Définition et Signification de "op art"

What is "optical art"?

Optical art, commonly known as op art, is an art movement that began in the 1960s, focusing on creating visual effects that play tricks on the viewer's eyes. Artists like Bridget Riley and Victor Vasarely used patterns, shapes, and contrasting colors to create illusions of movement, depth, and vibrations on a flat surface. The art often appears to be shifting or pulsing when looked at, making it a unique experience that challenges the viewer's visual senses. Op art is about involving the eye and mind, exploring how visual elements can create the sense of motion and dimension without actually being present.
