at such images they can see hidden images, three dimensional forma, movements, different types of stimulation and confusion in the foreground as well as in the background of the image. Psychologist William Orbison had described the Orbison illusion in 1939. In this Art Optical illusion, the inner square seems to be distorted because of the radiating line but the actually it is an image of a perfect square. Another famous Art optical illusion is the Hering illusion that was discovered in 1851.

Stare at the picture with concentration and figure out whether the lines are curved or is it just an illusion created because of the circles.
