METHOD FOR THE ADDITION OF A FUNCTIONAL COATING ON AN OPTICAL SURFACE OF A SPECTACLE LENS SUITABLE TO BE ARRANGED IN A SPECTACLE FRAME

摘要

The invention proposes a method for the addition of a functional coating on an optical surface of a spectacle lens suitable to be arranged in a spectacle frame, said method comprising the following steps: - providing a first set of rules suitable to determine if the features of an optical surface chosen within a list of features are compatible with a functional coating chosen within a list of functional coatings, and a second set of rules to determine a modified optical surface if features of an optical surface and a functional coating are not compatible; - providing said spectacle lens; - choosing within the list of functional coatings a functional coating to be added on said optical surface; - analysing the quality of the optical surface and identifying the features of the optical surface; - determining (118) thanks to the first set of rules if the features of the optical surface and the chosen functional coating are compatible; - if the optical surface has features compatible with the chosen functional coating, depositing (120) the chosen functional coating on the optical surface; - if the optical surface has features not compatible with the chosen functional coating, forming (128) a modified optical surface which is compatible with the chosen functional coating determined thanks to the second set of rules and depositing (120) the chosen functional coating on the modified optical surface.
