Optical element or polarizing plate, and eyewear using same

An eyewear lens comprising an optical element, wherein the optical element has a side that receives incident light from an external light source and an eyeball side, and comprises a polarized light-emitting element and an absorption polarizing element, wherein the polarized light-emitting element comprises a first substrate comprising a polarized light-emitting pigment, the first substrate being supported by a first support that does not contain an ultraviolet absorbent, the first support being on said side that receives incident light from the external light source;

• wherein said polarized light-emitting element polarizes and emits light in a visible region and is laminated with the absorption polarizing element that comprises a second substrate and is supported by a second support that contains an ultraviolet absorbent, and absorbs and/or reflects light in the visible region, and wherein the order of lamination, from the side that receives incident light from the external light source to the eyeball side, is (1) the first support, the polarized light-emitting element, the second support, and then the absorption polarizing element;
• or (2) the first support, the polarized light-emitting element, the absorption polarizing element, and then the second support, and wherein the polarized light-emitting element has an absorption wavelength of 350 to 380 nm.
