Zusammenfassung:This invention relates to an ophthalmic lens comprising a transparent substrate with a front main face and with a rear main face, at least one of the main faces being coated with a multilayered antireflective coating comprising a stack of at least one layer having a refractive index higher than or equal 1.5 and at least one layer having a refractive index lower than 1.5, such that:-the mean light reflection factor in the visible region Rv is lower than or equal to 0.5% for an angle of incidence lower than 35°;-the Chroma C* is equal or higher than 18, preferably 20, according to the international colorimetric CIE L*a*b* for an angle of incidence (Θ) of 15°.
