It is formed by molding it into the shape of a piece of eyeglasses with a width of about 180 to 200 mm. The left and right polarizing plates in polarized glasses are arranged so that their light absorption axes (arrows) intersect. As a result, each polarizing plate predominantly transmits images for the right eye or left eye, thereby enabling stereoscopic viewing. From the viewpoint of visibility, the preferred arrangement is to have the light absorption axes of the polarizing plates orthogonal to each other for the images for the right eye and for the left eye, especially at an angle of 45 degrees with respect to the horizontal direction. It is preferable to arrange the light absorption axes so that they are orthogonal to each other at a corner. The above arrangement is applicable whether a polarizing plate is used only for the lens portion or when the entire lens portion is formed from a polarizing plate.

なし眼鏡とすることができる。The polarized glasses for stereoscopic images of the present invention are made by permanently deforming a plastic laminated thin plate into a curved state. The permanent deformation imparted is a curved shape that generates stress that can pinch the face when bent back in the direction of flattening. The shape of the curve is determined as appropriate, and generally, as shown in FIG. 3, the entire body is uniformly curved, or as shown in FIG. The flat plate may have a curved shape, or a flat plate with only both ends curved. This curvature makes it possible to wear the glasses on the face as shown in FIG. 5, making it possible to obtain vineless glasses.

A method in which a polarizing plate formed into a prescribed eyeglass shape is wound around a core of a constant diameter and then heat treated, or a method in which a polarizing plate formed in a prescribed eyeglass shape is heated through a heating roll etc. and then wound around the core. etc. In addition, when forming the whole with a polarizing plate, the method of applying tension when sticking a polarizing film to a support film and curving a polarizing plate based on the internal distortion can also be used. In the case of the former core winding method, the appropriate diameter of the core used is 20 to 50 mm. Therefore, the polarized glasses of the present invention can also be configured in a rolled state based on curvature.
