Me too! It's called tonometry.
The pressure check by blowing in wind, I find totally intolerable, since I had spinal surgery.
The other pressure check is a walk in the park in comparison, drops go in eye (at least 100 times better than dilating retinal photography ones.) There is usually a touch of fluorescein dye in them, so tissues look yellow.
For me, I know when the anaesthetic takes because I feel very tired, my eyelids get really heavy. It goes quickly.
A 'chin lamp' is used to do the test, and I've never known that it's being done. From my experience, I whole heartedly recommend it. I will NEVER have the wind test again. I've waffled on a bit, sorry.
Edit: Have only ever had it done at the opticians.
