That should be enough to reduce the chances of whiplash, and the tears might not
completely boil away before they could get back into a pressurized environment.

Yeah...but the zero pressure can make your eyes pop out and stuff like that
after a while.

Not before they freeze, and even that will take a while (contrary to popular
belief, while vacuum is extremely cold, without any matter to convey the heat
away, it does take a while to achieve freezing temperatures). There’s not a lot
of air inside the human body, and nearly all of it is found within the lungs.
They can and will rupture if you try to hold your breath in a vacuum, but not
the eyes. The human body is actually more structurally sound than a Boeing 747,
and the only known significant difference between being exposed to vacuum and
being exposed to non-oxygenated air is that water will boil away at low enough
pressure. Either way you die of oxygen-deprivation, though you end up losing
some moisture first in a vacuum.

Thanks and PLMKWYT about the subject.

I believe I already did. However, if
you want to read real scientific accounts of what would, and what has, happened
in the event of human exposure to vacuum, try
this. Don’t
worry, there’s nothing gruesome or violent, and noone in the factual accounts
was actually harmed. Probably the most famous instance of vacuum exposure is
the one in 2001, where Dave has to clear the gap between his pod and the airlock
sans spacesuit. It should be noted that the book was written by Arthur C.
Clarke, who is not known for filling his books full of scientifically unsound
events. This anime version, however, while not scientifically improbably (aside
from the artificial gravity, which can currently only be generated by
centrifugal force), involves such a level of split-second timing as to be very
unlikely to happen without some sort of mishap that would prevent the successful
rescue, or at least require the ship to go chasing at least one drifting body.
And just what the heck would they have a rocket-propelled rope for anyways?
It’s not like this is the sort of event that would be part of the standard
training retinue.
