    摘要: Disclosed is a method for manufacturing an ophthalmic lens including a substrate and a functional film securely fastened to a curved face of the substrate. This method includes a method for gluing the initially flat functional film to the curved face. To ensure that the functional film when securely fastened to the curved face filters a preset band of wavelengths centered on a wavelength denoted λp, multiple functional films are preselected; two knowledge bases are established experimentally; a film is selected, using the two knowledge bases, from the plurality of preselected films, the wavelength λi′ on which is centered the band of wavelengths that this film filters for a certain degree of deformation being equal to λp when the degree of deformation is that given for the curvature in question; and the gluing method is implemented in order to securely fasten the selected film to the curved face.

    摘要: The present invention is drawn to an optical article comprising: (a) a transparent optical polymer substrate, (b) a transparent intermediate abrasion-resistant coating obtained from at least one epoxysilane by a sol-gel process, and (c) a transparent outer coating comprising a polythiolene matrix obtained by curing a liquid monomer mixture comprising at least one polyfunctional thiol and at least one polyfunctional allyl monomer, said cured polythiol-ene matrix having a glass transition temperature comprised in the range from 40° C. to 70° C. and a thickness from 3.5 μm to less than 10 μm. It is also drawn to a method for preparing such an optical article and to a method for repairing scratches in such an optical article by heating.
