The present invention is drawn to a method for providing an optical article, such as an ophthalmic lens, with a topcoat, comprising: (a) activating the surface of an outermost organic coating of said article with vacuum air plasma, (b) optionally depositing a specific bond coat composition onto said activated surface, so as to obtain a bond coat, and (c) coating the activated surface of the outermost organic coating, or the bond coat if present, with said topcoat composition so as to form a topcoat, preferably an anti-fouling or anti-fog topcoat. |
