Abstract
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.
Claims19
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, and
- wherein different waveguides of the plurality of waveguides output the light of the optics with different amounts of wavefront divergence corresponding to different depth planes.
A wearable virtual reality device comprising:
- a virtual reality head-mounted ophthalmic system comprising a wearable virtual reality display platform comprising optics configured to output light to form an image in an eye of a wearer, wherein the virtual reality display platform comprises a fiber scanning display,
- wherein the virtual reality head-mounted ophthalmic system is configured to conduct an eye exam by automatically varying a focus of the image to provide incremental change in optical prescription,
- wherein the optics comprise a waveguide stack comprising a plurality of waveguides,
- wherein each waveguide of the plurality of waveguides comprises out-coupling diffractive optical elements configured to out-couple the light, propagating through each waveguide by total internal reflection, into the eye of the wearer with wavefront divergence corresponding to a depth plane, and
- wherein different waveguides of the plurality of waveguides output the light with different amounts of wavefront divergence corresponding to different depth planes.
