"The new study, of more than 300 astronauts in the U.S. space program, found that almost 50 percent of those who served on long missions -- six months or more -- reported experiencing new problems with their ability to see objects near to them while in space and for some time after returning to Earth. Roughly 23 percent of astronauts who spent shorter periods in orbit reported problems with their near vision during their missions and after getting home."
Yikes! I hope we can find a solution for this. Otherwise, we will not be able to see what we discover when we go venturing away from the planet.
Studying this and other space health issues should be something we are doing on the International Space Station. After all, we don't even know what the health effects are for someone staying in space for as short as two years. Hey, NASA, let's put some money into this please.
