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
Yes.
The instructions say don’t cross your eyes but that’s horseshit and probably why so many people fail to see them.
My method is to cross my eyes, then uncross them slowly until the 3d effect appears, then hold on that position.
