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 … WebDec 17, 2024 · The integrated Stiles-Crawford function is commonly used as apodization model for vision through the natural eye pupil. However, this method does not account for possible effects related to the retinal thickness, the large length-to-diameter aspect ratio of the photoreceptors, or the use of nonMaxwellian illumination.
WebSep 2, 2008 · Stiles and Crawford proceeded to test whether their point-by-point curves, when integrated, would predict the original full-pupil reduction data. They did, to a reasonable degree of accuracy. Later research showed that, when subsidiary factors such as blur and aberrations are excluded, additivity holds to quite a high accuracy ( Enoch 1958 ). Stiles and Crawford subsequently measured this effect more precisely by observing the visual stimulus of narrow beams of light selectively passed through various positions in the pupil using pinholes. Using similar methods, the Stiles–Crawford effect has been verified by the scientific community. Observations See more The Stiles–Crawford effect (subdivided into the Stiles–Crawford effect of the first and second kind) is a property of the human eye that refers to the directional sensitivity of the cone photoreceptors. The Stiles–Crawford … See more Initially, it was thought that the Stiles–Crawford effect may be caused by the screening of light that passes near the edge of the pupil. This possibility was ruled out because … See more • Moon, Parry; Spencer, Domina Eberle (1944). "On the Stiles-Crawford Effect". Journal of the Optical Society of America. 34 (6): 319–29.
