摘要: This invention relates to an ophthalmic lens comprising a transparent substrate with a front main face and with a rear main face, at least one of the main faces being coated with a multilayered antireflective coating comprising a stack of at least one high refractive index layer (HI) having a refractive index higher than or equal to 1.55 and at least one low refractive index layer (LI) having a refractive index lower than 1.55, characterized in that: said at least one high refractive index layer (HI) is in direct contact with said at least one low refractive index layer (LI) forming a bilayer, said bilayer has a physical thickness lower than or equal to 60 nm, said bilayer is, in the direction moving away from said transparent substrate, in second to last place in said multilayered antireflective coating, said multilayered antireflective coating has a mean reflection factor Ruv between 280 nm and 380 nm, lower than 5% for an angle of incidence in the range from 20° to 50°.

摘要: This invention relates to an ophthalmic lens comprising a transparent substrate with a front main face and with a rear main face, at least one of the main faces being coated with a multilayered antireflective coating comprising a stack composed of at least: (i) a wetting layer; (ii) a metal layer, wherein the metal is selected from silver, gold or copper or mixtures thereof; (iii) a protective layer which is able to avoid oxidation of said metal layer, characterized in that wetting layer (i) is in direct contact with metal layer (ii), with the proviso that said multilayered antireflective coating does not comprise silicon nitride and wherein (ii) the metal layer has a physical thickness equal to or higher than 6 nm.
