As a not quite middle aged dude, I only just now figured out how to see magic eye stuff. I tried a couple times in elementary school but didn’t get it so I stopped. Had a few drinks earlier, stumbled on some magic eye pic that I could see clear as day and it blew my mind a little
I can view the convergent (cross-eyed) ones no problem. I managed once to focus on the divergent ones with like 30 minutes of practice, but I had trouble focusing normally afterwards for like an hour so I haven’t tried since.
Ya I was wondering the whole time if this was going to cause some long term damage
It’s a skill. You get better with practice.
