An electronic imaging assembly is supported by the housing assembly outside of the user's field of view and in communication with circuitry within the housing assembly to produce an image. An optical element is provided comprising a transparent fixture supporting an eyepiece assembly in front of a user's eye. The transparent fixture is located to receive the image from the electronic imaging assembly and relays the image to the eyepiece assembly, which directs the image to the user's eye. The display device is a light weight, compact, ergonomic, remountable display system that combines an image relay system and mechanical support with a simple mounting system that can be applied to eyeglasses or other head gear.
