1. A dynamic eyepiece for projecting an image to an eye of a viewer, the dynamic eyepiece comprising:
a waveguide layer having an input surface, an output surface opposing the input surface, and a periphery, wherein the waveguide layer is configured to propagate light therein; and
a mechanical structure has a first portion in contact with a first portion of the periphery of the waveguide layer and a second portion in contact with a second portion of the periphery of the waveguide layer, wherein the mechanical structure is operable to:
apply a first mechanical force to the first portion or the second portion of the periphery of the waveguide layer to impose a first surface profile on the output surface of the waveguide layer; and
apply a second mechanical force to the first portion or the second portion of the periphery of the waveguide layer to impose a second surface profile different from the first surface profile on the output surface of the waveguide layer.
