The lens assembly may include a retention film on a rear surface of the glass layer with the front surface being free of a safety layer. The lens assembly may include a glass layer with a front surface to be engaged by a person and a rear surface and a retention film fixed to the rear surface and is transparent. A display generator may be fixed to the retention film. A spacing layer may be fixed on the retention film around the display generator. A mask may be fixed to a rear surface of the glass beneath the retention film. A support frame may engage the spacing layer and support the display generator with the glass layer being supported by the retention film and mechanically supported by both the display generator and the frame.
