Abstract (en)

[origin: WO2014037915A1] The invention relates to a method for preparing a spectacle frame (1) adapted to a face, the spectacle frame (1) having a bridge (11) between two optical lenses (9-10) and a surface (2) having end pieces (5-6) to which temples (3-4) are connected, which method includes the following steps: providing an image of the face; identifying the characteristic points on the image of the face; identifying shape points on the image of the face; identifying the shape of the face from among predefined characteristic shapes using said shape points; determining from said characteristic points a frame of reference for receiving the surface of the spectacle frame; and determining the height position and width of the end pieces relative to the surface of the spectacle frame depending on the face shape identified.
