This is interesting it’s a type of bionic eye which could help people with blindness caused by retinal disease. The device which works as an artificial retina has recently been given the go ahead after it proved successful in trials. Scientists have said it marks a major step forward in bionic eye technology as it proves that electronic implants can be used to restore sight. As the device is not cheap, costing around £50,000 it is thought it will only be available to private patients, however, it is hoped it will later be available on the NHS. The device works by fitting an implant along with a radio receiver and electrode pad which stimulate cells in the retina. Patients can then use the camera to see light, motion and colour, as well as making out large objects and being able to read large letters on a screen.
