Abstract

A method of calculating an individual progressive lens creates one or more basic designs for lenses based on theoretical specifications, and then creates starting designs from these basic designs. Individual progressive lenses are calculated from the starting designs corresponding to the individual data from wearing test subjects. Valid starting designs are then created for production. The individual lenses are calculated from the starting designs according to individual customer data.
