Abstract

In one example an automatic false pupil contact lens comprises a body formed from an optically translucent material and a coating on the body formed from at least one of a photochromatic material or an electrochromatic material that, in response to an input, is to change between a first state in which the coating is optically translucent and a second state in which the coating is optically opaque in response to an input. Other examples may be described.

First claim

What is claimed is:

1 . An automatic false pupil contact lens, comprising:
a body formed from an optically translucent material; and a coating on the body formed from at least one of a photochromatic material or an electrochromatic material that, in response to an input, is to change between a first state in which the coating is optically translucent and a second state in which the coating is optically opaque.

2 . The automatic false pupil contact lens of claim 1 , wherein the body is formed from at least one of a polymer material or a glass material.

3 . The automatic false pupil contact lens of claim 1 , wherein:
the coating comprises a photochromatic material arranged in a plurality of concentric rings; and the coating comprises a photosensitivity which varies between the respective concentric rings.

4 . The automatic false pupil contact lens of claim 3 , wherein the photosensitivity increases in successively larger concentric rings.

5 . The automatic false pupil contact lens of claim 1 , wherein the coating comprises a photosensitivity which increases as a function of distance from a central point on the body.

6 . The automatic false pupil contact lens of claim 1 , wherein:
the coating comprises an electrochromatic material arranged in a plurality of concentric rings.

7 . The automatic false pupil contact lens of claim 6 , further comprising circuitry to:
selectively apply an electrical impulse to one or more of the concentric rings in response to a signal.

8 . The automatic false pupil contact lens of claim 7 , wherein:
the coating comprises an electrosensitivity which varies between the respective concentric rings; and the electrical impulse applied to the concentric rings varies as a function of the electrosensitivity of the coating in the respective concentric rings.

9 . The automatic false pupil contact lens of claim 7 , wherein:
the coating comprises an electrosensitivity which is consistent between the respective concentric rings; and the electrical impulse applied to the concentric rings is consistent across the respective concentric rings.

10 . The automatic false pupil contact lens of claim 6 , wherein the coating comprises a photosensitivity which increases as a function of distance from a central point on the body.

11 . An electronic device, comprising:
at least one light sensor to detect an ambient light condition; and a controller comprising logic, at least partially including hardware logic, to:
receive an input from the at least one light sensor, wherein the input reflects the ambient light condition;
determine an appropriate pupil size for the ambient light condition; and
in response to a determination that a difference between the appropriate pupil size and a current pupil size is not within a threshold, to generate a pupil size signal to be transmitted to an automatic false pupil contact lens.

12 . The electronic device of claim 11 , wherein the controller further comprises logic, at least partially including hardware logic, to:
form a time series data of ambient light condition data collected by the at least one light sensor.

13 . The electronic device of claim 12 , wherein the controller further comprises logic, at least partially including hardware logic, to:
apply a smoothing factor to the time series data of ambient light conditions.

14 . The electronic device of claim 11 , wherein the logic to determine an appropriate pupil size for the ambient light condition further comprises logic, at least partially including hardware logic, to implement a training process to:
receive a first output from the at least one light sensor, wherein the input reflects the ambient light condition; receive a second input from a user of the electronic device, wherein the second input comprises an instruction to adjust a pupil size of the automatic false pupil contact lens; and receive a third input from a user of the electronic device, wherein the third input comprises an indication that the pupil size of the automatic false pupil contact lens is appropriate for the user.

15 . The electronic device of claim 14 , wherein the logic to determine an appropriate pupil size for the ambient light condition further comprises logic, at least partially including hardware logic, to implement a training process to:
determine the pupil size of the automatic false pupil contact lens that is appropriate for the user; and record in a machine readable memory the output of the at least one light sensor in logical association with the pupil size of the automatic false pupil contact lens that is appropriate for the user.

16 . The electronic device of claim 11 , wherein the electronic device further comprises:
a sensor to determine a current pupil size on the automatic false pupil contact lens.

17 . The electronic device of claim 11 , wherein the controller further comprises:
a receiver to receive a current pupil size on the automatic false pupil contact lens.

18 . The electronic device of claim 11 , further comprising:
a transmitter to transmit the pupil size signal to the automatic false pupil contact lens.

19 . The electronic device of claim 18 , wherein:
in response to receiving the pupil size signal, the automatic false pupil contact lens applies an electrical impulse to an electrochromatic coating on a portion of the automatic false pupil contact lens.

20 . The electronic device of claim 19 , wherein the electrical impulse causes a change in a dimension of a pupil portion of the automatic false pupil contact lens.
