Claim:
1. A system for providing an alarm cue to a wearer of an ophthalmic lens on an eye, the system comprising: a timing circuit configured to track a passage of time; a communications system configured for facilitating at least one-way communication for receiving data; an alert mechanism configured to provide an alert, wherein the alert mechanism comprises at least one of the following: a light source positioned on the lens to provide a light onto at least one of a retina of a wearer of said lens and said lens itself as the alert, a transducer to vibrate the eye of the wearer of said lens as the alert, an electrical simulator configured to stimulate at least one of a corneal surface, a scleral surface, a sensory nerve of a cornea, and a sensory nerve of a sclera, and a transducer that provides optic zone modification of an optic zone of said lens; a system controller electrically connected to said timing circuit, said communication system, and said alert mechanism, said system controller configured for controlling said timing circuit, said communication system, and said alert mechanism; and an eyelid position sensor system incorporated into said lens, the eyelid position sensor system having a plurality of vertical points to detect eyelid position, wherein said system controller is in electrical communication with said eyelid position sensor system to receive a signal from said eyelid position sensor system representative of eyelid position, said system controller triggering an escalation of alerts from said alert mechanism when the eyelid remains closed and the accumulator value exceeds an alarm value, said ophthalmic lens capable of encapsulating at least a portion of said timing circuit, said communications system, said alert mechanism and said system controller.
