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
Tried various distances, that didn’t help too much. I’m afraid I have to hold to the theory that I’m officially old now and need bifocals.
