摘要： The invention relates to a method for automatically centering an ophthalmic lens (10), comprising steps of: - positioning the ophthalmic lens on a holder, - acquiring at least one image of the ophthalmic lens received on the holder by means of a camera, and - processing said image to find the position of an optical center (P1) of said ophthalmic lens by means of a processing unit. According to the invention, said ophthalmic lens comprising several distinct centering markings (12) distributed along a geometrical figure, said step of processing comprises: - determining, for at least three of said centering markings, the position of at least one characterization point (P12) of each centering mark, and - deducing therefrom the position of the optical center of said ophthalmic lens.

摘要： A method of coating an edge surface (226, 224) of an optical lens (200) is provided. The method includes providing (401) an optical lens (200) comprising a first optical surface (220) and an opposing second optical surface (222), wherein the first and the second optical surfaces (220, 222) are connected by an edge surface (226, 224), disposing (402) at least one temporary protective material on at least a portion of a perimeter portion of one or both of the first and the second optical surfaces (220, 222) abutting the edge surface (226, 224), disposing (404) at least one coating material on the edge surface (226, 224) of the optical lens (200) to obtain at least one edge coating (202), and removing (4051, 4052, 4053) any excess coating material (204, 206) disposed on the at least one temporary protective material. An optical lens (200) having at least one temporary protective material disposed on only at least a portion of a perimeter portion of one or both of the first and the second optical surfaces (220, 222) abutting the edge surface (226, 224) is also provided.
