Abstract:
Provided is a spherical or aspherical polarized mirrored glasses lens that substantially prevents the appearance of reflections caused by reflection from the mirrored surface, has a high transmittance, and with the use of a colored absorption-polarization film layer, allows arbitrary selection of the color of the field of view of the sunglasses user and the color of the lens as seen by others. A polarized mirrored glasses lens is fabricated, said lens being characterized by having, in order from the light-incidence side, at least a reflection-polarization film layer and an absorption-polarization film layer, and further characterized in that: the transmission axes of said layers are aligned; and the light-incidence side is a convex spherical or aspherical surface.
