A lens for reducing glare and improving color discrimination includes a lens wafer containing a rare earth oxide such as neodymium that provides progressively higher transmittance at 540 nm than at 500 nm and at 450 nm, and average transmittance at 540 and 610 nm that is greater than the transmittance at 580 nm. A ultra-violet absorber, a polarized filter and anti-reflective layer may be included to reduce UV light, glare and improve contrast and vision.
