Abstract

The invention relates to a method, a computer program product and a system for designing or producing a spectacle lens for a spectacle wearer. Said method consists of the following steps: individual user data or application data of the spectacle wearer is obtained; the design concept for the spectacle lens having a plurality of evaluation points is determined; a main beam path through the plurality of evaluation points is determined; a local wavefront is specified for each of the main beams in the surroundings of the respective main beam; optical properties of the spectacle lens are determined on the evaluation points by determining an influence of the spectacle lens on the local wavefronts in the surroundings of the respective evaluation point; and the design concept is evaluated in accordance with the determined optical properties and the individual user data.
