Blind artists are people who are physically unable to see normally, yet work in the visual arts. This seeming contradiction is overcome when one understands that only around 10% of all people with blindness can see absolutely nothing at all. As such most blind people can in fact perceive some level of light and form, and it is by applying this limited vision that many blind artists create intelligible art. Also, a blind person may once have been fully sighted and yet simply lost part of their vision through injury or illness. Blind artists are able to offer insight into the study of blindness and the ways in which art can be perceived by the blind, in order to better improve art education for the visually impaired.
