Abstract
A method for determining an electronic spectacle frame element of a spectacle frame, including providing electronic element data relating to an electronic element to be embodied in a spectacle frame element; providing predetermined spectacle frame element data related to at least one geometrical parameter of a predetermined spectacle frame element, corresponding to the wearer demand; defining a working electronic spectacle frame element including a working spectacle frame element and an electronic element embodied in the working spectacle frame element based on the electronic element data, modifying the working electronic spectacle frame element, and determining the electronic spectacle frame element by repeating the modifying step so as to minimize the difference between the geometrical parameters of the predetermined spectacle frame element and the working spectacle frame element.
