ScienceCasts: Horn-rims and Funny Stockings on the Space Station

About three quarters of ISS astronauts experience changes in the structure and function of their eyes. An experiment on the space station called the “Fluid Shifts Study” is investigating these vision problems in space.

So I gather that spending time in space can cause farsightedness? I don't suppose you could send s nearsightedness person to space to see if they come back "cured"? Or are there too many other variables to contend with?

[@theJellyjoker]

What I 'm thinking would be great is an MRI (or some other equivalent device) on the station to get a look at the distribution of fluids in an astronaut during flight.

So I would have normal vision in space since I am nearsighted on earth?

[@danielsmith8171]

What influence does increased fluid pressure in the brain have on intelligence... as measured by IQ? Can near-sighted vision be corrected by increased fluid pressure?

Very interesting, Thankyou.
Just as well I'm too old & stupid to be an astronaut, I'm way too vain for glasses!

Kinds of reminds me of penguins and keeping their blood warm in the colder regions of earth.

This is a pretty significant thing to figure out a cure for if we are to colonize other planets. Good luck Mr. Stenger :)
