1. An augmented reality device comprising:
a display;
a controller;
an ambient light sensor, operably coupled to the controller, to sense an ambient light level; and
a variable transmissive-reflective (transflective) device, operably coupled to the controller and in optical communication with the display, to direct light from the display and ambient light to a user's eye in a proportion determined by the controller based on the ambient light level without totally internally reflecting the light from the display, wherein the variable transflective device comprises:
a transmissive section to reflect some of the light from the display and to transmit some of the ambient light to the user's eye in the proportion determined by the controller based on the ambient light level; and
a reflective section, next to the transmissive section, to reflect some of the light from the display to the user's eye and to block some of the ambient light.
