Abstract:
This invention relates to an ophthalmic lens with a low reflection both in the ultraviolet region and in the visible region, comprising a substrate provided on its rear main face with a multilayered antireflective coating (3-7 layers) comprising a stack of at least one layer with a high refractive index and at least one layer with a low refractive index, having a mean reflection factor on the rear face in the visible region R m  lower than or equal to 1.15%, a mean light reflection factor on the rear face in the visible region R v  lower than or equal to 1%, a 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, lower than 5%, for angles of incidence of 30° and 45°, the antireflective coating outer layer being a silica-based layer. The lens according to the invention does especially prevent the reflection of the UV radiation produced by light sources located behind the wearer.

Claim (Index 31):
The lens of  claim 15 , wherein the mean reflection factor R UV  on the rear face between 280 nm and 380 nm, weighted by the function W(\u03bb) defined in the ISO 13666:1998 standard, is lower than or equal to 4%, for both an angle of incidence of 30\u00b0 and an angle of incidence of 45\u00b0.
