Eye changes from Spaceflight Compared to Simulated Weightlessness

Some astronauts who fly long missions to the International Space Station experience eye changes. This study investigated whether the eye changes from the traditional spaceflight analog (an experience on earth meant to mimic spaceflight) of simulated weightlessness from 30 days of bed rest with head tilted down were similar to those experienced by astronauts during spaceflight.
