Smith, a researcher in the Biomedical Research and Environmental Sciences Division at NASA Johnson Space Center in Houston, TX, explains: "We've identified a genetic link in astronauts with vision issues." He and his colleagues discovered that two significant genetic differences can affect astronaut vision. The differences influence enzymes that direct an essential biochemical process in cells.
