Abstract

An eyeglass lens processing apparatus includes: lens rotating means for rotating a lens chuck shaft; chuck shaft moving means for moving the lens chuck shaft; a processing tool that processes a lens; axis-to-axis distance changing means for changing a distance between the lens chuck shaft and the processing tool; lens shape measuring means including a tracing stylus holding unit that holds a tracing stylus contacting the lens to be movable in the axial direction of the lens chuck shaft and detecting means for detecting a movement position in a direction of the lens chuck shaft of the tracing stylus; lens moving means for relatively moving the lens in a direction in which a distance between the lens chuck shaft and the tracing stylus is changed; and controlling means for controlling the lens rotating means and the lens moving means based on a target lens shape, and controlling the chuck shaft moving means so that the movement position in the direction of the lens chuck shaft of the tracing stylus is in a predetermined range during measurement of a shape of the lens.
