SCHEMATIC EYE FOR THE RAT

Previously published rat schematic eyes are shown to be inadequate and a new one is developed. It is demonstrated that a homogeneous lens is not satisfactory for modelling a small eye and a core lens model is provided. Attention is paid to the estimation of the confidence limits of the refractive state derived from the schematic eye computations. Other sections deal with peripheral aberrations, posterior nodal distance, exit and entrance pupils and the extent of the uniocular and binocular theoretical and observed visual fields of the rat. © 1979.
