1. A display system comprising:

  • a head-mountable display configured to project light to a viewer to display image information on one or more depth planes, the display comprising;

    one or more waveguides configured to project the light to the viewer, wherein the one or more waveguides are further configured to transmit light from objects in a surrounding environment to the viewer;

    a first variable focus lens element between the one or more waveguides and a first eye of the viewer, wherein the first variable focus lens element is configured to modify the projected light to correct for a refractive error of the first eye of the viewer; and

    a second variable focus lens element between the one or more waveguides and the surrounding environment, wherein the second variable focus lens element is configured to modify light from objects in the surrounding environment to correct for a refractive error of the first eye of the viewer.
