Method and Apparatus for Processing Coated Spectacle Lenses

Abstract

By means of the method and the apparatus in accordance with the invention, coated spectacle lenses are processed to form at the latter joining surfaces which permit a reliable adhesive bonding of the lenses to the bridge and the lugs of rimless spectacles. The method provides that for the respective spectacle lens two processing areas are predetermined with the shape, size and location thereof at the lens and that in the two predetermined processing areas the coating at the lens is locally removed by irradiation by a laser beam. The apparatus excels by a holder including at least one mount for a lens, a laser beam device including a laser head for generating a laser beam, a positioning device for moving the holder and the laser head relative to each other in a reference plane and a control means wherein for the laser beam device and the positioning device, wherein the laser power, the relative position between the laser head and the at least one lens as well as a scanning motion of the laser beam are controllable by the control means wherein.
