Zusammenfassung:This invention relates to an ophthalmic lens with a low reflection in the ultraviolet region, comprising a substrate with a front main face and a rear main face, said 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 1.55, wherein: - the mean reflection factor R UV on said rear face between 280 nm and 380 nm, weighted by the function W(»), is lower than or equal to 5%, preferably is lower than or equal to 4%, for an angle of incidence of 35°, - the Chroma C* is equal or lower than 4, preferably lower or equal to 3, for an angle of incidence (¸) of 15°.
