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).
