Paper Abstract

We compare the radial profiles of light pattern distributions formed in the retina and the exit pupil of a computational model eye, when the wavelength is varying. The computational eye simulates the presence of cataracts, as a particle distribution in the lens. We use three different wavelengths (400, 550 and 700 nm) for the incident light. The results show that for the shorter wavelength the effect of scattering is bigger around the center of the images while for the longest wavelength the light distribution is larger in the edges of the images. The distance from the center of the scattered light pattern to the zone where the profiles cross is inversely proportional to the size of the particles.
