Visual impairment in art is a limited topic covered by research, with its focus being on how visually impaired people are represented in artwork throughout history. This is commonly portrayed through the inclusion of objects such as canes and dogs to symbolize blindness, which is the most frequently depicted visual impairment in art. Many notable figures in art history, such as Leonardo da Vinci, Claude Monet, and Georgia O'Keeffe, were visually impaired, or theorized to be so.
