An eyeglass lens processing apparatus comprising a processing control unit which performs polishing by controlling a lens rotating unit, a grindstone rotating unit and an axis-to-axis distance varying unit based on an input target lens shape so as to process a periphery of a lens, which has been finished, by a lens margin allowed for polishing by the polishing grindstone. The processing control unit controls the lens rotating unit, the grindstone rotating unit and the axis-to-axis distance varying unit based on a lens rotating speed V1 and the grindstone rotating speed Vw at least at the final rotation of the lens. The lens rotation speed V1 and the grindstone rotation speed Vw satisfy a condition in which an average interval between cyclic stripes appearing on a processed surface of the lens due to height fluctuations of the polishing grindstone is smaller than eye's resolution or is larger than 2 mm.
