Why Does Vision Blur In Space? | Video

From the creator

It’s been known since the 1960’s that eyesight changes in space. Current studies on the International Space Station are narrowing in on the exact mechanisms. One hypothesis: When in microgravity (‘weightlessness’), an increase in inter-cranial pressure is transmitted to the eyes, changing their focus. Credit: NASA
