The contribution of the cornea and the crystalline lens to the longitudinal chromatic aberration (LCA) of the human eye at different pupil diameters was investigated numerically. Two different functions were used to approximate corneal shape. Crystalline lens was represented by hundreds of shells with refractive indices increasing from the cortical to the inner shells. Lenticular shells had a form of semi-ellipsoids joined smoothly at the equator. A computer-modelling program was used to simulate refraction through the systems considered. Introducing dispersion of the elements of the eye the longitudinal chromatic aberration has been calculated. It appeared that LCA of both the cornea and the crystalline lens, and consequently, of the whole eye depends on the diameter of the input beam. Calculations showed that the crystalline lens was more dispersive than cornea.
