Abstract: A contact lens, intended to be worn on the eye of a person, for automatically aiming in the direction of the eye. The contact lens includes:—a membrane suitable for covering the pupil and the iris of the eye;—at least two light sources encapsulated in the membrane, each suitable for emitting a light beam whose divergence is controlled in relation to the axis of the lens;—at least one interface for collecting and supplying electrical energy to the light sources, from outside the lens;—at least one electronic circuit suitable for activating the sources from the interface.

Abstract: An optical system for detecting and tracking the eye movements of an individual. The system includes a frame, intended to be worn on the face of the individual, that includes a plurality of illumination sources. The system includes at least one contact lens, intended to be worn by an eye of the individual facing the frame, in which are encapsulated: an autonomous integrated circuit, a plurality of photoreceptors and a wireless communication transmitter. Variation in a signal (e.g., voltage or current) delivered by the photoreceptors allows not only the closure of the eyelid but also eye movements to be detected.
