The graphic shows how the technology works. There is an illustration of a patient with the implant wearing glasses with a built-in video camera and holding a processor connected by wire to the glasses. Below, another graphic shows how the camera sends images to the implant at the back of the eye, via infrared beam. A close-up of the eye shows the implant receiving those infrared images and then sending them on to a black hand-held processor. Red arrows highlight that the images are sent to the processor, enhanced and then sent back to the implant and on to the brain. A third graphic illustrates the way the images are enhanced. On the left is an image from the camera showing part of a word. The letters 'ernoon' are coloured black on a white background and appear slightly blurred. On the right is an enhanced image seen by the patient where the letters (now white) are bold and stand out against a black background.
