Abstract: An optical element includes a transparent layer, outcoupling elements, and a waveguide structure. The outcoupling elements are positioned across the transparent layer. The waveguide structure provides non-visible light to the outcoupling elements and the outcoupling elements outcouple the non-visible light as non-visible illumination light to illuminate an eye region.

Abstract: Outcoupling elements are disposed with a transparent layer. A transparent waveguide structure receives non-visible light and delivers the non-visible light to the outcoupling elements. The outcoupling elements outcouple the non-visible light as non-visible illumination light.
