    Abstract: Procedimiento para transferir un revestimiento sobre por lo menos una superficie geométricamente definida de un primordio de lente que comprende: - proporcionar un primordio de lente (1) que presenta por lo menos una superficie geométricamente definida (2); - proporcionar un soporte (5) que presente una superficie interna que sirve de apoyo a un revestimiento (6) y una superficie externa; - depositar sobre dicha superficie geométricamente definida de dicho primordio de lente o dicho revestimiento una cantidad previamente medida de una cola curable (4); - realizar un movimiento relativo entre sí del primordio de lente (1) y del soporte (5) o bien para llevar que el revestimiento (6) entre en contacto con la cola curable (4) o para que la cola (4) entre en contacto con la superficie geométricamente definida (2) del primordio de lente (1); - aplicar una presión suficiente sobre la superficie externa del soporte de modo que el espesor de una capa de cola final, después del curado, sea inferiora 100 micrómetros; - curar la cola; y - retirar el soporte (5) para recubrir el primordio de lente (1) con el revestimiento (6) adherido sobre su superficie geométricamente definida.

    Abstract: A radiation-curable coating composition for ophthalmic lens is disclosed which comprises a mixture of a monoepoxysilane, colloidal silica, an alkylalkoxysilane or tetraalkoxysilane, and an ultraviolet activated photoinitiator capable of initiating a cationic cure of such composition. The photoinitiator is an aromatic onium salt or an iron arene salt complex.

    Abstract: A process for applying a coated or uncoated film onto a surface of a lens substrate which comprises the steps of : providing a liquid hot melt adhesive (HMA) com-position comprising: a HMA base polymer and a polymerizable monomer or oligomer applying the liquid HMA composition onto either the surface of a film or a lens substrate drying the applied liquidHMA composition moving the film and the lens substrate rela-tively to each other to bring them into contact applying pressure on the film; heating to reach a Tmax process Temperature at or above the glass transition temperature (Tg), the monomers or oligomers being liquid at the Tmax process temperature and polymerizing the monomers or oligomers while maintaining pressure and heating.

    Abstract: A process for applying a coated or uncoated film onto a first main surface of a lens substrate which can be implemented in a short period of time without any risk of deformation of the lens substrate and which avoids overheating of a temperature sensitive coating borne by a second main surface of the lens substrate opposite to the first main surface. The process combines a unique heating and UV as an activation step for the adhesives. Also contemplated are lenses produced by the process.
