  • Patent number: 9475242
    Abstract: An eyeglass lens processing apparatus includes a lens chuck unit that holds an eyeglass lens; a processing unit that has a processing tool to process the eyeglass lens held by the lens chuck unit; and an adjustment unit that adjusts a relative distance between the eyeglass lens and the processing tool. The eyeglass lens processing apparatus operates the processing unit and processes the eyeglass lens by operating the adjustment unit based on processing data. The eyeglass lens processing apparatus includes a check unit that checks whether or not the eyeglass lens is properly processed in a state where the eyeglass lens is held by the lens chuck unit.
