Claim Text:
1. 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 R the multilayered antireflective coating comprises at least 3 layers; the multilayered antireflective coating does not comprise any layer with a thickness higher than 15 nm based on indium oxide; the antireflective coating outer layer is a silica-based layer; and the mean spectral reflection factor on the rear face for at least one wavelength in the 280-295 nm range for both an angle of incidence of 30° and an angle of incidence of 45° is higher than 5%.
