Eyelid Movement Sensor Device- Blinking Characterizing
Eyelid Movement Sensor Device- Blinking Characterizing
The investigators have developed a simple to use device that facilitates the monitoring of
 the upper eyelids motion, acquires the eyelid vertical movement and enables analysis and
 graphic presentation of the results. the device system consists 3 components : glasses for
 the patient including magneto sensitive probes, hardware and dedicated software.

 Our purpose is to characterize eyelid motion in normal population. The methods include
 measuring each patient 10 minutes during watching a short movie.
Essentially, for Hall-probes monitor the magnetic field generated by a tiny magnets attached
 to the upper eyelid.
