There is provided an eyeglass lens processing apparatus including a first rotational shaft which holds and rotates an eyeglass lens, a finishing tool, a chamfering tool which performs chamfering on an angular portion of an edge of the eyeglass lens, a second rotational shaft to which the chamfering tool is attached, an adjustment unit which adjusts a relative positional relationship between the first rotational shaft and the second rotational shaft, a chamfering angle setting portion which sets a chamfering angle formed between a rotational center axis of the first rotational shaft and a processing tool surface, an edge information acquisition portion which acquires information regarding an edge surface shape of the eyeglass lens, an angle correction portion which corrects the chamfering angle based on the information regarding the edge surface shape, and a control portion which controls the adjustment unit and performs chamfering based on the corrected chamfering angle.

A polishing device for optical elements includes: a tool shank (1), and a polishing disc base; wherein the tool shank (1) is connected to the polishing disc base and is mounted on a tool shaft of a numerical-controlled processing device; wherein a polishing film (3) is stuck on the polishing disc base; the polishing disc base is a profiling polishing disc base (7), a cylinder polishing disc base (2), a profiling polishing disc base (12) or a spherical polishing disc base (8); wherein the tool shank (1) is independent and universal, thereby reducing the processing cost of the polishing device. A polishing method for optical elements is based on the shapes mentioned above of the polishing disc base, including steps of: fixing a polishing disc connecting rod (11); sticking a polishing film (3); trimming the polishing film (3); and polishing an unprocessed work piece (6).

There is provided a circumference calculating device including an expected shape specifying part 201b configured to obtain an expected finish shape of a bevel in consideration of an interference amount of a beveling tool when beveling is performed to an uncut spectacle lens; and a theoretical circumference calculating part 201d configured to obtain a bevel circumference of the spectacle lens having the expected finish shape obtained by the expected shape specifying part 201b, as a theoretical circumference of this spectacle lens.

A spectacle lens processing device includes a drilling tool and a processor. The processor acquires a position of a hole formed in a lens and a pantoscopic angle. The pantoscopic angle is an angle in a vertical plane between a visual axis of a user and an optical axis of the lens when the user wears spectacles in which the lens after processing is mounted and faces forward. The processor determines, based on the acquired pantoscopic angle, a relative angle between the drilling tool and the lens when the hole is formed in the lens in the position of the hole.

Disclosed is a method of preparing an operation of surfacing of a lens blank to transform the lens blank into a generated lens having a predetermined prism corresponding to an inclination between a front surface and a back surface of the generated lens at least locally. The method includes: for a plurality of devices destined to interact with the lens blank during the operation of surfacing to manufacture the predetermined prism of the generated lens, attributing a priority order to each; based on the priority order, attributing to each device a prism portion which is zero or included in a respective range delimited by a respective minimum prism portion and a respective maximum prism portion, the prism portion representing contribution of the corresponding device to the prism of the generated lens, for further interaction of each device with the lens blank during the operation of surfacing.
