  1. Devin Harris my understanding is with gravity, fluids are pulled out of your head and lower pressure lets your eyes keep their correct shape. In space, that fluid goes to your head and squashes your eyeball, pushing the optic nerve into the eye socket. Coming back to Earth doesn’t fix the eye’s distorted shape (not sure why not)
