Abstract

A method for coating hydrogel and silicone hydrogel articles, and articles made by the method, are provided in which the coating is first applied to the molding surface in which an article-forming material will be cured to form the article. The method permits the thickness and uniformity of the coating to be more easily controlled than in known coating methods.
