Electrowetting opthalmic optics including gas-permeable components

An eye-mountable accommodation device comprising:

• an electrowetting cell comprising:
• first and second optical windows, each having an inside surface and an outside surface and joined around their perimeter to form a sealed enclosure between the inside surfaces of the first and second optical windows,
• a first gas-permeable electrode formed on the first optical window, the first gas-permeable electrode comprising an electrically conductive layer and at least one dielectric layer, the electrically conductive layer being sandwiched between the first optical window and the at least one dielectric layer,
• a second gas-permeable electrode formed on the second optical window, the second gas-permeable electrode comprising an electrically conductive layer,
• an oil layer positioned in the sealed enclosure so that the oil is in contact with the inner surface of the first optical window and with the first gas-permeable electrode, and
• a saline solution layer positioned in the sealed enclosure so that the saline solution is in contact with the oil layer, with the inner surface of the second optical window, and with the second gas-permeable electrode,
• a protective coating surrounding and completely enclosing the electrowetting cell;
• a contact lens material, distinct from the protective coating, surrounding and completely enclosing the protective coating;
• and
• control electronics mounted on the contact lens material and electrically coupled to the first and second gas-permeable electrodes.
