Augmented and virtual reality display systems and methods for diagnosing a user using electrical potentials
Configurations are disclosed for a health system to be used in various healthcare applications, e.g., for patient diagnostics, monitoring, and/or therapy. The health system may comprise a light generation module to transmit light or an image to a user, one or more sensors to detect a physiological parameter of the user's body, including their eyes, and processing circuitry to analyze an input received in response to the presented images to determine one or more health conditions or defects.
1. A wearable augmented reality device comprising:
an augmented reality head-mounted ophthalmic system comprising:

in-coupling diffractive optical elements configured to in-couple light from the light source; and
out-coupling diffractive optical elements configured to out-couple light to the eye of the wearer,
wherein one or more waveguides of the plurality of waveguides are configured to output light with a different amount of wavefront divergence than one or more other waveguides of the plurality of waveguides, wherein the different amounts of wavefront divergence correspond to different focal planes;
a plurality of electrodes attached to the frame and configured to be placed around the eye, wherein the electrodes are configured to measure electrical potentials of a retina of the eye.
