Abstract

The present invention discloses an ophthalmic device with micro-acoustic electromechanical elements and associated methods. In some embodiments, the micro-acoustic electromechanical elements may be useful for the purpose of providing audible warnings and/or messages to a user. The audible warnings and/or messages can include, for example, messages transmitted wirelessly through a communication element of the ophthalmic device and/or generated within the ophthalmic device. In addition, in some embodiments the ophthalmic device can be an energized contact lens that is used both for optical correction and the transmission of sound through bone resonance to the inner ear of a user.
