  • Method for compensating positioning errors in an edging process, or in a fastening operation for a raw-edged, finished spectacle lens, and device therefor
    Patent number: 12246409
    Abstract: The invention relates to a method for compensating positioning error in an edging process or in a fastening operation for a raw-edged, finished spectacle lens, the method comprising: —determining centring deviation parameters, said centring deviation parameters indicating the occurrence of positioning errors for the raw-edged, finished spectacle lens during a fastening operation and/or during a subsequent edging process, and—modifying control information with the aid of the determined centring deviation parameters such that the positioning errors for the raw-edged, finished spectacle lens are compensated and/or taken into account. The invention also related to a corresponding device.

  • Method and device for checking the centering of at least one spectacle lens
    Patent number: 11221505
    Abstract: In a method for checking the centration of at least one spectacle lens, the spectacle lens is arranged in a field of capture of an image capturer; at least one image of the spectacle lens is captured by means of the image capturer; and positions of functional engravings of the spectacle lens in the captured image are determined. Furthermore, at least one lens contour of the at least one spectacle lens in the captured image is determined and the centration of the spectacle lens is checked taking into account the determined positions of the functional engravings, the determined lens contour and a known, wearer-dependent target geometry of the centration.
