What is op art most famous for?

Op art, short for optical art, is an art style that uses optical illusions to create a sense of movement, depth, or vibration. Op art is most famous for its use of bold colors, geometric shapes, and patterns that appear to change or move when viewed from different angles or distances. This effect is often achieved through the use of repeated lines, dots, or other simple shapes that create a sense of visual confusion or ambiguity. Op art is most commonly associated with the work of artists such as Bridget Riley, Victor Vasarely, and Richard Anuszkiewicz, who were prominent figures in the Op art movement during the 1960s and 1970s.
