  • Ophthalmic lens comprising a reflective anti-abrasion multilayer coating and process for manufacturing said lens
    Patent number: 10962689
    Abstract: The present invention relates to an ophthalmic lens (L6) comprising a substrate (1) having a front main face and a rear main face, the front main face being surmounted by a multilayer inorganic coating (2) that has an average luminous reflectance factor Rv in the visible equal to or higher than 4% and that consists of a stack comprising: at least two low-refractive-index layers that each consist of a first material of refractive index lower than 1.55, and at least one high-refractive-index layer that consists of a second material of refractive index higher than 1.55 and that is located between two said low-index layers that are adjacent in said stack, characterized in that said coating (2) has a thickness smaller than or equal to 600 nm and a Bayer ISTM abrasion-resistance value higher than 10.
