Abstract
An object of the present invention is to provide single-lens type polarizing glasses which are optically sufficient in performance, and are rich in variety from a view point of design. Both of a polarizer of a right eye lens and a polarizer of a left eye lens can be two independent polarizing plates, both sides of which are protected with protective sheets, respective polarizing plates are bending-processed into a spherical, nonspherical or toric shape, and a backup resin is thermally adhered on the protective sheet on a concave side of the bending-processed polarizing plate to make a single-lens type polarizing lens, which is further prepared into single-lens type polarizing glasses.
