PURPOSE: An eyeglass lens processing device is provided to measure the refraction surface shape of a lens using a simple structure, to provide a device at a low cost, and to process a lens with high precision. CONSTITUTION: An eyeglass lens processing device comprises a lens rotation unit, a first moving unit, a processing device rotation unit, a lens shape measurement unit (20), a second moving unit, and a control unit. The lens shape measurement unit measures the refraction surface shape of a lens on the chuck shaft of the lens. The lens shape measurement unit includes a measuring point which is in touch with the refraction surface. The second moving unit relatively moves the chuck shaft in a direction in which a distance between the chuck shaft and the measuring point is changed. |
