Polarized lens with oxide additive

Abstract

A lens for reducing glare and improving color discrimination includes a lens wafer containing a rare earth oxide such as neodymium that provides relatively high light transmittancy at 450 nm, 540 nm, and 610 nm, and relatively low light transmittency at 500 nm and at 580 nm. A polarized filter is included to reduce glare, and an anti-reflective layer minimizes ghost images, haze, and loss of contrast.
