1. An electronic device comprising:
an augmented reality (AR) display device comprising:
eyeglasses having one or more lenses configured to be positioned in front of eyes of a person;
at least one first camera sensor that detects ambient light;
an AR projector that displays AR imagery on the one or more lenses; and
at least one second camera sensor configured to detect whether the eyes of the person are open or closed; and
a controller communicatively coupled to the AR display device, and which:
detects brightness of the ambient light;
dynamically adjusts brightness of the AR imagery in relation to the brightness of the ambient light; and
reduces the brightness of the AR imagery in response to determining a brightness context that the eyes of the person have been closed for longer than a threshold period of time.
