Abstract
An ophthalmic device includes an enclosure, an electromyography sensor, and a controller. The enclosure is configured to mount in or on an eye. The enclosure further includes a first material and a second material disposed within the first material. The electromyography sensor is adapted to measure electrical activity of a muscle of the eye proximate to a first annular region of the ophthalmic device when the ophthalmic device is mounted in or on the eye. The electromyography sensor includes a first electrode and a second electrode, each positioned within the first annular region between the first material and at least a portion of the second material. The controller, coupled to the electromyography sensor, stores instructions that when executed causes the ophthalmic device to perform operations including acquiring a first signal representative of the electrical activity of the muscle by measuring the electrical activity with the electromyography sensor.
