Abstract

A model of human eye for experiments in vision research has been developed using PLZT ceramics. This “artificial eye” allows to simulate light scattering caused by cataract in the eye lens. Light scattering of a composite eye lens of the model depends on the electric field applied to a transparent electrooptic PLZT ceramics plate that is attached directly to the lens. The image degradation in such a model eye at various degrees of scattering is studied observing and recording the contrast of images on the ‘’retinal plane” created by standard test objects with different spatial frequency or by a He-Ne laser source passing a diffractive transparent placed before the eye.
