Summary:An apparatus for use with a head wearable display includes a curved eyepiece for guiding display light to a viewing region offset from a peripheral location and emitting the display light along an eye-ward direction in the viewing region. The curved eyepiece includes a curved lightguide to guide the display light, an eye-ward facing surface that is concave, a world facing surface that is convex and opposite the eye-ward facing surface, and an optical combiner disposed at the viewing region to redirect the display light towards the eye-ward direction for output from the curved lightguide. The optical combiner is partially transmissive to ambient light incident through the world facing surface such that the viewing region is see-through. In some embodiments, a prism is disposed proximate to the input surface to pre-compensate the display light for lateral chromatic aberrations resulting the curved lightguide.
