Abstract
An ophthalmic device includes a lens and an electronic component embedded in the lens to enhance the functionality of the lens. The ophthalmic device includes a first coil to wirelessly receive energy from an external device, such as a wireless charger, and wirelessly transmits the received energy to a second coil coupled to the electronic component so as to power the electronic component. The first coil can function as part of a repeater to facilitate the wireless charging. The repeater can receive electrical energy wirelessly and works with various positions, sizes, and shapes of the electronic component. The wireless power efficiency can also be increased using the repeater to concentrate a magnetic flux within the second coil.
