Electronic ophthalmic lens with sleep monitoring

This invention describes a powered contact lens designed to monitor a wearer's sleep. It uses tiny sensors embedded in the lens to detect eyelid position by measuring at multiple vertical points. This data, along with eye movement information, is processed by a small computer system within the lens to determine if the wearer is awake, asleep, or in REM sleep, storing the readings for later analysis.

Why it matters: The fundamental challenges of integrating a reliable power source and complex, miniaturized, biocompatible electronics into a contact lens for continuous wear remain significant. While flexible electronics have advanced, a breakthrough enabling this specific combination of components within the form factor of a contact lens for sleep monitoring has not yet materialized.
