Abstract: A machine for transferring a preformed functional film onto a curved face of an ophthalmic substrate, including: a first device for receiving and holding the substrate; a second device for receiving the film, the first device and/or second device configured to hold the film by applying a pressure force to the periphery thereof; a first mechanism for moving the devices, configured to place the curved face such that it faces the film, a second mechanism for moving the devices, configured to bring into contact the center of the film with the center of the curved face and to apply the film with the substrate to radially spread, from the center of the film up to the periphery thereof, a conformal contact between the film and the curved face; and a control and command unit configured to control at least the second mechanism when the film and the substrate are in contact.

Abstract: The method includes the use of a closed mold consisting of two shells (2,3) and an annular joint (4), the joint having a hole (19) for filling the mold cavity with a polymerizable material, the introduction of the material occurring after a stage in which an external mechanical effort is exerted in order to bring the shells (2,3) together and before a stage in which the effort is relaxed. In the joint (4), the filling hole (19) includes two sections. A first section extends from the molding cavity to the second section which is wider. The device includes elements (34-40) for exerting an external effort in order to bring the shells (2,3) together and elements for introducing the polymerizable material into the molding cavity.
