An eyeglass lens processing apparatus includes: a processing apparatus body for processing a lens, which includes a grinding water supply unit for ejecting grinding water to a portion to be processed of the lens; a centrifugal separator which separates processing refuse from grinding water by rotating a dewatering bin to discharge the grinding water to the outside of the dewatering bin; and a calculation control unit which includes a counter for multiplying a processing refuse amount of the lens on the basis of a control signal of the apparatus and a memory for storing a processing refuse extraction reference provided to maintain filtering efficiency of the dewatering bin, the processing refuse extraction reference being determined on the basis of the multiplied processing refuse amount of the lens, and which generates an alarm signal when the multiplied processing refuse amount of the lens reaches the processing refuse extraction reference.
