    摘要： The invention relates to a method for producing a photochromic plastic article, comprising the steps: (a) applying a layer comprising monomers, which are suited for forming a polymer, in liquid form and at least one photochromic colorant to at least one area of the inner surface of a first casting mold (GF1), which is situated in a casting packet, and partially or completely hardening the layer while forming a photochromic polymer layer (3); (b) optionally applying a protective layer (2) to the partially or completely hardened photochromic polymer layer (3) and hardening the protective layer (2); (c) pouring a casting resin (1) into the casting packet, which comprises the first casting mold (GF1) that, together with a second casting mold (GF2), forms a predetermined cavity inside the casting packet, and; (d) hardening the casting resin (1) while forming a photochromic plastic article. The invention also relates to a photochromic plastic article that can be obtained by using this method.

    摘要： The present invention relates to a method for preparing ophthalmic lenses (10), which have a microstructure (18) on at least one side, particularly a diffractive microstructure for colour fringe correction, wherein the invention provides in particular a method which substantially reduces any adverse effect on the microstructure by damage or soiling during the manufacture of an ophthalmic lens and during the use thereof. Thus a method according to the invention for manufacturing an ophthalmic lens comprises provision of a microstructure on at least one first surface of an ophthalmic lens glass and application of at least one protective coating (20) on the ophthalmic lens glass in such a manner that the protective coating at least partially covers the microstructure, wherein the protective coating has a refractive index which differs from the refractive index of the ophthalmic lens glass.
