ELECTRONIC OPHTHALMIC LENS WITH EMITTER-DETECTOR PAIR SENSOR

摘要

An emitter-detector pair sensor may be incorporated into a powered or electronic ophthalmic lens. The emitter-detector pair sensor may be configured to determine the 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.

主权项

1. A powered ophthalmic lens, the powered ophthalmic lens comprising:
a contact lens including an optic zone and a peripheral zone; and an emitter-detector pair sensor system incorporated into the peripheral zone of the contact lens, the emitter-detector pair sensor system comprising an emitter for sending out a signal, a detector for capturing a reflection of the signal, a controller operatively associated with the emitter and detector configured to determine the distance between the contact lens and an object and output a control signal based on the determined distance, and at least one actuator configured to receive the control signal and implement a predetermined function.
