Abstract: A method is implemented by a computer for modifying a non-dioptric parameter of an optical system including a first and a second surface. The method includes a modifying step during which the first surface and second surface are modified so as to obtain a modified optical system such that the dioptric function of the modified optical system is substantially the same as the dioptric function of the optical system.

Abstract: A method for checking the compliance of a checked optical characteristic of a checked ophthalmic lens (30) relative to an expected optical characteristic, from a non-deformed pattern (40) and a deformed pattern (20) each having a non-uniform contrast, the method includes the steps of: a) determining (A) an image pattern (50), which is the image of the deformed pattern through the checked ophthalmic lens, in predefined optical conditions, b) combining (B) the image pattern with the non-deformed pattern to form a test pattern (60), c) comparing (C) the test pattern with at least one reference pattern (70), and d) deducing (D) the compliance of the checked optical characteristic with the expected optical characteristic on the basis of the preceding comparison. A device for implementing such a checking method is also described.

Abstract: Disclosed are eyeglasses adapted to a wearer, including two half-frames interconnected by a bridge, each half-frame including at least a branch and an ophthalmic lens. The bridge of the eyeglasses is made of a separated element attached to each of the half-frames, the bridge having at least one geometrical feature determined by taking into account a morphologico-geometric parameter of the wearer. Also disclosed is a kit and a method for manufacturing the eyeglasses and a method for ordering the eyeglasses.

Abstract: Method implemented by computer means for controlling a manufacturing device used in an optical lens manufacturing process. 1 Optical lens data is provided, wherein the optical lens data represents the nominal and effective values of at least one optical lens parameter of an optical lens manufactured according to a manufacturing process using a manufacturing device. Manufacturing data is provided identifying at least the manufacturing device used to manufacture the optical lens. The difference between the nominal and effective values of the at least one optical lens parameter of the optical lens is determined. A recommended value of a manufacturing parameter of the manufacturing device identified by the manufacturing data is determined, wherein the recommended value of the manufacturing parameter is determined based on the difference between the nominal and effective values of the at least one optical lens parameter.
