Why astronauts’ lower eyelids rise in microgravity

Researchers reviewed 115 NASA photos from 13 astronauts and found an average 1 mm decrease in MRD2.
All astronauts surveyed showed signs of reverse ptosis, with 62% showing changes greater than 1 mm.
The study proposes cephalad fluid shift and elastic recoil of facial tissues as the main causes.
