  • Optical article comprising a multilayer anti-reflective coating and method of production thereof
    Patent number: 8142896
    Abstract: The invention relates to an optical article, for example, an ophthalmic lens, comprising at least one multilayer anti-reflective coating on a transparent substrate made from organic or mineral glass. Said coating comprises successively and starting at the substrate, a layer of material with high refractive index (HI), made from a hybrid organic/inorganic matrix within which are dispersed particles of mineral oxide or chalcogenide with a diameter of 2 to 50 nm and a layer of material with low refractive index (BI), obtained by hardening of a composition comprising at least one silane precursor (I) with 4 hydrolysable groups and at least one fluorosilane precursor (II), said second composition comprising at least 10% in mass of fluorine in a theoretical dry extract and with a molar ratio I/I+II greater than 80%.

  • Ophthalmic lenses comprising a photodegradation protection coating and a process for producing such lenses
    Patent number: 7815308
    Abstract: The present invention relates to an optical article, in particular an ophthalmic lens comprising a substrate, a coating that includes at least one photodegradation-sensitive dye, and a photodegradation protection (anti-UV) coating for protecting the coating containing at least one photodegradation-sensitive dye, the photo-degradation protection coating comprising a blend of acrylate oligomers and monofunctional or multifunctional acrylate monomers, at least one UV absorber and at least one photoinitiator. This anti-UV coating used is particularly suitable for an ophthalmic lens in which the polarizing function is provided by a bilayer system, one layer of which comprises liquid crystals combined with dyes, and more particularly dichroic dyes. Advantageously, the anti-UV coating according to the invention is combined with an oxygen barrier layer.
