An optical adhesive product and a process for manufacturing an optical adhesive product, including laminated film ensembles, and laminated lenses, are described. 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 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, when forming an ophthalmic lens, surfaced, coated and edged. The optical adhesive product avoids film separation in the polar TAC-PAV-TAC film ensemble during edging.
