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.

Abstract: Eyewear comprising an integrated camera module including a point-of-view camera is disclosed. The camera module can be connected to the eyewear lens and supported exclusively by the eyewear lens.

Abstract: The present disclosure provides dyed articles comprising a polymer resin and a) a first dye that provides peak infrared absorption in the range of between about 900 nm and about 1100 nm in the resin and b) a minus-violet dye. The present disclosure also provides minus-violet dyes according to Formulae II and III, and methods of making the minus-violet dyes.

Abstract: Chroma-enhanced eyewear lenses (eyewear including sunglasses, goggles, visors, etc.) are comprised of absorbing species, including dyes, that selectively attenuate visible light transmission at one or more wavelength bands, and thereby influence the perception of color and impart a chroma enhancement effect. Chroma-enhanced lenses can include optical filters that attenuate light in one or more wavelength bands. The optical filters include the dye or dye mixtures used in chroma-enhanced lenses. The present disclosure provides chroma enhancing aminothiophene-isoxazolone dyes according to Formula I.

Abstract: Harmful light sources in the range from about 430 nm to about 470 nm are finding an increased use for marking, engraving, and cutting various materials. One such source of harmful light are lasers. Protection from laser hazards, including blue and violet wavelength laser sources, is an increasing need as applications for and use of both continuous wave and pulsed lasers continues to grow. Articles for laser protection and other harmful light sources can take many forms, such a shield, a lens, a window, a lid, a cover, a case, a plaque, a sheet, a film, clothing, a panel, a curtain, and articles in varying shapes that offer protection. Laser protection and protection from other harmful light sources (natural and artificial) can be achieved with protective articles that comprise at least one dye according to Formula I.
