Astronauts in space are exposed to a newly identified medical condition, something that NASA should consider seriously. It is the blurring vision of some of the astronauts who have spent months in space that has made NASA to think about possible impacts it may have on long-term space trips.
According to NASA researchers, if astronauts stay in space for long period of time, the risk of blurred vision increases. Doctors are worried that long space travels, such as a multi-year trip to Mars, may end up blinding the space explorers.
In response to the serious threat, NASA has asked a number of researchers to study the issue and has also sent special eye-glasses to the International Space Station to help those affected, Los Angeles Times reported.
NASA has done a survey on 300 astronauts and found that almost 30 percent of those who have flown two-week shuttle missions, and 60 percent of those who have continued to stay for six months longer in the space station noticed things became blurry either during or after the missions.
