  • Spectacle lens edging method
    Patent number: 8216024
    Abstract: A lens holder (16) is attached to a processing target lens (2) such that a holder center (O) coincides with a processing center position (21) of the lens. An axial deviation measuring mark (81a, 81b) is displayed on the processing target lens (2) to coincide with a reference position mark (80a, 80b) of the lens holder (16), and the circumferential surface of the processing target lens (2) undergoes primary processing. After primary processing, the axial deviation of the processing target lens (2) is measured from the reference position mark (80a, 80b) and axial deviation measuring mark (81a, 81b). When axial deviation exists, the lens holder (16) is removed from the processing target lens (2) and the processing target lens (2) is held again, so that the axial deviation is corrected. After that, the processing target lens (2) undergoes secondary processing.
