Abstract:
1. An eyeglass lens processing apparatus for processing a peripheral edge of an eyeglass lens, the eyeglass lens processing apparatus comprising: a processing unit including a lens chuck shaft for holding the eyeglass lens and a plurality of processing tools configured to process the peripheral edge of the eyeglass lens held by the lens chuck shaft; a calibrating lens; a mode selector configured to select a calibration mode; a memory configured to store calibration processing data for processing the calibrating lens to a predetermined shape; a detecting unit including a tracing stylus configured to contact a surface of the calibrating lens which is processed by the processing unit based on the calibration processing data to detect the shape of the processed calibrating lens in the calibration mode; and a calculating unit configured to obtain calibration data by comparing a detected result by the detecting unit with the calibration processing data in the calibration mode.
