ABSTRACT:
An apparatus for simulating an ocular optical system simulates a retinal image produced by a human eye through an optical lens. Optical system data are produced from an optical system including a cornea, a pupil, an intraocular lens, a retina, etc. Based on the optical system data, point spread functions each indicative of a distribution on an image plane of light emitted from a certain point are calculated by PSF (Point Spread Function) calculating means. Image data are subjected to convolutional integration with the point spread functions, determining retinal image data. The retinal image data are converted into display data, which are supplied to a display unit to display a retinal image thereon. The retinal image displayed on the display unit is an image that would be actually formed on the retina of the human eye, and provides an accurate objective indication of how the image is seen by the patient.
