    IPC: G02B1/11

    Abstract: The present invention relates to an optical article having anti-reflectio n properties and high thermal resistance, comprising a substrate having at l east one main face coated with a multi-layer anti-reflection coating compris ing a stack of at least one high refractive index layer and at least one low refractive index layer, wherein the ratio:RT sum of the physical thicknesse s of the low refractive index layers of the anti-reflection coating/sum of t he physical thicknesses of the high refractive index layers of the anti-refl ection coating is higher than 2.1. If the anti-reflection stack comprises at least one low refractive index layer having a physical thickness >=100nm which is not the outermost layer of the anti-reflection coating, said relat ively thick layer and the underlying layers are not taken into account in RT calculation.

    Abstract: The invention concerns a method for making an antiglare stack by vacuum evaporation on an organic substrate ( 1 ) at a temperature lower than 150° C., comprising steps which consist in depositing at least a layer of material having a refractive index different from that of MgF 2 ( 4, 4 '), preparing the surface of the thus coated substrate, and depositing an outer MgF 2 layer ( 5 ) without ionic assistance. The resulting antiglare stack on organic substrate exhibits good adherence and good scratch resistance. The invention is applicable to ophthalmic lenses.

    IPC: G02C7/10 ,  G02B27/00

    Abstract: 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.
