An Artificial Retina is a medical device designed to restore vision in individuals with certain types of retinal diseases, such as retinitis pigmentosa or age-related macular degeneration. It works by converting light into electrical signals that can stimulate the remaining healthy cells in the retina, allowing the brain to perceive visual information. The device typically consists of a small camera mounted on glasses, which captures images and sends them to a microelectrode array implanted in the eye. This technology aims to improve the quality of life for those with severe vision loss by providing a form of artificial sight.
