Abstract
A method of manufacturing a polarizing lens for spectacles in which the lens is obtained by injection co-molding the material of the lens on a polarizing optical filter structure is described. The optical filter structure which already has its curved shape received during the stage of filter manufacture is subjected to a thermoforming stage before being inserted into the injection mold in order that the optical filter should obtain the desired curvature for the subsequent stage of injection co-molding the lens onto the optical filter structure.
