Astronauts are returning to Earth with dramatically altered vision after spending months aboard the International Space Station, and doctors are perplexed.

According to a recent report in The Washington Post, 80 percent of astronauts have seen their vision change in some way or another.

John Phillips, whose vision went from 20/20 to 20/100 after a six-month stint aboard the Space Station, was the first case recorded by doctors in 2005. Since then, several others have dealt with similar symptoms.

Visual impairment intracranial pressure syndrome (VIIP) seems to be the likely cause, although doctors are still trying to pinpoint it. This ailment occurs when there is more fluid in the skull when someone is in space rather than on Earth, which is due to the lack of gravity.

Doctors and scientists have been studying the phenomenon as they try to figure out a potential way of preventing it from happening in future cases.

Last year, it was reported that three companies were working with NASA to find solutions to vision problems http://www.space.com/28938-mars-mission-astronaut-vision-tech.html suffered by astronauts as humans plot a path to visiting Mars someday in the future.
