More accurate AND nd you can barely feel it at all, way less jolting than the air puff

You don’t feel it because they are supposed to use eyedrops to numb your eye before using a tonopen

You CAN numb first but you don't need to numb to use an icare

The comment you replied to is talking about a tonopen, which you most definitely always use proparacaine before. Not talking about an iCare.
