The present invention relates to an apparatus for producing a polarized lens that is used to prevent glare due to light, more particularly polarized light to form an inclined groove that is the polarizing film is installed on the inner surface of the gasket, which is installed the upper mold and the lower mold a gap preventing wrinkling of the round of the film caused by large, and the upper and lower surfaces of the upper mold and a gasket which the lower mold is installed to form a plane and a curved surface which is generated between the gasket and the upper mold, a gasket and a lower mold removed relates to a polarizing lens manufacturing apparatus with reduced defects in the polarizing lens due to clearance in manufacturing the polarizing lens. These polarizing lens manufacturing device according to the present invention is a gasket made of a synthetic resin or rubber material of the soft, and install the mold to the bottom, the phase, and installing the polarizing film between the bottom of the mold, formed by the molds installed in the gasket in the raw material for manufacturing the lens according to the inner space in the polarizing lens manufacturing apparatus for manufacturing a polarizing lens, Wherein in the same direction on one side of the gasket to be on the lens for producing the raw material in the inner space formed raw material inlet and the air outlet port, wherein the upper portion of the projection, the top mold top surface seated formed inside the gasket is formed, the lower There is a lower mold is formed with a lower surface that is seated, the inclined insertion groove for installing the polarizing film to the upper surface the lower side are formed, and forms a plane in the lower part, which contact with the upper surface of the projecting portion of the upper mold, two axial grooves for the polarization axis display show in the polarizing film is used alone, the movement of the raw material and the inside air. Polarizing lens, a polarizing film, a gasket, molded
