Abstract
Some embodiments provide a lens including a lens body and an optical filter configured to attenuate visible light in certain spectral bands. At least some of the spectral bands can include spectral features that tend to substantially increase the colorfulness, clarity, and/or vividness of a scene. In certain embodiments, eyewear incorporates an optical filter that enhances chroma within one or more spectral bands. In some embodiments, a wearer of the eyewear can perceive the increase in chroma when viewing at least certain types of scenes.
Claims23
Eyewear, comprising:
- a lens comprising:
- a first lens element comprising glass;
- a second lens element comprising plastic;
- a polarizer separate from the first and second lens elements and disposed between the first lens element and the second lens element;
- wherein at least one of the first lens element, the second lens element or the polarizer comprises at least a portion of an optical filter comprising a chroma-enhancing material that increases an average chroma value of uniform intensity light stimuli having a bandwidth of 30 nm transmitted through the lens at least partially within a spectral range compared to a neutral filter that uniformly attenuates an equal average percentage of light as the optical filter within the spectral range;
- wherein the spectral range comprises at least one of 440 nm to 510 nm, 540 nm to 600 nm, or 630 nm to 660 nm;
- and
- wherein the average chroma value increase within the spectral range of 440 nm to 510 nm is greater than or equal to about 20%.
