Abstract
Optical apparatus () includes a transparent envelope () configured to be mounted in a spectacle frame. An electro-optical layer () is contained within the envelope, with an array of transparent excitation electrodes () disposed over a first surface of the transparent envelope. A transparent common electrode () is disposed over a second surface of the transparent envelope, opposite the first surface, and is electrically separated into a central region defining an active area () of the electro-optical layer and a peripheral region, which at least partially surrounds the central region. Control circuitry () holds the central region of the transparent common electrode at a predefined common voltage while allowing the peripheral region to float electrically, and to apply control voltage waveforms to the excitation electrodes, relative to the common voltage, so as to generate a specified phase modulation profile in the active area of the electro-optical layer.
