01. Is eyesight the same in space? (A K2S Question)

From The Space Library

While in space, some astronauts have noted that their vision changes a little bit—that they don't see quite as clearly as on Earth. This has never proved to be a problem that limited anyone's duties, or affected their performance, and no one has been able to diagnose a reason for this.
