Coating reducing the reflexion for a fully transparent optical element, made of organic material, for example a spectacle glass. The coating reducing the reflexion comprises a plurality of layers of which at least one is a metal oxide. In an embodiment of the present invention, at least one layer is comprised of erbium oxide, terbium oxide, dysprosium oxide or holmium oxide. In another embodiment there is provided a layer of samarium oxide, europium oxide, neodymium oxide or ytterbium oxide of a thickness comprised between lambda /10 and lambda /20. In a third embodiment, an yttrium oxide layer is metallized under vacuum to a silicon dioxide layer which is directly applied to the optical element made of organic material. |
