Doss, J D

A computer program (LENS* 4) has been written that may be used for ray-trace calculations of human or animal eyes. The user enters all relevant eye specifications, and the program calculates ray segments from a (specified) external object. From the ray calculations, the program yields data on image location, image distance from the retina, retinal spot size, and effective pupil diameter. The program also allows entry of simple corrective lens systems that simulate a contact lens or ordinary spectacles. Graphics output illustrating the eye cross section, corrective lens, and rays is provided either on the CRT, thermal printer, or graphics plotter. Although the program is written in BASIC, many of the statements (particularly in the graphics section) are peculiar to the Hewlett-Packard 9845B desktop computer.
