Abstract
In some aspects, an electronic contact lens for treating dry eye is presented. According to some aspects, the electronic contact lens includes a concave surface configured to conform to an eye of a patient, a sensor configured to generate a signal indicative of an eyelid movement, and at least one capacitor configured to store energy used for stimulating the eye. The electronic contact lens may further include at least two electrodes coupled to the at least one capacitor, wherein the at least two electrodes are exposed to the concave surface and configured to deliver power from the at least one capacitor to stimulate the eye. The electronic contact lens further includes a processor coupled to the sensor and electrodes. The processor may be configured to compute a blink rate from the sensor output, and, based on the blink rate, activate the at least two electrodes to stimulate the eye.
