Eye pressure during tattoo

Hi! Can't find info on this anywhere else - but the most painful part of my nanobrow process was the artist's pressure on my eyeballs. I was SO surprised she didn't warn about this, but then said it was normal. If I had been wearing contacts, that would have been a problem.

Is it normal? My eyeballs were being pushed against to the point of blurred vision, flinching, and lingering eyeball pain for several days. I'm scared to get a touch up!
