Fluid filled adjustable contact lenses

1. A fluid-filled adjustable contact lens comprising:

a front surface and a back surface;

a lens chamber disposed between the front surface and the back surface,

wherein the lens chamber comprises a front membrane sealed to a back membrane;

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

wherein the front surface and the back surface are configured to counteract astigmatism caused by deformation of the lens chamber;

wherein the fluid-filled adjustable contact lens is located outside of an eyeball of the user;

a reservoir fluidly connected to the lens chamber;

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

wherein the fluid-filled adjustable contact lens is configured so that the transfer of the fluid causes a change in an optical power of the fluid-filled adjustable contact lens by changing a first curvature of the front membrane of the lens chamber, which causes a change of a second curvature of the front surface of the fluid-filled adjustable contact lens;

wherein the reservoir and the actuator are housed within the fluid-filled adjustable contact lens;

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.
