Optical article comprising an antireflective coating in the visible region for low luminance conditions

Abstract

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 multilayered antireflective coating has: a mean light reflection factor in the visible region for photopic vision Rv lower than or equal to 2.5%, preferably lower than or equal to 0.9%, for at least an angle of incidence lower than 35°; a mean light reflection factor in the visible region for scotopic vision Rv′ lower than or equal to 0.5%, preferably lower than or equal to 0.4%, for at least an angle of incidence lower than 35°.
