Visual Prosthetic

A device or system that provides visual information to people who are blind or have severe visual impairments through alternative sensory channels or direct neural stimulation. Visual prosthetics range from smartphone apps that convert visual data into audio or haptic feedback (like object detectors and navigation aids) to implantable devices that electrically stimulate the retina or visual cortex. The term emphasizes that these technologies function as a functional replacement for vision, helping users perceive and interact with their visual environment.
