1. An augmented reality device comprising:

  • an augmented reality head-mounted ophthalmic system comprising a wearable augmented reality display platform configured to pass light from the world into an eye of a wearer wearing the head-mounted ophthalmic system, the augmented reality display platform comprising optics configured to output light to form an image in the eye,wherein the augmented reality head-mounted ophthalmic system is configured to conduct an eye exam by automatically varying a focus of the image to provide incremental changes in optical prescription,wherein the optics comprise a waveguide stack comprising a plurality of waveguides, andwherein different waveguides of the plurality of waveguides output the light of the optics with different amounts of wavefront divergence corresponding to different depth planes.
