WebThe story of the Stiles-Crawford Effects begins in 1933 with the experiments of STILES and CRAWFORD (1933) in which they investigated subjects’ responses to light striking the retina at varying angles of incidence. For example, in Fig. 1(a) the subject compares rays a and b striking his fovea. The angle of incidence θ between a ray and the normal to the retina and …

W. Stanley Stiles and B.H. Crawford studied the phenomenon in which measured brightness decreases as light enters farther from the center of the pupil. (See the figure.)
