Optical op art would typically fall under the category of “visual art” or “fine art,” specifically within the subcategory of “abstract art” or “contemporary art.” This classification reflects its status as a style of art that primarily focuses on visual elements and techniques to create optical illusions and engage the viewer’s perception. Within the broader category of visual art, optical op art may also be considered a subset of “Op art,” a movement that emerged in the 1960s and encompasses various artists and artworks that employ optical illusions.
