Abstract: Embodiments of the disclosure relate to primer compositions for increasing the adhesion between a polarizing film laminate to a cast-polymerized lens. The chemisorptive primers may react with cast-polymerized lens monomers and/or interact with the polarizing film laminate to provide exceptionally strong adhesion between the film laminate and the ophthalmic lens.

Abstract: Embodiments of the disclosure relate to an antistatic film structure which comprises a transparent antistatic support structure and at least one antistatic component. The transparent antistatic support structure and antistatic component may be combined by imbibing, melt extruding, blown film extruding, calendaring, solvent casting, mold casting, wet transfer, sublimation, and solidification of a liquid to a solid using heat, UV or other means.

Abstract: Disclosed are systems and processes for generating a finished or semi-finished lens, such as a spectacle lens, from a lens blank that includes an intermediate functional layer. Some embodiments of the process involve locating the functional layer and positioning the lens blank according to the location of the functional layer. The location of the functional layer can be ascertained by measuring the thickness of one or more layers of the lens blank. The lens blank can be surfaced on one or both sides to form a finished or semi-finished lens. Other embodiments are also described.

Abstract: An optical adhesive product and a process for manufacturing an optical adhesive product, laminated film ensembles, and laminated lenses. The optical adhesive product includes a glyoxal water solution that is pH adjusted for use as an optical adhesive that demonstrates a wet peel force strength above about 6 Newtons. A water based polymer, such as PVOH, may be added to the adhesive system. According to the process, the glyoxal adhesive system is manufactured and utilized to laminate TAC-PVA-TAC films together to form a polar film ensemble. The polar film ensemble is laminated to an optical substrate and in the case of an ophthalmic lens, surfaced, coated and edged. The optical adhesive product avoids film separation in the polar TAC-PAV-TAC film ensemble during edging.

Abstract: A polyurethane based adhesive containing one polyol compound derived from caprolactone monomer having a number average molecular weight between 200 and 1000 combined with a polyisocyanate compound. The functionality of the polycaprolactone polyol is between 1 and 4. Other aspects include a polarizing layered structure, a polarized lens and a method for manufacturing same all of which include the polyurethane based adhesive. The adhesive avoids delamination and is useful in optical applications where it will be in contact with water, for example during surfacing or edging process.
