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.
