Abstract

An eyeglass lens processing system, including: a data input unit, which inputs frame shape data for processing a lens to be fitted to an eyeglass frame and layout data for providing a layout of the lens with respect to a frame shape; a lens processing unit, having two shafts for clamping the lens, for grinding a periphery of the lens; a first conveying unit, which conveys a tray on which the lens is placed and to which a management code is applied, the management code interrelating the lens placed on the tray to the data inputted by the data input unit; a lens measuring unit, which obtains at least an optical center position of the lens; a second conveying unit that picks and holds the lens, disposes the lens at a predetermined position of the lens measuring unit, and mounts the lens to the shafts of the lens processing unit after measurement by the lens measuring unit; and an arithmetic unit, which obtains processing data based on: (1) data, read out based on the management code applied to the tray from the data inputted by the data input unit, and (2) measurement data obtained by the lens measuring unit, the arithmetic unit being connected to the lens processing unit.
