Can exercise, swimming goggles help protect astronauts against spaceflight-associated changes to eye, vision?

(JAMA Network) Astronauts on long missions at the International Space Station can experience changes to their eyes and vision that can last for years. This study included 20 men who on three separate days at NASA's Johnson Space Center in Houston completed exercises while on their back and tilted back head-first (to simulate the effect of exercise in space); 10 of the participants wore swimming goggles.
