1. A waveguide comprising:
an optically transparent layer comprising optically transparent material and a plurality of surfaces that are arranged to guide light in the waveguide by total internal reflection, wherein the light includes image information; and
an in-coupling optical element that is configured to deflect the light into the waveguide such that the light is guided in the optically transparent layer, wherein the in-coupling optical element includes:
a prism, and
a lens that is integrated with the prism and that comprises curvature to provide optical power to the light that is incident on the in-coupling element and deflected thereby into the waveguide.
