1. A method comprising:
focusing, via an adaptive lens assembly of a head mounted augmented reality display device, virtual images at a plurality of depth planes among a real world view,
wherein the adaptive lens assembly comprises a lens stack supported by the head mounted augmented reality display device and is configured to exert polarization-dependent optical power to linearly polarized light,
wherein the lens stack comprises a birefringent lens and an isotropic lens contacting each other to form a conformal interface therebetween, and
wherein the focusing includes selectively switching the adaptive lens assembly between a plurality of states having different optical powers to focus the virtual images at the plurality of plane depths among the real world view while simultaneously refocusing the real world view to appear without substantial distortion.
