1. A wearable augmented reality device configured to be used by a wearer, the device comprising:

  • an augmented reality head-mounted ophthalmic system comprising;

    a frame configured to be worn on the head of a wearer wearing the head-mounted ophthalmic system;

    an augmented reality display attached to the frame and comprising;

    a light source, anda waveguide stack comprising a plurality of waveguides,wherein each waveguide is configured to propagate light therein by total internal reflection between opposing surfaces of the waveguide and wherein each waveguide comprises out-coupling diffractive optical elements configured to out-couple light into an eye of the wearer with wavefront divergence corresponding to a depth plane,wherein one or more waveguides of the plurality of waveguides are configured to output light to an eye of the wearer with a different amount of wavefront divergence than one or more other waveguides of the plurality of waveguides, and wherein different amounts of wavefront divergence provide different accommodation by the eye and are associated with different depth planes away from the wearer,wherein the augmented reality display is configured to pass light from the world into an eye of the wearer and output, via the waveguide stack, light into the eye of the wearer to form an image in the eye,wherein the augmented reality head-mounted ophthalmic system is configured to deliver a therapy to the wearer, wherein the therapy is selected from the group consisting of tactile therapy, sound therapy, and temperature therapy.
