There's some possibility of the pressure point working, but there's also an ingrained reflex effort to protect the eye which has a decent chance of convincing them to move their head back even if it doesn't hurt at all.Yeah, to me the most questionable part is moving the head back with the pressure points under the cheekbones. Those hurt if you're standing still so they can get good pressure on them. I highly doubt they're much accessible in the chaos of an actual fight, nor do I think most people in a fight would give in to the pain without doing something in response.
