    摘要: A method for producing an ophthalmic lens comprised of a base lens and a film structure bound to said base lens includes a pressure-free heating. Said heating is performed after assembling the film structure with a semi-finished lens (1), and before said semi-finished lens is machined for obtaining the base lens. Although a maximum heating temperature is higher than a glass-transition temperature of the semi-finished lens, no image distortion and optical aberration is produced for the final ophthalmic lens. The maximum heating temperature is also lower than a glass-transition temperature of the film structure.

    摘要: A method for laminating a functional film on to an optical base element and a tri-layer adhesive system for use in the method. The tri-layer adhesive includes a first latex adhesive layer disposed on the functional film and a second latex adhesive layer disposed on the optical base element. An HMA layer is disposed in between the latex layers to form a tri-layer adhesive to permanently retain the functionalized film on the optical base element. The method includes first coating a latex adhesive on the functional film and second coating a latex adhesive on the optical base element. An HMA is then coated on to one of the dried latex adhesive layers. The film is hot pressed on to the optical base element with the HMA sandwiched in between the latex layers to form a laminated optical device.
