First Claim
Patent Images
1. A device for improving color discernment comprising:
- an optical element comprising a luminescent compound in a substantially transparent matrix;
wherein the optical element absorbs light in a wavelength range near peak sensitivity for an M human cone photopigment and emits light of a longer wavelength in a wavelength range near peak sensitivity for an L human cone photopigment; and
wherein the optical element has a median wavelength of visible absorption, an average wavelength or visible absorption, or a peak wavelength of visible absorption of about 510 nm to about 550 nm.
