I read it. Works on Mechanical movement to cause electrostatic charge. Not even close to EPGL. [0030] When the human eye blink or turn, the first polymer layer 12 and the second polymer layer 13 friction between the surface of electrostatic charge, electrostatic charge causes the generation of the first electrode 11 and the second electrode 14 changes the capacitance between, resulting in the first electrode 11 and second electrode 14 between the potential difference. The first electrode 11 and second electrode 14 respectively, through the wire to the power device 3, then to the power supply device 3. The power unit 3 may be provided in the center of the inner surface of contact lenses.
