Abstract
A powered ophthalmic lens having an electronic system is described herein configured to communicate with an external device using an ultrasound module for creating a sound pressure wave(s) to be transmitted through a medium, e.g. air, to an external device. The ophthalmic lens includes at least one ultrasound module having at least one transducer such as a pair of transmit and receive transducers, a transceiver transducer or a plurality of transducers. The ultrasound module includes additional components for the creation and reception of the sound pressure wave(s). In an alternative embodiment, there is one ultrasound module with a multiplexer connected to a plurality of transducers. In at least one embodiment, the sound pressure wave(s) encodes a message from the external device to the contact lens. In at least one alternative embodiment, the sound pressure wave(s) encodes a message from the contact lens to the external device.
