The invention relates to a polymer lens comprising a hardening layer, an absorbent layer, and an interferential multilayer, and to a corresponding production method. Said polymer lens comprises a hardening layer, an interferential multilayer, and an absorbent layer there between. The absorbent layer is formed from a metal, a metal oxide or a metal nitride that can produce a transparent layer by means of sputtering deposition, and also comprises cations of a colouring metal of the group formed by the transition elements that, in an oxidised form, have a cation that absorbs electromagnetic radiation in the visible spectrum. Between 10 atom % and 70 atom % of the cations, in relation to the predominant metallic cation in said absorbent layer, are said colouring metal cations. |
