Abstract

An eyeglass lens processing apparatus for processing a peripheral edge of an eyeglass lens, includes: a processing unit including a plurality of processing tools that process the peripheral edge of the eyeglass lens held by a lens chuck shaft; a calibrating lens; a mode selector that selects a calibration mode; a memory that stores calibration processing data for processing the calibrating lens to a predetermined shape; a detecting unit that includes a tracing stylus that contacts 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 that obtain calibration data by comparing a detected result by the detecting unit with the calibration processing data in the calibration mode.
