A transmissive optical device for enhancing human color vision, said device comprising:
- a substrate;
- one or more colorant layers applied at least one of onto and into the substrate, the one or more colorant layers including at least one colorant, the colorant created based on colorant-specific absorption spectra as defined by selected concentrations;
- and
- one or more thin film layers provided on the combined substrate and one or more colorant layers, the one or more thin film layers including materials creating thin film-specific reflectance spectra based on selected pluralities of materials each having their own respective refractive index,
- wherein the colorant-specific absorption, the thin film-specific reflectance and substrate cooperate to produce a static transmission spectrum of the optical device, wherein at least one of the one or more thin film layers and the one or more colorant layers cause the optical device to exhibit metamerism control such that the cosmetic tint of the static transmission spectrum of the optical device has a white point shift within 0.35 under every illuminant from the set of two or more illuminants and has a difference in lightness of less than 30 when the illuminant changes from one to another, wherein illuminants are selected from the pool of CIE, D55, D65, D75, F2, F7, F11 and L-series LED illuminants.
A method for creating an optical device to enhance human color vision, said method comprising:
- creating colorant-specific absorption spectra by selecting colorants, creating concentrations of the selected colorants, and creating one or more layers to contain the colorant;
- creating thin film-specific reflectance spectra by selecting a plurality of materials each having their own respective refractive index, selecting the number of layers in the thin film, creating each film layer;
- and
- constructing an optical device including the created one or more layers containing the colorant and the created film layers,
- wherein the colorant-specific absorption and the thin film-specific reflectance cooperate to produce a static transmission spectrum of the optical device, wherein the optical device exhibits metamerism control such that the cosmetic tint has a white point shift within 0.35 under every illuminant from the set of two or more illuminants and has a difference in lightness of less than 30 when the illuminant changes from one to another, wherein illuminants are selected from the pool of CIE, D55, D65, D75, F2, F7, F11 and L-series LED illuminants.
