An eyelid position sensor system for an ophthalmic lens comprising an electronic system is described herein for determining at least one of drowsiness or sleep onset of the wearer. The eyelid position sensor system is part of an electronic system incorporated into the ophthalmic lens. The electronic system in at least one embodiment includes a power source, power management circuitry, one or more sensors, clock generation circuitry, control algorithms and circuitry, and an alert mechanism. The eyelid position sensor system is utilized to determine eyelid position and use this information to determine if the wearer is asleep or awake. 2756816v1 1401 1418 1414 1408 Power Alert Source Mechanism Sensor Amlfe L e nA m lif er 14 06 - - A na log -to - D ig ita l S yste m digital - Signal C nrle 1 ~converter Processor Cnrle Sensor Amplifier 1410 1416 1412 Sensor Amplifier
