OK guys, let me get this straight...
Are we talking about pulling out the vent (ie the surround) or the eyeballs vets (ie the crosshair round bit that you can move around and what I'll refer to eyeballs from now to really differentiate between the two).
I tried pulling my eyeballs out (

) but it didn't seem to work. Tried it with the coathanger trick, but they seemed awful tight, so gave up. Keep in mind I was yanking fairly hard.
As for the vents, if you get at it with a flathead screwdriver, to the eyeball vents come out with it? I was under the impression there was a screw or something that held the vent in place, and that screw was located behind the eyeball. In other words, you needed to remove the eyeball before you could remove the vent itself.
Suggestions? Corrections?
