Dependence on angle and wavelength of light scattered by the ocular lens.
Asymptotic expansions of formal expressions for scattered light make explicit their dependence on scattering angle and wavelength. Such expansions are given for two cases of scatter geometry. In one case the source of scatter are assumed randomly positioned and randomly oriented. In the other case lens fibers, incorporated into a model of the crystalline lens fiber architecture, are the assumed sources of scatter. Calculated results based on scatter by lens fibers are in much better agreement with recent measurements on excised lenses (van den Berg, T.J.T.P. and Ijspeert, J.K., Light scattering in donor lenses. Vision Res. 35, 169-177, 1995) than those based on randomly positioned and randomly oriented scatterers.
