Interesting

Their mothers told them not to do that or they would go blind.

I guess the question would be is that due to being in zero gravity for so long, or the exposure to sunlight without the benefit of the atmosphere to weed out the damaging rays.

Or something else?

Hope they find the answer - that’s a significant deterioration in eyesight.

2 liters of extra fluid inside your skull? Seems like that would give you a pretty bad headache.

[Bratch]

Uh-oh!

[nascarnation]

Wow you're right....

If you don’t spend a bit of time each day looking at infinity it would be shocking to me if your eyes didn’t adjust to focus on the nearby objects you are actually dealing with.

When “what you are looking at” is on the average about 5 to 10 feet away that is what your eyes are going to get good at.

Not much else to do when off duty...

Lack of gravitational pull on the body from BELOW is causing this problem. Going into space is going to present problems for humans. We really need a GOOD reason to go there instead of just wanting to spend billions and create jobs for people. Going in to space has not presented real benefits for the world.

If those billions had been spent on water projects, highway projects, rapid transit, electrical grids, etc....where would we be now? The money probably could have been spent in a better fashion causing a lot of more people to be employed on worthwhile projects.

LOL. 2 liters of extra fluid in your skull and your brain would squirt out the bottom of your spinal canal...

It’s not just astronauts, they need to look a lot more into post cataract surgery patients. I did not have astigmatism before it, now I do. And am having huge fluctuations in vision that won’t stabilize to the point I can get glasses to correct the bad left implant, sloppy surgeon chose wrong lens and nicked a nerve too. I’ve always seen blurred out of from day 1. A decade later the second surgery was better, different surgeon, TOP in Memphis, but now I see at 2 focal lengths. Hard to correct vision that changes every day or two. And my Peripheral vision has been ruined.

You are not told Lasix causes Dry Eye Syndrome or that Cataract surgery does too.

[Blood of Tyrants]

And your head would look like Charlie Brown’s.

[Blood of Tyrants]

No word in the article to whether the problem corrects itself.

[1_Rain_Drop]

well, that explains why real Aliens from outer space have big black eyes.

Change in gravity effects aqueous humor

I sometimes go to a website called Stuff Black People Don’t Like, and they have a saying there: You can have a base on Mars, or you can have a welfare state, but you can’t have both!
