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.

First claim

1 . (canceled)

2 . A wearable augmented reality 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, the display configured to:
pass light from the world into an eye of; and
output light from the light source into the eye of the wearer to form an image in the eye,

wherein the wearable augmented reality device is configured to:
detect an amount of one or more wavelengths of light propagating towards the eye; and
modify the amount of the one or wavelengths of light reaching the eye based on the detected amount.

3 . The device of claim 2 , wherein the head-mounted ophthalmic system is configured to modify the amount of the one or wavelengths of light based on one or more of a time of day, a date, a time of year, or a season.

4 . The device of claim 3 , wherein the head-mounted ophthalmic system is configured to modify an amount of blue light reaching the eye depending on temporal proximity to a sleep time of the wearer.

5 . The device of claim 3 , wherein the one or wavelengths of light comprise wavelengths of light corresponding to the color blue.

6 . The device of claim 2 , wherein the head-mounted ophthalmic system is configured to:
block at least a portion of the wearer's view of the world, thereby reducing the amount of the one or more wavelengths of light reaching the eye from the world, wherein a size and location of the portion of the wearer's view of the world that is blocked is determined based on the detected amount of the one or more wavelengths of the light.

7 . The device of claim 2 , wherein the head-mounted ophthalmic system is configured to actively reduce the amount of light of the one or more wavelengths by reducing the amount of light of the one or more wavelengths emitted by the light source.

8 . The device of claim 7 , wherein the head-mounted ophthalmic system is configured to:
provide instructions for the amount of light of the one or more wavelengths to be outputted by the light source; and subsequently modify the instructions to reduce an output of the light of the one or more wavelengths by the light source.

9 . The device of claim 2 , further comprising one or more light sensors attached to the frame and configured to detect an amount of the one or more wavelengths of light incident on the head-mounted system.

10 . The device of claim 9 , wherein the one or more sensors is a camera.

11 . The device of claim 9 , wherein the one or more sensors is configured to detect an overexposure of light of a particular color based on the light exceeding a threshold for the particular color, wherein the head-mounted system is configured to reduce an amount of the light of the particular color reaching the eye.

12 . The device of claim 2 , wherein the display comprises a waveguide stack comprising a plurality of waveguides, wherein different waveguides of the waveguide stack are configured to output light with different wavefront divergence corresponding to different focal planes.

13 . A wearable augmented reality 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, the display configured to:
pass light from the world into an eye of; and
output light from the light source into the eye of the wearer to form an image in the eye,

wherein the wearable augmented reality device is configured to selectively administer light of a portion of a light spectrum into the wearer's eyes.

14 . The device of claim 13 , wherein the wearable augmented reality device is configured to selectively administer light based on one or more of a time of day, a date, a time of year, or a season.

15 . The device of claim 13 , further comprising one or more sensors configured to detect an under exposure, relative to a threshold, of light of the portion of the light spectrum, wherein the wearable augmented reality device is configured to selectively augment the light based on the detected under exposure.

16 . The device of claim 15 , further comprising one or more sensors attached to the frame and configured to detect an underexposure of blue light, wherein the wearable augmented reality device is configured to selectively administer blue light.

17 . The device of claim 13 , wherein the light comprises a range of wavelengths corresponding to daylight.

18 . The device of claim 13 , wherein the light comprises a range of wavelengths corresponding to full spectrum light.

19 . The device of claim 13 , further comprising a second light source configured to provide the light to be selectively administered to the wearer's eyes.

20 . A wearable augmented reality 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, the display configured to:
pass light from the world into an eye of; and
output light from the light source into the eye of the wearer to form an image in the eye,

wherein the wearable augmented reality device is configured to selectively administer light of a predefined range of wavelengths into the wearer's eyes based on a treatment protocol.

21 . The device of claim 20 , wherein the treatment protocol comprises administering a prescribed amount of the light of the predefined range of wavelengths periodically.

22 . The device of claim 20 , wherein the treatment protocol comprises administering a prescribed amount of the light of the predefined range of wavelengths continuously.

23 . The device of claim 20 , wherein the wearable augmented reality device is configured to modify the predefined range of wavelengths based on a time of day.

24 . The device of claim 20 , wherein the wearable augmented reality device is configured to modify the predefined range of wavelengths based on a calendar date.

25 . The device of claim 20 , wherein the wearable augmented reality device is configured to modify the predefined range of wavelengths based on one or more of a current season and a location of the wearer.

26 . The device of claim 20 , wherein the wearable augmented reality device is configured to determine a treatment protocol for selectively administering the light of the certain portion of the spectrum into the wearer's eyes.

27 . The device of claim 26 , wherein the wearable augmented reality device is configured to determine the treatment protocol based on one or more of the following: a physiological state of the wearer, a mood of the wearer, and an ambient environment around the wearer.

28 . The device of claim 26 , wherein the wearable augmented reality device is configured to determine the treatment protocol based on a sign of depression or other abnormality of the wearer.

29 . The device of claim 26 , wherein the wearable augmented reality device is configured to determine the treatment protocol based on input from the wearer.
