Abstract
Some implementations of augmented reality glasses disclosed herein include an eyeglass substrate, two or more display elements, image optics configured for coupling light from the display elements into the eyeglass substrate and beam-splitting optics configured for directing light from the eyeglass substrate towards a viewer's eye and for allowing partial light from the real-world scene to arrive at a viewer's eye. The image optics may include one or more image optics lenses formed in the eyeglass substrate and may be positioned out of a line of sight of the viewer's eye when the viewer is wearing the augmented reality glasses. The image optics may be capable of coupling light from the display elements toward the beam-splitting optics along folded light paths caused by internal reflection within the eyeglass substrate.
