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.
