Abstract

A method of determining of user data for the production of an eyeglass lens for a selected eyeglass frame for a user. The method includes providing an eyeglass frame image data set of the selected eyeglass frame; gathering user image data at least of one portion of the user's head, together with at least one part of the selected eyeglass frame worn by the user; finding the pupils of the user in the user image data, and determining a pupil data set, said pupil data set comprising the size and/or the shape and/or the relative distance between the pupils of the user; and determining contour points of the rim of the eyeglass lens to be produced in the user image data, based on the eyeglass frame image data set and the pupil data set.
