You're having *leaks* around the cushion that is what's blowing into your eyes.
are you using a mask liner?
At my last sleep study I complained of the same problem to the sleep tech so she told me to cup my hand over the vent holes briefly to see if it was a leak or not. I do this often and it does seem to be the vent holes. I tend to sleep with my head down a lot.
