  • Publication number: 20230391028
    Abstract: The present disclosure includes optical articles comprising a lens having first and second lens surfaces and a protective layer having first and second protective surfaces that is coupled to the lens such that the first protective surface is disposed on the second lens surface. The optical article can comprise a plurality of convex or concave optical elements defined on the second lens surface or the first protective surface. The protective layer can have a maximum thickness larger than a maximum height of each of the optical elements such that the protective layer encapsulates the optical elements.

  • Publication number: 20140300857
    Abstract: An optical device including: an optical substrate provided with selective optical filtering element configured to selectively inhibit transmission, through the optical substrate of at least one selected range of wavelengths of incident light in the visible light spectrum at an inhibition rate of at least 5%, the selective optical filtering element being further configured to transmit at least 8% of incident light of the visible spectrum outside the at least one selected range of wavelengths; wherein the at least one selected range of wavelengths has a bandwidth in a range of from 10 nm to 70 nm, preferably 10 nm to 60 nm centered on a wavelength within a range of between 430 nm and 465 nm.
