    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.

    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.

    Inventor： GLACET ARNAUD ,  JIANG PEIQI ,  WEBER STEVEN

    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.
