    Abstract: A process is provided where at least one main face of an optical lens is subjected to a corona discharge or atmospheric plasma treatment. The optical lens is dipped in a curable coating composition to deposit a layer of the curable coating composition on said main face, and is then cured. During the whole process, the optical lens is carried by a same lens holder so that the lens face is freely accessible and without necessitating manual handling of the lens.
