How Do Spaceflights and Long Term Planetary Missions Affect Vision?

Spaceflight can take a toll on astronauts’ vision, and researchers are working to understand why. Joshua Ong, M.D., a resident physician at the University of Michigan Kellogg Eye Center, highlights the visual challenges of zero gravity and what’s being done to address them on long-duration missions. This research is reshaping how we think about zero gravity eye care—read on to learn how Michigan Medicine is helping astronauts keep their sights set on the stars.
