Abstract
Embodiments disclosed herein relate to systems including at least one ophthalmic device and methods of using the system. The ophthalmic device includes at least one switchable lens therein that includes at least one electro-optical material. The ophthalmic device also includes at least one charging electrical circuitry. The charging electrical circuitry is electrically coupled to the switchable lens and is configured to receive electrical energy from or provide electrical energy to the switchable lens. The ophthalmic device can also include at least one transfer electrical circuitry that can be coupled to and configured to transfer electrical energy between the charging electrical circuitry and the switchable lens. The ophthalmic device can also include at least one controller operably coupled to at least the charging electrical circuitry and the transfer electrical circuitry. The controller can be configured to at least partially control the charging electrical circuitry and the transfer electrical circuitry.
