This invention is to provide an inexpensive lens can be worn without attention to the existence of the addition power segment of conventional polarizing lens, it and a bench lens are formed integrally on the rear surface of a polarizing member. The present inventors constituent a polarizing memberby sandwiching poly vinyl alcoholas a polarizing film with poly carbonatewhose both surfaces are stretched, and mold resin' on the rear side of the polarizing member, and arrange an addition power segmentintegrally on the rear surface, make the molded resin poly carbonate sandwiches the polarizing film. The top and the bottom of this member are cut as FIGs. to form lens at low costs, and the adhesion among respective resins is increased, and to secure the impact resistance and it is possible to create a lens without detachment because of same resin.
