I’m calling bullshit on this one, cause radiation does not have an effect on the eyes unless exposed for more than 30 minutes or so, and most of radiation does not get though the Van Allen Belt and at the time being the ISS (where the astronauts go to for the missions) is under the Van Allen Belt and most of the time the people are not looking out the windows and are instead they are working on the missions/experiments that involve being away from the windows and when they have to go outside their space suits protects them from what little radiation that gets though and their helmets have two visors, and the outer visor stops damage to their face as well as their eyeballs. The gravity that they experience does not effect much and when they get out of Earth’s gravity and the rockets come of the G-force stops and their eyeballs and their faces go back to their original shape cause of the blood flow and the fluid that’s inside humans, so before you post anything else I suggest you look up human biology first and study it through and through!

Fighter pilots and bungee jumpers are only subject to gees for short periods. Their body parts aren’t stressed long enough nor often enoughto have any significant effect on growth.

I would think that high proportions of Astronauts with military flight backgrounds and the high-G training that all mission crew members undergo, might be a factor here. I agree with the authors that comparison testing against program members who have never been to orbit, and military pilots in general, is necessary before drawing any conclusions at all.
They also might want to see where frequent Bungee jumpers fit into the pattern.
