Abstract
Adaptive spectacles include a spectacle frame and first and second electrically-tunable lenses, mounted in the spectacle frame and having respective focal powers and optical centers that are determined by control voltages applied thereto. Control circuitry is configured to apply the control voltages so as to shift the optical centers of the electrically-tunable lenses responsively to the focal powers of the electrically-tunable lenses.
