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.
