Abstract: Adaptive spectacles (20) include a frame (23), including a front piece (24) and temples (26) connected to respective edges of the front piece. Right and left electrically tunable lenses (30) are mounted in the front piece. Communication circuitry (68) disposed in the frame is configured to communicate over a wireless link with a mobile computing device (32) in proximity to the adaptive spectacles. Control circuitry (64) disposed in the frame is configured to apply control voltage waveforms to the electrically tunable lenses in order to set a refractive property of the electrically tunable lenses and to modify the control voltage waveforms in response to a command received over the wireless link by the communication circuitry from the mobile computing device.
