Optical article comprising an antireflective coating with a low reflection both in the ultraviolet region and in the visible region

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 refractive index is expressed at a wavelength of 550 nm,
• the mean reflection factor RUV 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 both an angle of incidence of 30° and for an angle of incidence of 45°;
• the multilayered antireflective coating comprises at least 3 layers;
• wherein
• (a) 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%, or
• (b) the mean spectral reflection factor on the rear face over at least 70% of the 280-290 nm wavelength range, for an angle of incidence of 15° is higher than 10%.
