Who's been doing this since they we're maybe 7 years old :)
- tobr 2y agoChecking in! I’m frequently baffled by how unaware most people seem to be about the absolute basics of how their eyes work. Like, people don’t even seem to be aware of how their stereo perception is largely made from two images, or any of the implications that has. I actively think about the two images maybe dozens of times per day.
- graypegg 2y agoChill out, that's a bit of hyperbole isn't it? This is just a trick for doing a spot the difference puzzle. It's not exactly a daily task most people are thinking about. Most people at least understand that stereographic vision has something to do with 3D perception because we've all closed 1 eye before.
- tobr 2y agoIt’s a useful way to compare visual things, which comes up in all kinds of contexts other than these puzzles.
- jeffbee 2y agoI figured everyone because I had a puzzle book that instructed readers to do this.
- knallfrosch 2y agoWe've had these stereoscopic books with hidden images and I never saw any. So I've been failing at this since 7 years old – does that count?
- lowdest 2y agoYup I used to do this with tile floors as a child.
