A vision prosthesis is a medical device designed to restore or enhance vision for individuals with severe visual impairments or blindness. These devices can include retinal implants, which are surgically placed in the eye to stimulate the retina, or wearable technology that helps users navigate their environment. The technology behind vision prostheses often involves advanced electronics and sensors that convert visual information into signals the brain can interpret. Research in this field is ongoing, with the aim of improving the effectiveness and accessibility of these devices for people affected by conditions such as retinitis pigmentosa or age-related macular degeneration.
