(CNN)--NASA has something new to consider regarding long-term space trips.

It seems astronauts are suffering vision problems after spending time aboard the International Space Station.

Astronauts have reported blurred vision after spending prolonged periods of time in space.

And research shows, the more time they spend in space, the more likely they are to have problems.

NASA says it is further investigating the issue.
