A human eye model based on anatomical data, which had been previously proposed by Hwey-Lan Liu, has been transformed into a new eye model considering the laminated structure of the lens. The anterior surface of the lens is prolate, whereas the posterior surface of the lens is oblate which is consistent with the anatomical data. A numerical program was written in C computer language to study the refractive structure of the eye and the optical characters of the model have been studied. The marginal wings appear in the longitude spherical aberration plot when the shell number is small, which means a lens with a small number of shells makes eyes a multifocal system. The result shows that eye with gradient-refractive-index-lens and that with shell-lens can get equivalent spherical aberration results.
