1. A display system comprising:
an image projection device configured to emit a multiplexed light stream comprising a first light stream of a first color, a second light stream of a second color and a third light stream of a third color, said first, second, and third colors being different, said first, second, and third light streams comprising image content;
a waveguide comprising a material having a refractive index greater than 1.79, said waveguide configured to receive the multiplexed light stream emitted from the image projection device such that the first light stream, the second light stream and the third light stream are guided within the waveguide by multiple total internal reflections; and
at least one vari-focal optical element disposed to receive the multiplexed light stream output from the waveguide such that at least of portion of said multiplexed light stream is directed to a user's eye, said vari-focal optical element configured to vary the depth from which light from the waveguide appears to originate.
