Oh they're real, and once you can do it well, you can put 2 of those 'find the 10 differences!' pictures side by side and the differences pop RIGHT out at you, it's like cheating
Only works if you have 2 eyes. Easiest way to explain it, is to keep reading and focusing on this (assuming its a monitor 2-3 feet away and not a phone), while doing that and not averting your gaze, put up two fingers about a foot in front of you, like you're using 2 hands to make a goalpost for a paper football
If you're still reading this, play with your focus a bit to make 3 perfect fingers out of 2.
If that worked, somehow do the same for the picture, but instead of using a finger for a reference point, use the repeating pattern (like the eye below), almost like you're ignoring the monitor and focusing on something a few feet behind it. Hope that helps...someone lol
