Abstract

The present work aims at introducing a computer model that reconstructs the visual system of the human eye. The model considers that the lens is composed of a core and peripheral layers of different indices of refraction and curvatures. The adjustment of the dimensions of the lens is assumed to take place under constant volume conditions. The model employs a ray tracing technique, so that it follows the incident rays to its final destination on the retina. The results showed that the received image on the retina takes the same curvature, such that the curved images is highly focused
