Can you see all 12 black dots in this mind-bending optical illusion?
Eye-watering puzzle is breaking the internet and it might just break your brain at the same time
IF you thought Kim Kardashian's bum had a devastating effect on the internet, then you've clearly never seen what happens when an optical illusion goes viral.
Now another strange visual puzzle is setting social media alight after causing viewers to suffer an "existential crisis" when they can't see 12 dots all at the same time.
"'How can I ever know what the truth is?'"
The illusion happens when the brain guesses what's going on in the image as you stare at just one part of it.
The dots are placed at the intersection of several grey lines. When the eye sees this intersection in its peripheral vision, the illusion of a small, faint square is created.
"That can counteract the blurry black dot that is actually, physically there," Arnold added.
The optical illusion was first posted to Facebook Japanese psychology professor Akiyoshi Kitaoka over the weekend and is based upon a similar puzzle from an academic paper published in the journal Perception back in 2000.
