ELECTRONIC OPHTHALMIC LENS WITH SLEEP MONITORING

摘要

An eyelid position sensor system and/or an eye movement sensor system for an ophthalmic lens having an electronic system is described herein for recording data associated with sleep 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 system controller and a data manager. In at least one embodiment, the eyelid position sensor system is utilized to determine eyelid position and the eye movement sensor system is utilized to determine eye position for the system controller to determine if the wearer is awake, asleep, or in REM sleep.

1. A method for monitoring sleep with a powered ophthalmic lens, the method comprising:
activating the powered ophthalmic lens; initiating an accumulator on the lens to track a passage of time; determining at a first lid sampling rate whether lid closure has occurred; when lid closure is detected,
sampling at least once at least one of an accelerometer and a transducer, anddetermining whether a threshold is exceeded, when the threshold is exceeded
retrieving a reading from the accumulator;storing the accumulator reading and a reading of the at least one of the accelerometer and the transducer; anddetermining whether the reading is below the threshold, when the reading is below the threshold, storing an indication of a REM end and returning to sampling lid closure.
