Astronauts on the International Space Station are not allowing vision issues to keep them from completing their important tasks on the orbiting laboratory. In fact, they are taking advantage of the opportunity to study why weightlessness alters vision.Even after 50 years of human spaceflight, scientists still are making new discoveries about human health in microgravity. New research points to a permanent vision risk for astronauts living without gravity. A large part of the International Space Station’s mission is to use this data to design future studies to mitigate, and hopefully eliminate the dangers. To see more details visit, www.redorbit.com
