Artificial Retina - Science Nation

Kathy, blind for over 30 years due to retinitis pigmentosa, finds hope in an artificial retina developed with NSF support. The device, involving a camera and a chip implanted in the retina, helps her perceive light contrasts. Kathy is one of 20 patients using this technology, which is still evolving. Her journey involves learning to interpret visual signals, akin to a child's developmental stages. The technology promises a future where higher resolution chips could allow users to recognize faces. Kathy hopes this advancement will benefit future generations, including her descendants.
