Optical Model of the Human Eye

This eye model (based on the work of Navarro) uses a spherical retinal surface as well as a thin lens defocusing element.
Move the red locator button to position the light source and the blue one for rotation.

Based on I. Escudero-Sanz and R. Navarro, "Off-Axis Aberrations of a Wide-Angle Schematic Eye Model," J. Opt. Soc. Am. A, 16(8), 1999 pp. 1881-1891.
This sample optics Demonstration was created using Optica 3, an application package available for Mathematica.
In the program, the thin lens defocusing element is governed by the input defocus parameters and (in diopters). The defocus angle determines the angle of rotation (in degrees) about the pupil center for the defocus effects. The scatter parameter is used to specify the diffuseness of the retina. The pupil size parameter determines the diameter of the pupil opening. Spatial units are in millimeters.
