Abstract: A method for drilling an ophthalmic lens (10) includes the following steps:—memorizing the desired shape and dimensions of a drill hole (701; 702; 703) to be drilled in the ophthalmic lens (10) and the position of the opening of this drill hole on one of the faces (11, 12) of the ophthalmic lens;—positioning a drilling tool (80) facing the memorized position of the hole to be drilled;—determining a control setpoint for the transverse movement and axial advance of the drilling tool; and—drilling the ophthalmic lens according to the control setpoint. The control setpoint for the transverse movement and axial advance of the drilling tool forces the point of this drilling tool, on at least one drilling run, to follow a helical or pseudohelical trajectory depending on the desired shape and dimensions of the drill hole. An associated drilling device is also described.

Abstract: Method for machining an optical surface of an optical lens, including: a lens blank providing step, during which a lens blank blocked on a lens blocker is provided; a clamping step, during which the lens blocker is clamped in a lens machining device; a tilting step, during which the lens blank and lens blocker are tilted relative to the rotation axis of the lens machining device; a surface position determining step, during which the position of the surface to be machined is determined based on the tilt angle of the lens blank and lens blocker relative to the rotation axis of the lens machining device; and a machining tool configuration step, during which the operational parameters of the lens machining tool are configured to manufacture the surface to be manufactured according to the determined surface position so the desired optical properties of the optical lens are respected.
