Methods and systems for diagnosing and treating higher order refractive aberrations of an eye

A wearable augmented reality device, the device comprising:

• at least one light source;
• and wearable optics configured to:
• pass light from the world into an eye of a person wearing the head-mounted system;
• and
• output light from the at least one light source for propagation into the eye of the person to form an image in the eye, the at least one light source and wearable optics configured to provide refractive correction for higher order refractive errors;
• wherein the wearable optics comprise a waveguide stack comprising a plurality of waveguides, wherein the waveguide stack is configured to output the light from the at least one light source for propagation into the eye with wavefront divergence corresponding to different depth planes.
