摘要：This invention relates to the preparation of molds for the production of contact

lenses and other ophthalmic articles. By using an inorganic material to coat the opticalsurfaces and sidewalls of mold parts made from clear-resin materials, manufacturers canproduce lens molds with greater dimensional stability and chemical resistance. In additionto protecting the clear resin from interaction with otherwise reactive monomers fromwhich the molded article is made, such coatings can also be used to achieve preferentialrelease of the molded article. The resulting mold is especially useful for providing aneconomical way to improve manufacturing quality of contact lenses.
