1. A display device comprising:
a waveguide assembly comprising a waveguide configured to output outcoupled light along an output surface of the waveguide; and
a first adaptive lens assembly having a first major surface facing the output surface, the first adaptive lens assembly comprising:
a first waveplate lens;
a second waveplate lens; and
a first switchable waveplate interposed between the first waveplate lens and the second waveplate lens, wherein the switchable waveplate is selectively switchable between:
a first state configured to pass the outcoupled light without altering a polarization state of the outcoupled light; and
a second state configured to alter the polarization state of the outcoupled light passing therethrough; and
a second adaptive lens assembly having a second major surface facing an external scene opposite the output surface, and a second minor surface facing the first major surface, the second adaptive lens assembly comprising:
a third waveplate lens;
a fourth waveplate lens; and
a second switchable waveplate interposed between the third waveplate lens and the fourth waveplate lens, wherein the second switchable waveplate is selectively switchable between:
a third state configured to pass light from the external scene without altering a polarization state of the light from the external scene; and
a fourth state configured to alter the polarization state of the light from the external scene passing therethrough.
