Method of determining parameters for adding frames to an ophthalmic lens

摘要

The method involves providing a spectacle frame (10) such as closed or semi-opened frame, that includes a temporal part (113) equipped with a groove (11) to permit the fitting of ophthalmic lens. A shape of a profile of the groove is determined in a point of the temporal part of the frame, and compared with a data base. A determination is made whether the frame is issued from the deformation of groove thread on bolus or the deformation of the thread with three-dimensional strapping machine.
