16. An eyewear control method for illuminating eyewear to be worn by a user, the method comprising:
detecting, by a controller in a support structure of the eyewear, a trigger signal instructing the controller to illuminate at least one light source comprising light emitting diode (LED) indicators supported by the support structure to indicate at least one of whether images are being recorded, whether video is being recorded, or whether sound is being recorded; and
in response to receiving the trigger signal, illuminating, by the controller, the at least one light source in the support structure such that the at least one light source emits light through a light diffuser on a surface of the support structure, the light diffuser positioned to diffuse light emitted by the at least one light source using microstructures and to redirect light emitted by the at least one light source at a specific emission angle towards an observer in proximity of the user in a comet-like pattern to convey to the observer that a camera is active,
wherein a select number of the LED indicators represent a length of a comet, a first LED indicator of the select number of LED indicators is brightest and represents a head of the comet, and remaining LED indicators of the select number of LED indicators get dimmer as they approach a final LED indicator of the select number of LED indicators.
