Abstract
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.
Claims8
A powered ophthalmic lens, the powered ophthalmic lens comprising:
- a contact lens;
- an eyelid position sensor system in the contact lens, the eyelid position sensor system including a sensor array having a plurality of measurement points vertically spaced from each other to detect eyelid position and a signal conditioner configured to sample the measurement points in the sensor array to detect eyelid position and provide an output lid signal;
- an eye movement sensor system in the contact lens, the eye movement sensor system including at least one sensor to track and determine eye position and a signal conditioner cooperatively associated with the sensor and configured to track and determine eye position in spatial coordinates based on information from the sensor output and provide an output movement signal;
- a system controller electrically connected with said eyelid position sensor system and said eye movement sensor system, said system controller configured to sample said eyelid position sensor system and said eye movement system based on at least one predetermined sampling rate;
- and
- a memory in electrical communication with said system controller, and
- wherein said system controller stores data based on each sample in said memory.
