1. An augmented reality device, comprising:
a first tunable lens characterized by a first lens curvature and a first lens depth;
a second tunable lens characterized by a second lens curvature and a second lens depth;
a waveguide positioned between the first tunable lens and the second tunable lens, the waveguide being configured to direct light representing virtual content through the first tunable lens and towards a user of the augmented reality device;
a light source configured to emit the light representing the virtual content into the waveguide; and
a processor configured to:
cause the light source to emit the light in accordance with a scan pattern that results in the light being emitted through different peripheral regions of the first tunable lens; and
direct the first tunable lens to shift at least a portion of the light received from the light source at one or more peripheral regions of the first tunable lens towards a central region between the different peripheral regions.
