Disclosed is a polarizing, transparent optical product, the structure of which comprises a basic transparent substrate of an inorganic or organic material and, on at least one part of the external surface of said basic substrate, a polarizing coating. Said polarizing coating is fixed, in a stable manner, to said substrate and has a stratified structure which includes: a polymer layer, which is fixed to the external surface of said substrate, directly or via a coupling under-layer; a film of colorant(s) having polarizing properties, on said polymer layer; and a protective layer on said film of colorant(s). Also disclosed is a method of manufacturing such a polarizing, transparent optical product. The invention may be used for any type of substrate material, inorganic or organic, thermoplastic or thermoset.
