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.
I first looked at a pic on my phone and it worked so i thought it would look even better if I put it on my tv. Did that and I wasn’t able to get it to work, googled something like “can’t see magic eye on large tv screen but can on phone” and apparently it’s a lot more difficult on large screens. Or maybe you just are old lol
