Scientists look to the sun for better-looking bionic eyes5/14/2012
In great news for the vision impaired -- and style conscious -- scientists may have come up with a way to make prosthetic retinas work without the use of cumbersome and unsightly wires. The synthetic photoreceptors work by sending signals from a camera to an implant inside the eye. Currently, a multitude of wires are used to connect the implant to both the camera and an external battery, but a team of scientists at Stanford University is now experimenting with using low-intensity infrared light transmitted through photovoltaic cells, similar to a rooftop solar panel, to send information to the receptors. The team is currently trialing the technology on rats and the results are, erm, looking good.
Do you think bionic eyes will become common in your lifetime?
