    Abstract: This invention relates to an ophthalmic lens comprising a substrate with a front main face and with a rear main face. said rear main face being coated with a multilayered antireflective coating comprising a stack of at least two layers having a refractive index higher than or equal 1.55, defined as “HI layer” and at least two layers having a refractive index lower than 1.55, defined as LI layer, characterized in that said multilayered antireflective coating is such that: —the mean reflection factor in the near infrared (NIR) region RmNIR is lower than or equal to 8% at an angle of incidence of 35°, and 10—the mean reflection factor RUV (280-380 nm). weighted by the function W(λ) defined in the ISO 13666:1998 standard, is equal to or lower than 5% at an angle of incidence of 35°.
