Abstract: A method for manufacturing an ophthalmic lens including selecting a base of polymeric material and applying a multiple layer structure coating. The coating is selected by designating an interphase, a first layer (of 91-169 nm) with a refraction index higher than 1.8, a second layer (of 128-248 nm) with a refraction index lower than 1.65, a third layer (of 73-159 nm) with a refraction index higher than 1.8 and a fourth layer (of 40-138 nm) with a refraction index lower than 1.8. A total thickness of the multiple layer structure is less than 600 nm. The structure has intermediate layer(s) with intermediate refraction indices, wherein a doublet of two adjacent layers that fulfil the thicknesses above is replaced by a triplet so that the thickness and an optical thickness of the triplet differ from those of the doublet by less than 5%, respectively.

Abstract: Lens comprising a polymeric substrate, a hardening layer and a metallic layer. Lens comprising a substrate of polymeric material (P), and which is coated with a hardening layer (E) and a metallic layer (M) that is between 1 and 20 nm thick. The coating also has an anti-humidity layer (AH) made of a material from the group made up of ZrO2, Nb2O3, Ta2O5, CeO2, HfO2, La2O3, TiO2, Pr2O3, Sc2O3, WO3, Y2O3, ZnS and the combinations thereof, that is between 35 nm and 55 nm thick, where between the anti-humidity layer (AH) and the hardening layer (E) there is no other sandwiched layer that is thicker than or equivalent to the anti-humidity layer (AH). Over the metallic layer (M) there is a first high refraction index layer (A1), and a first low refraction index layer (B1).
