Abstract
An optical article that includes an ophthalmic lens that includes a substrate, a first layer comprising liquid crystals being disposed on at least part of the substrate, and a first and a second electrode made of a conductive material, and a voltage source electrically connected to the first and second electrodes and configured to control an orientation of the liquid crystals depending on the voltage applied. The ophthalmic lens further includes a second layer made of photoconductive material placed between the electrodes, and the optical article further includes a light projector configured to project a light pattern on the second layer of the ophthalmic lens, the second layer being locally conductive when illuminated by the light pattern, the light pattern corresponding to a pattern of refractive index modification to be induced by the liquid crystals of the first layer.
