Abstract:
An eyeglass lens processing apparatus is provided with: a lens chuck shaft that holds an eyeglass lens; and a beveling tool for forming a bevel on the periphery of the lens. The beveling tool includes a first processing part for forming a rear bevel on the lens rear side; and a second processing part for forming a bevel foot coupled to the rear bevel. In the second processing part, the distance from a line parallel to the lens chuck shafts and passing through a point of border with the first processing part gradually increases from the point of border as the starting point to the endpoint of the second processing surface and the increase rate of the distance gradually increases at least in two steps toward the endpoint.
