Abstract: Disclosed is a system for edging ophthalmic lenses, including: a first database table including first data relating to referenced eyewear frames; a second database table including second data relating to corrections to apply to the first data; and a processing unit suitable to calculate an edging setpoint as a function of at least a datum read in the first database table, corrected by a datum read in the second database table, the edging setpoint being suitable to be used by an edging machine to edge an ophthalmic lens along a final outline.

Abstract: A computer-implemented method for determining a dipping orientation of an ophthalmic lens (2) with respect to a dipping apparatus feature, the method comprising the step of: —determining a lens parameter relative to a shape of the ophthalmic lens (2): —determining said dipping orientation taking into account an interaction parameter representative of a relationship between said lens parameter and said dipping apparatus feature.

Abstract: Disclosed is a method for automatically centering an ophthalmic lens, including 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 the image to find the position of an optical center of the ophthalmic lens by means of a processing unit. According to the invention, the ophthalmic lens including several distinct centering markings distributed along a geometrical figure, the step of processing includes: —determining, for at least three of the centering markings, the position of at least one characterization point of each centering mark; and —deducing therefrom the position of the optical center of the ophthalmic lens.

Abstract: A method of coating an edge surface of an optical lens is provided. The method includes providing an optical lens comprising a first optical surface and an opposing second optical surface, wherein the first and the second optical surfaces are connected by an edge surface, disposing 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 abutting the edge surface, disposing at least one coating material on the edge surface of the optical lens to obtain at least one edge coating, and removing any excess coating material disposed on the at least one temporary protective material. An optical lens 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 abutting the edge surface is also provided.
