  • Publication number: 20260036832
    Abstract: A method for applying a pattern on a spectacle lens substrate is disclosed. The method produces a low contact angle surface on a preselected part of a surface of the spectacle lens by plasma treating a preselected part of an uncoated surface of the spectacle lens substrate. Subsequently, a hard coating composition and optionally a primer coating composition are applied to the spectacle lens substrate.

  • Patent number: 10185057
    Abstract: Coated articles are provided comprising: (a) a substrate; (b) a porous sol-gel layer superimposed on at least one surface of the substrate; wherein the porous sol-gel layer comprises a hydrolyzed tetraalkoxysilane; and (c) a sealant layer superimposed on at least one surface of the porous sol-gel layer; wherein the sealant layer comprises an alkyltrihalosilane. The coated articles demonstrate superior abrasion resistance due to a glass-like layer formed from the combination of the porous sol-gel layer and sealant layer.
