POLARIZING LENS AND METHOD FOR PRODUCING SAME

摘要

An aspect of the present invention relates to a method of manufacturing a polarizing lens, which comprises conducting curved surface processing to change a shape of a polarizing film into a shape of a curved surface, conducting heat treatment by heating the polarizing film that has been processed into a curved surface to a heating temperature of equal to or higher than 105°C but less than 150°C, assembling an upper mold, a lower mold, and a seal member to provide a casting mold having a cavity within which the polarizing film following the heating treatment is positioned, the upper mold and the lower mold being positioned opposite each other so as to sandwich the polarizing film at a space therebetween, and the seal member sealing the space between the upper mold and the lower mold, casting a curable composition into the cavity, curing the curable composition to provide a polarizing lens within which a polarizing film is positioned, and separating the polarizing lens thus provided from the casting mold.
