摘要：This invention relates to the preparation of molds (10) for the production ofcontact lenses and other ophthalmic articles. By using an inorganic material to coat theoptical surfaces (2, 3) and sidewalls (12, 13) of mold parts (6, 7) made from clear-resinmaterials, manufacturers can produce lens molds (10) with greater dimensional stabilityand chemical resistance. In addition to protecting the clear resin from interaction withotherwise reactive monomers from which the molded article (8) is made, such coatings(11) can also be used to achieve preferential release of the molded article. The resultingmold (10) is especially useful for providing an economical way to improve manufacturingquality of contact lenses.
