(57) [Summary] [PROBLEMS] To be used for an eyeglass frame slightly inclined rearward and to be able to identify the thick end side in the manufacturing stage of anti-glare polarizing lenses having different thicknesses on the right and left for correcting the prism direction. To do. SOLUTION: A polarizing lens L is formed by fusing, polymerizing and integrating a polarizing element 1 with transparent plastic base layers 2, 3 interposed therebetween. A plastic film containing a dye such as iodine is stretched in a uniaxial direction to form a polarizing lens L by changing the thickness at both ends in the stretching direction of the molecularly-polarized polarizing element 1, and one end in the stretching direction is formed in a manufacturing step. The marks 5, 5 indicating that the thickness is larger than the other end are fused. |
