Abstract (en)

[origin: WO2006097606A1] The invention relates to a method of machining a face (3) of an ophthalmic lens (1), comprising: a main machining step in which the position of a machining tool (8) is synchronised with the angular position of the ophthalmic lens (1) which is rotated around an axis of rotation (4) that is transverse to the face (3), in order to provide the face with a machined surface that is asymmetrical in relation to the axis of rotation (4) of the ophthalmic lens (1); and a complementary machining step in which a recess (22) is machined around the axis of rotation (4) of the lens (1).
