How do you see the circles in the image?
"The concentric circles seem to be entangled." It is the phrase that accompanies the last tweet of Akiyoshi Kitaoka, professor of psychology of visual perception and illusion at the Ritsumseikan University in Kyoto (Japan). More than 1,800 retweets and almost 5,000 likes have viralized the image.
Even if it looks like it, they never cross!
If you observe it for the first time, the feeling is that both circles are intertwined, but look carefully (carefully, the image can get a little dizzy): at no time cross, is an optical illusion.
It is an effect similar to that created by the Italian psychologist Baingio Pinna in 2002 with his 'false interlaced': the circles seem to form a spiral, but they are only an ordered set of concentric circles. The illusion is due to the fact that the two circles are formed by small squares that alternate in color and inclination, giving a false sense of spiral.
Here with the most visible circles:
Amazing as an optical illusion plays tricks on our vision.
