Patent ID: 8534833

Claim:
An ophthalmic lens comprising a substrate with a front main face and a rear main face, the rear main face being coated with a multilayered antireflective coating comprising a stack of at least one layer having a refractive index higher than 1.6 and of at least one layer having a refractive index lower than 1.5 wherein: the mean reflection factor on the rear face in the visible region R m is lower than or equal to 1.15%; the mean light reflection factor on the rear face in the visible region R v is lower than or equal to 1%; the mean reflection factor R UV on the rear face between 280 nm and 380 nm, weighted by the function W(λ) defined in the ISO 13666:1998 standard, is lower than 5%, for an angle of incidence of 30° and for an angle of incidence of 45°; the multilayered antireflective coating comprises at least 3 layers; the multilayered antireflective coating does not comprise any layer with a thickness higher than or equal to 20 nm based on indium oxide; and the antireflective coating outer layer is a silica-based layer, wherein the mean reflection factor R UV on the rear face between 280 nm and 380 nm, weighted by the function W(λ) defined in the ISO 13666:1998 standard, is lower than or equal to 4%, for both an angle of incidence of 30° and an angle of incidence of 45°.
