1. A method of operating a dynamic eyepiece in an augmented reality headset, the method comprising:
producing first virtual content associated with a first depth plane;
coupling the first virtual content into the dynamic eyepiece;
projecting the first virtual content through one or more waveguide layers of the dynamic eyepiece to an eye of a viewer, wherein the one or more waveguide layers are characterized by a first surface profile;
coupling a mechanical structure to the one or more waveguide layers, wherein the mechanical structure contacts a periphery of the one or more waveguide layers;
applying, using the mechanical structure, a mechanical force to the periphery of the one or more waveguide layers to modify the one or more waveguide layers to be characterized by a second surface profile different from the first surface profile;
producing second virtual content associated with a second depth plane;
coupling the second virtual content into the dynamic eyepiece; and
projecting the second virtual content through the one or more waveguide layers of the dynamic eyepiece to the eye of the viewer.
