PROBLEM TO BE SOLVED: To provide a powered or electronic ophthalmic lens in which an emitter-detector pair sensor is incorporated.;SOLUTION: An emitter-detector pair sensor may be configured to determine a distance from the sensor to an object in its path. Based upon this information, a system controller of the ophthalmic lens may output a signal to an actuator of the ophthalmic lens to control a variable power optic of the ophthalmic lens.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
