A tinted optical article includes an optical substrate providing with an optical filter wherein the optical filter is configured to selectively emit light in at least one selected range of wavelengths of light in the visible spectrum of 460 nm to 530 nm, allowing retinal exposure of a wearer eye to chronobiological blue-enriched light.
Claims19
A tinted optical article comprising an optical substrate with an optical filter, wherein:
- the optical article has a front and rear face, the rear face configured to be located proximate to a wearer eye,
- the optical filter is configured to selectively emit light in at least one selected range of wavelengths of light in the visible spectrum of 460 nm to 530 nm, allowing retinal exposure of a wearer eye located proximate to the rear face of the optical article to said at least one selected range of wavelengths of light without impairing the tint of the optical article, and
- the optical filter is configured to selectively and substantially reflect the selected range of wavelength of light that impinges the rear face of the optical article in the direction of said wearer eye such that the optical filter emits the selected range of wavelength of light to said wearer eye.
