PRODUCTION OF OPTHTHALMIC LENSES WITH PROTECTED MICROSTRUCTURES

摘要

A method for preparing ophthalmic lenses, which have a microstructure 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 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.

1. A method for manufacturing a spectacle lens, comprising:
providing a microstructure on at least one first surface of a spectacle lens body; and applying at least one protective coating on the spectacle lens body in such a manner that the protective coaling at least partially covers the microstructure, wherein the protective coating has a refractive index which differs from the refractive index of the spectacle lens body.
