1. An optical element for correcting visual insensitivity between a first visible color wavelength and a second visible color wavelength, comprising:
a substantially transparent matrix material; a luminescent compound dispersed within the substantially transparent matrix material, wherein the luminescent compound has an emissive wavelength that substantially overlaps with the first visible color wavelength; wherein the luminescent compound comprises a perylene derivative dye; and wherein the perylene derivative dye is represented by a formula: wherein R1 and R1′ are independently hydrogen, C1-C10 alkyl, C3-C10 cycloalkyl, C2-C10 alkoxyalkyl, C6-C18 aryl, or C6-C20 arylalkyl; m is 1, 2, 3, 4, or 5; and n is 1, 2, 3, 4, or 5. |
