Abstract

A fluid-filled adjustable contact lens is provided. An exemplary contact lens includes a lens chamber configured to be positioned on a pupil of a user wearing the contact lens; a reservoir fluidly connected to the lens chamber; an actuator configured to transfer fluid back and forth between the lens chamber and the reservoir; a sensor configured to sense movement from the user and transmit a control signal when a predetermined movement is performed by the user; and a processor configured to actuate the actuator upon receipt of the control signal from the sensor.

Claims

1. A fluid-filled adjustable contact lens comprising:

a lens chamber configured to be positioned on a pupil of a user wearing the contact lens;

a reservoir fluidly connected to the lens chamber;

an actuator configured to transfer fluid back and forth between the lens chamber and the reservoir;

a sensor configured to sense movement from the user and transmit a control signal when a predetermined movement is performed by the user; and

a processor configured to actuate the actuator upon receipt of the control signal from the sensor.

2. The contact lens of claim 1, wherein the sensor is a pressure sensor configured to detect blinking by the user wearing the contact lens, and wherein the predetermined movement is a predetermined blinking pattern.

3. The contact lens of claim 1, wherein the sensor is a microaccelerometer configured to detect motion of the user'"'"'s eyeball, and wherein the predetermined movement is a predetermined pattern of movement of the user'"'"'s eyeball.

4. The contact lens of claim 1, wherein the sensor is a sensor configured to detect movement of the user'"'"'s eyebrows, and wherein the predetermined movement is a predetermined pattern of movement of the user'"'"'s eyebrows.

5. The contact lens of claim 1, further comprising a capacitive power source configured to supply power to the actuator and the processor.

6. The contact lens of claim 5, further comprising:

a thermoelectric power generator configured to supply power to the capacitive power source by harnessing power from a temperature gradient over the contact lens.

7. The contact lens of claim 5, further comprising:

a piezoelectric component configured to convert a blinking pressure force into electricity for storage in the capacitive power source.

8. The contact lens of claim 5, wherein the capacitive power source is an inductive power source.
