Abstract
The present invention relates to a method for manufacturing a polarized lens. In one embodiment, the method includes the steps of treating a polarized film with a composition to form a treated polarized film, providing a front lens mold having a concave surface with a curvature, spin-coating a hard coat composition onto the concave surface of the front lens mold to form a hard coat layer thereon, forming a first adhesive layer on the hard coat layer, placing the treated polarized film on the adhesive layer, curing the adhesive layer with UV or visible light to bond the treated polarized film to the hard coat layer, thereby forming a polarized front lens mold, and forming a polarized lens with the polarized front lens mold.
