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. I can change my vision’s focal point and focus distance at will, so it’s usually easy even though my eyesight is getting fucky with age.
