  • 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.

  • SPECTACLE LENS WITH REDUCED FRICTION PROPERTIES, MEASUREMENT METHOD FOR DETERMINING THE SMOOTHNESS OF THE SPECTACLE LENS AND METHOD FOR PRODUCING THE SPECTACLE LENS
    Publication number: 20250067999
    Abstract: The present invention relates to a spectacle lens having a substrate and a functional coating arranged as the outermost layer on the substrate, wherein the functional coating imparts to the spectacle lens a haptic smoothness coefficient HGK of at most 0.28, preferentially at most 0.25, and/or a haptic smoothness coefficient R_HGK of at most 0.85, preferentially at most 0.80. The present invention furthermore relates to a measurement method for determining the smoothness of a spectacle lens, which is expressed by the haptic smoothness coefficient HGK and/or the haptic smoothness coefficient R_HGK, as well as to a method for producing the spectacle lens.
