Researchers have developed some light-sensitive chips, placed at the back of the eye to help people with visual problems. The chips are sending an electrical signal, converted from light, to the brain via nerve cells, but the problem is the chips are flat and the eye’s lens project images on curved surfaces, so it’s not possible to work.Fortunately an optical engineer from the University of Southern California, Michelle Hauer come with the idea to plant a camera on the eye, excepting the retina. Then, the recorded images will be sent to the chip at the back of the eye via a wire. Also she and her colleagues have designed a small enough camera that fits on the eye’s lens.

They seem to have solved all problems and might realize the project. Other problem was the need of energy, that has been solved with a wireless-charged battery, by induction.
