US 2019/0171037 A1 · LENS-TO-LENS COMMUNICATION FOR CONTACT LENSES

Abstract

A contact lens includes a sensing electrode, detection circuitry, and a lens. The sensing electrode senses an impedance that changes based upon overlap of an eyelid. The detection circuitry is coupled to the sensing electrode and configured to measure the impedance via the sensing electrode. The detection circuitry is configured to generate a control signal indicative of a gaze direction of the eye based upon the electrical impedance. The lens is integrated into the contact lens and has an optical power that is adjustable. The lens is coupled to adjust the optical power in response to the control signal output from the detection circuitry and which is indicative of the gaze direction.

Dependent claims

A contact lens for mounting on an eye, the contact lens including:

one or more sensing electrodes for sensing an impedance that changes based upon overlap of an eyelid of the eye when the contact lens is mounted on an eye;
detection circuitry coupled to the one or more sensing electrodes and configured to measure the impedance via the one or more sensing electrodes, wherein the detection circuitry is configured to generate a control signal indicative of a gaze direction of the eye based upon the impedance;
and
a lens integrated into the contact lens and having an optical power that is adjustable, the lens coupled to adjust the optical power in response to the control signal output from the detection circuitry and which is indicative of the gaze direction.
