Eyewear with chroma enhancement

A lens for an eyewear, comprising:

• an optical filter having a spectral absorptance profile configured to increase an average chroma value of uniform intensity light stimuli transmitted through the optical filter within a first filtered portion of a visible spectrum and within a second filtered portion of the visible spectrum, a chroma value being a C* attribute of a CIE L*C*h* color space,
• wherein the increase in average chroma value comprises an increase compared to a neutral filter that uniformly attenuates a same average percentage of light as the optical filter, within a bandwidth of each light stimulus;
• wherein the first filtered portion comprises a spectral range from about 465 nm to about 475 nm;
• and
• wherein the second filtered portion comprises a spectral range from about 540 nm to about 565 nm.

A lens for an eyewear, comprising:

• an optical filter configured to provide a spectral absorptance profile to increase an average chroma value of uniform intensity light stimuli transmitted through the optical filter in a first filtered portion of a visible spectrum and to decrease the average chroma value in a second filtered portion, a chroma value being a C* attribute of a CIE L*C*h* color space,
• wherein the increase in average chroma value comprises an increase compared to a neutral filter that uniformly attenuates a same average percentage of light as the optical filter, within a bandwidth of each light stimulus;
• wherein the first filtered portion comprises a spectral range from about 625 nm to about 655 nm;
• and
• wherein the second filtered portion comprises wavelengths greater than about 660 nm.

A lens for an eyewear, comprising:

• an optical filter comprising one or more chroma enhancement windows and one or more transmission windows, wherein the optical filter is configured to increase a chroma value in the one or more chroma enhancement windows and to transmit light in the one or more transmission windows,
• wherein the increase in chroma value comprises an increase compared to a neutral filter that uniformly attenuates a same average percentage of light as the optical filter, within a bandwidth of each light stimulus;
• wherein a first transmission window comprises a spectral range from about 440 nm to about 460 nm;
• and
• wherein a first chroma enhancement window comprises the spectral range from about 465 nm to about 475 nm and a second chroma enhancement window comprises the spectral range from about 540 nm to about 565 nm.
