Augmented and virtual reality display systems and methods for diagnosing health conditions based on visual fields
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:
an augmented reality display platform configured to pass light from the world into an eye of a wearer wearing the head-mounted system, wherein the display platform comprises:
a light source configured to project light into the eye of the wearer to form a moving image in the eye; and
a user interface configured to receive input from a user,
wherein the wearable augmented reality device is configured to project the image at a particular portion of a periphery of the wearer's visual field and to detect a response regarding the image to determine the health of that particular portion of the visual field,
wherein the device is configured to provide a visual, audio, or tactile alert based on detection of a hazardous condition in the wearer's surroundings, and
wherein the hazardous condition is invisible to the wearer due to a visual field deficiency.
2. The device of claim 1 , wherein the moving image moves inward from the periphery of the wearer's visual field toward the center of the wearer's visual field.
3. The device of claim 2 , wherein the wearable device is configured to detect a response from the wearer indicating a time at which the image becomes visible to the wearer.
4. The device of claim 2 , wherein the wearable device is configured to detect a response from the wearer regarding an observed characteristic of the image.
5. The device of claim 2 , wherein the light source is further configured to project an image of an object approaching the eye of the wearer.
6. The device of claim 1 , wherein the display platform comprises a fiber scanning display.
7. The device of claim 1 , wherein the device is configured to provide a visual, audio, or tactile notification to the wearer based on detecting a hazard in an unhealthy portion of the wearer's visual field.
8. A wearable augmented reality device comprising:
an augmented reality head-mounted ophthalmic system comprising:
an augmented reality display platform configured to pass light from the world into an eye of a wearer wearing the head-mounted system, wherein the display platform comprises:
a light source configured to project light into the eye of the wearer to form one or more moving images at multiple depth planes in the eye; and
a user interface configured to receive input from a user,
wherein the wearable augmented reality device is configured to project the image at a particular portion of a periphery of the wearer's visual field and to detect a response regarding the image to determine the health of that particular portion of the visual field,
wherein the display platform is configured to output light with different amounts of wavefront divergence corresponding to multiple depth planes to present virtual content on those depth planes, and
wherein the light source is further configured to project an image of an object approaching from one of the depth planes further from the eye of the wearer to one of the depth planes closer to the eye of the wearer.
