Abstract
An apparatus and method for displaying a difference in the Abbe number of an ocular optical lens to facilitate visual appreciation and understanding of the difference by a layperson. The apparatus and method indicates a degree of chromatic aberration at each point of a spectacle lens by inputting data corresponding to an Abbe number and outputting a representation of a region of comfortable vision. A plurality of the data may be obtained using a plurality of spectacle lenses having different Abbe numbers. On a single screen, the invention displays an image of the shape of a spectacle frame, a plurality of regions of comfortable vision (as a circle, ellipse or another closed curve, for example) and the difference in vision due to the difference in the Abbe number is evaluated from the display.
