Pilots and flight engineers experienced a simulated ascent to 22 000 feet, and subsequent short-term hypobaric hypoxia, in an altitude training chamber (each crew member underwent hypoxia for up to 3.25 minutes without supplemental oxygen). We measured their eye movements before and after hypoxia. Intersaccadic drift velocity increased after hypoxia exposure, suggesting that acute hypoxia diminishes eye stability.
