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.

First claim

The invention claimed is:

1. A polarized mirrored glasses lens, which has, in order from a light incidence side, at least
a colored absorption-polarization film layer (A);
a reflection-polarization film layer (B); and
an absorption-polarization film layer (C),
wherein only an adhesive layer exists between said colored absorption-polarization film layer (A) and said reflection-polarization film layer (B),
wherein only an adhesive layer exists between said reflection-polarization film layer (B) and said absorption-polarization film layer (C),
wherein the transmission axes of said reflection-polarization film layer (B) and said absorption-polarization film layer (C) are aligned,
wherein the light incidence side is a convex spherical or aspherical surface, and
wherein the transmission axes of said colored absorption-polarization film layer (A) and reflection-polarization film layer (B) being aligned.

2. The polarized mirrored glasses lens according to claim 1 , wherein a
transparent thermoplastic resin film or
sheet layer

is laminated, via an adhesive layer, on
the light emission side of the absorption-polarization film layer (C) or
the light incidence side of the colored absorption-polarization film layer (A), or both.

3. The injected polarized mirrored glasses lens according to claim 1 ,
wherein a transparent thermoplastic resin film or sheet layer is arranged on the light emission side of the absorption-polarization film layer (C), and
wherein a layer made by injection-molding a transparent thermoplastic resin is integrated into the surface thereof of said transparent thermoplastic resin film or sheet layer.

4. The injected polarized mirrored glasses lens according to claim 2 ,
wherein the transparent thermoplastic resin film or sheet layer is arranged on the light emission side of the absorption-polarization film layer (C), and
wherein a layer made by injection-molding a transparent thermoplastic resin is integrated into the surface thereof of said transparent thermoplastic resin film or sheet layer.
