ABSTRACT:
An eyeglass lens processing apparatus for processing a lens to fit the lens into a rim, includes: an edge measurement portion that measures a path of an edge position of the chucked lens based on a 2-D outline shape is a projection shape of the rum in its warp direction and a layout of the optical center of the chucked lens; and an arithmetic operation portion that obtains an inclination angle of the edge path or a temporary bevel path obtained based on the edge path with respect to a center axis, obtains a corrected 2-D outline shape which is a projection shape onto a plane perpendicular to the center axis based on the inclination angle and the 2-D outline shape, and obtains a final bevel path to form a bevel in the periphery of the lens chucked at the optical center based on the corrected 2-D outline shape.
