Retinal implants are medical devices designed to restore vision in individuals with certain types of blindness, particularly those caused by retinal diseases like retinitis pigmentosa. These implants work by converting light into electrical signals that stimulate the remaining healthy cells in the retina, allowing the brain to perceive visual information. The technology typically involves a small camera mounted on glasses that captures images. These images are then processed and sent to the retinal implant, which directly stimulates the retina. While retinal implants do not restore normal vision, they can provide users with a basic sense of sight, helping them navigate their environment.
