Visual prosthetics are devices designed to restore vision for individuals with severe visual impairments or blindness. These devices work by converting visual information into electrical signals that stimulate the remaining healthy cells in the retina or the visual cortex of the brain. Examples include retinal implants and cortical visual prostheses. The technology behind visual prosthetics is continually evolving, with research focusing on improving image resolution and user experience. Companies and institutions are developing various prototypes, such as the Argus II retinal prosthesis, which has shown promise in helping users perceive light and shapes, enhancing their ability to navigate their environment.
