Abstract: A method and apparatus for simulating an ocular optical system that enables simulating visual perception having fluctuation, distortion and blur in the use of spectacle lenses such as progressive addition lenses. A binocular synkinetic rotation-based retinal image is created, defined as an image obtained by rotating both eyeballs toward each object point in a visual field, then, uniting images projected on the foveae of right and left eyes and to produce a united image. An original image is created wherein the midpoint of binocular rotation is placed at a specific position, and objects within a specific pyramidal visual field are observed. A distorted original image is obtained by observing the visual field through spectacle lenses using the ray tracing method. Point Spread Functions (PSF's) are derived, wherein right and left monocular PSF's are obtained and a united binocular PSF is derived from both monocular PSF's.
