Paper Abstract

Optical models of crystalline lens were analyzed, to increase understanding of high transparency and loss of it with aging and for pathology tissue. Experimental and calculated human crystalline lens spectra in a wide range of wavelengths are presented. Calculations were made for the model of short-term- order scatterers, taking into account interference effects of scatterers and specific features of absorbing species, such as protein-bound tryptophan, kynurenine, and age-related chromophores leading to generalized yellowing of the lens proteins. Satisfactory qualitative coincidence of calculated spectra with spectrophotometric data for isolated human lens is shown. Measured angular dependencies of scattering matrix elements are sensitive to modification related to aging and cataract appearance.
