Abstract: The present invention is directed to a process for coating at least one geometrically defined surface of an optical article's substrate, without generating optical defects, said surface forming a Fresnel lens (2), comprising: providing a removable plastic carrier (4) having a specific thickness and a specific base curvature, depositing a curable coating composition (3) onto either the at least one surface forming a Fresnel lens or the internal surface of the carrier, moving the carrier and the optical article relatively to each other to bring the deposited curable coating composition into contact with either the at least one surface forming a Fresnel lens or the internal surface of the carrier, applying a specific pressure onto the external surface of the carrier to spread out the curable coating composition so as to cover said at least one surface forming a Fresnel lens, curing the layer of curable coating composition and withdrawing the removable carrier.
