Patent ID: 10823984

Abstract:
A polarizing element is superposed upon a lens base material. The polarizing element has an average light transmittance of light having a wavelength of 400 to 760 nm in a visible region is 30% or more. A light transmittance of light having a wavelength of 410 to 700 nm in a near infrared region is 0 to 2% when the polarizing element and an identical polarizing element are superposed one upon the other with their polarization axes perpendicular to each other. One of a film integral with the polarizing lens and the lens base material contains a near infrared ray absorption dye such that a light transmittance of light having a wavelength of 700 to 800 nm in a near infrared region is 0 to 2% when the polarizing lens and an identical polarizing lens are superposed one upon the other with their polarization axes perpendicular to each other.
