Abstract: The present invention relates to a new ocular lens made of a composite material for optical use, as well as its method of production. This material consists of a substrate (1) having a convex face facing the observer on which is deposited a layer (2) of anti-scratch varnish, and a concave face facing the wearer on which are deposited successively a layer (3) of anti-scratch varnish, a layer (4) made of a metallic film, a layer (5) made of precious metal, a layer (6) made of a metallic film, a metal oxide layer (7), a layer (8) of a metallic film and a layer (9) of metal oxide. Application to solar or ophthalmic lenses or shields.

Abstract: A new method for partial silvering of spectacle lenses, and lenses obtained using said method. Applied to spectacle lenses comprising a varnished substrate on which one or several thin layers are arranged, uses a digitally controlled laser, said laser emitting through a solid fiber, the wavelength used being in the near infrared. When these lenses comprise three thin layers it is possible, by using the method according to the invention, to achieve partial silvering in which the laser has eliminated: the thin layers on a first part thereof, until reaching the varnished substrate, then the thin layers on a part thereof, revealing a part of the thin layer, and lastly the thin layer, on a part thereof, revealing a part of the thin layer.
