Tiny “solar panels” implanted into the eye could one day restore vision to the blind without the need for any ugly wires. Around 15 million people worldwide have some form of blindness. In people with these conditions the retina’s photoreceptors, which transform light hitting the eye into electrical impulses, are often damaged, preventing visual information from being sent to the brain. Several companies, such as Second Sight in Sylmar, California, have developed prosthetic retinas, some of which are currently in clinical trials. Such technologies generally use a camera to detect visual information that is then relayed through a wire to an implant inside the eye. The implant effectively replaces the damaged photoreceptors. However, these prostheses tend to require numerous wires to connect the implant to an external power source and to transmit information from the camera to the implant, says James Loudin of Stanford University in California.
