Abstract: A laminated optical lens having an edging-optimized laminar configuration and method for manufacturing same. The laminated optical lens includes an optical base lens and a film layered structure including an external film furthest from said lens. An adhesive layered structure is placed between the film layered structure and the optical base lens so as to permanently retain the film layered structure on the surface of the optical base lens. The laminated lens is manufactured by laminating a film layered structure having an external film to an optical base element with an adhesive layered structure. The external film has a thickness of at least 100 μιπ, and preferably a thickness in the range of 150 microns to 300 microns inclusive. The adhesive layered structure has a thickness in the range of 5 microns to 100 microns inclusive, and preferably of 25 microns to 50 microns inclusive

Abstract: Disclosed are methods for preparing a laminate incorporable to a surface of an optical lens. A front surface and/or back surface of a photochromic film or a functional film is pre-treated. A second thermoplastic film is then laminated on each pre-treated surface of the photochromic film or functional film using a water-based adhesive. The pre-treatment applied on the surface(s) of the photochromic film or functional film enables the formation of strong adhesion between the second thermoplastic film and the water-based adhesive.

Abstract: A polarizing structure comprising a polarizing film, a protective film provided on at least one face of the polarizing film with an adhesive layer which is a glyoxal-based adhesive or a water based polymer adhesive such as a PVOH-based adhesive layer, and wherein at least one face of said protective film oriented towards said polarizing film further comprises an adhesion primer structure. The adhesive avoids delamination of the polarizing structure, which withstands edging processing conditions, and which also show excellent dry peel force. Other aspects of the invention relates to a method for manufacturing such a polarizing structure, and a polarized ophthalmic lens comprising such polarizing structure.
