Time Magazine coined the term op art in 1964, in response to Julian Stanczak's show Optical Paintings at the Martha Jackson Gallery, to mean a form of abstract art (specifically non-objective art) that uses optical illusions.[3][4] Works now described as "op art" had been produced for several years before Time's 1964 article. For instance, Victor Vasarely's painting Zebras (1938) is made up entirely of curvilinearblack and white stripes not contained by contour lines.
