Abstract: Embodiments are described of a light guide including a proximal end, a distal end, a front surface and a back surface, an ambient input region on the front surface near the distal end, and an output region on the back surface near the distal end. A beamsplitter having a plurality of faces has one face optically coupled to the proximal end of the light guide, and a display is optically coupled to another face of the beamsplitter. A projector assembly is optically coupled to a face of the beamsplitter opposite the beamsplitter face that is optically coupled to the light guide. A reflecting element having optical power is positioned at the distal end of the light guide, and a distal optical element is positioned in the light guide near the distal end.
