A process of organic vapor deposition for significantly improved corrosion protection of metal. The process involves deposition of a thin film by polymerization of certain precursors onto the surface of a metal phosphate treated metal substrate (15). A primer or topcoat is subseqently applied over the metal substrate.

A fixture device and method for uniformly and efficiently treating an article in a gaseous atmosphere. The fixture device provides a plurality of point contact support locations for supporting the article during the treatment. The fixture device and treatment method are especially useful in the plasma treatment of contact lenses to improve surface biocompatibility and hydrophilicity.

The invention is concerned with the problem that with known plastic casting moulds, especially those of polypropylene, the lenses produced with these moulds have a slippery surface. The invention solves this problem through the use of polymers which are notable for their very low oxygen permeability.

An apparatus and method for the production of ophthalmic lenses, and particularly contact lenses, which minimizes damage of the lens in removal from the mold. The ophthalmic lens is produced in a mold having a male part and a female part that are placed in proximate relation to each other to create a lens-forming cavity. At least the female surface of the female part mold is preferably coated with plasma and is irradiated for a predetermined time such that the female surface and/or surface coating is at least partially cured. Once the female surface, and alternately the male surface and other surfaces of the mold, is at least partially cured, a curable lens-forming material is placed into the lens-forming cavity and cured to form an ophthalmic lens.
