retinal prosthesis
A retinal prosthesis is a device designed to restore some vision to people who have lost their sight due to retinal diseases, like age-related macular degeneration or retinitis pigmentosa. It typically consists of a small camera mounted on glasses that captures images and sends them to a microelectrode array implanted in the eye. This array stimulates the remaining healthy retinal cells, creating visual signals that the brain interprets as images. While it doesn't restore vision to normal levels, it can help users perceive light and movement, improving their ability to navigate their environment.

Retinal prosthesis is a medical device designed to restore vision for people with certain types of blindness, particularly those caused by retinal diseases like retinitis pigmentosa. It works by converting visual information from a camera placed in glasses into electrical signals. These signals stimulate the remaining healthy retinal cells, enabling patients to perceive shapes and movement. While it doesn't restore natural vision, it offers a new way to gain some visual function, helping users navigate their environment and improving their quality of life. Overall, retinal prosthetics represent a significant advancement in vision restoration technology.
