Implementations described and claimed herein provide systems and methods for adding a chosen functional coating on an optical surface of a spectacle lens. In one implementation, it is determined if identified features of the optical surface of the spectacle lens are compatible with the chosen functional coating according to a first set of rules. The features of the optical surface are identified based on an analysis of a quality of the optical surface. Manufacturing information for the chosen functional coating is generated based on the determined compatibility. The manufacturing information includes information for depositing the chosen functional coating on the optical surface where the identified features are compatible with the chosen functional coating and on a modified optical surface where the identified features are not compatible with the chosen functional coating.

Method for the addition of a functional coating on an optical surface of a spectacle lens suitable to be arranged in a spectacle frame

The invention concerns a method for making an antiglare stack by vacuum evaporation on an organic substrate () at a temperature lower than 150&#xb0; C., comprising steps which consist in depositing at least a layer of material having a refractive index different from that of MgF('), preparing the surface of the thus coated substrate, and depositing an outer MgFlayer () without ionic assistance. The resulting antiglare stack on organic substrate exhibits good adherence and good scratch resistance. The invention is applicable to ophthalmic lenses.

Cold antireflection layer deposition process

This invention features a thin film polarization splitter, its manufacture and ophthalmic lens with projection inserts containing it.
