Abstract

Human visual perception is very complex. Under various circumstances we come across a number of unusual visual phenomena. Some of these are utilised by magicians to mesmerise audiences. Several scientists, such as Purkinje, Bezold–Brücke, Helmholtz–Kohlrausch, Hunt, Stevens, Helson–Judd, Bartleson–Breneman and Stiles–Crawford, have explained a few such unusual phenomena, which are discussed in this chapter. Types, causes and tests of colour blindness are explained.
