A bionic eye is a type of visual prosthetic designed to restore vision for individuals with severe vision loss or blindness. It typically consists of a camera mounted on glasses that captures images and sends them to a small device implanted in the eye. This device stimulates the retina or the optic nerve, allowing the brain to interpret visual information. These devices are often developed for conditions like retinitis pigmentosa or age-related macular degeneration. While bionic eyes do not provide perfect vision, they can help users detect light, shapes, and movement, improving their ability to navigate their environment.
