Op Art (short for Optical Art) is a form of abstract geometric art that developed in the 1960s. The purpose of Op Art is mainly to challenge the viewer through optical illusions, usually in black and white compositions.

Victor Vasarely’s paintings are considered to be the first early examples of Op Art, and specific works such as Zebra (1937), a black and white composition that gives the impression of a three-dimensional image.
