Special Operations have the same restriction...in addition to G's there are concerns about blast-overpressure from explosions or slipstreams peeling the flap off. Also any wound is more susceptiple to DCS for divers...just what you need, little nitrogen bubbles under your corneal flap

bet that would sting a little
