visual prosthesis

A visual prosthesis is a medical device designed to restore vision in individuals who have lost their sight, typically due to conditions like retina damage or diseases such as age-related macular degeneration. These devices work by bypassing damaged parts of the eye or brain. For example, a common type involves placing a small camera on glasses that captures images and sends signals to an implant in the eye or brain, stimulating visual perception. While these devices are still in development, they offer hope for improved quality of life by helping individuals perceive their surroundings again.
