Abstract
An embodiment includes eyewear comprising an optical element, a controller, a support structure configured to support the optical element and the controller, light sources coupled to the controller and supported by the support structure, and a diffuser positioned adjacent to the light sources and supported by the support structure, the diffuser including microstructures that diffuse light emitted by the light sources in a radial anisotropic diffusion pattern or a prism-like diffusion pattern.
Claims17
Eyewear comprising:
- an optical element;
- a controller;
- a support structure configured to support the optical element and the controller, wherein the support structure comprises a frame holding lenses of the eyewear;
- light sources coupled to the controller and supported by the support structure;
- and
- a diffuser positioned adjacent to the light sources and supported by the support structure, the diffuser including microstructures that diffuse light emitted by the light sources in a radial anisotropic diffusion pattern;
- wherein the diffuser has a circular shape and the radial anisotropic diffusion pattern diffuses the light in a radial direction around the circular shape;
- and
- wherein the light sources are positioned in a circular pattern on the frame and the diffuser is positioned in front of the light sources on the frame such that the diffuser diffuses the light of each of the light sources differently according to their respective position in the circular pattern.

An eyewear control method for illuminating eyewear, the method comprising:
- detecting, by a controller in a support structure of the eyewear, a trigger signal instructing the controller to illuminate light sources in the support structure, wherein the support structure comprises a frame holding lenses of the eyewear;
- and
- in response to receiving the trigger signal, illuminating, by the controller, the light sources in the support structure such that the light sources emit light through microstructures of a diffuser in the eyewear in a radial anisotropic diffusion pattern
- wherein the diffuser has a circular shape and the radial anisotropic diffusion pattern diffuses the light in a radial direction around the circular shape;
- and
- wherein the light sources are positioned in a circular pattern on the frame and the diffuser is positioned in front of the light sources on the frame such that the diffuser diffuses the light of each of the light sources differently according to their respective position in the circular pattern.
