It’s not really why he signed up to be an astronaut, but like it or not, Mike Barratt and his eyes have become a science project.

The eye charts he reads, the red drops that turn his eyes yellow and the ultrasounds being performed on him could determine whether he or any other astronaut ever journeys into deep space or sets foot on other worlds.

NASA’s new priority is how to protect astronauts from going blind on the years-long trip to get wherever they are going.

“I absolutely agree that this is our number one priority,” Barratt said.

Why?

Because when Barratt blasted off to the international space station, he needed eyeglasses for distance. When he returned to Earth, his distance vision was fine, but he needed reading glasses. That was more than two years ago. And he’s not getting better.

...continued...
After just six months, he went from nearsighted to farsighted. This is one of the many obstacles preventing a manned mission to Mars (minimum of three years).

very interesting. Though females being unaffected in space and males having issues is what's most interesting to me. We men were bound to be inferior to female in some way lol
