This Perplexing Optical Illusion Have Taken The Internet By Storm!


Optical illusions are quite popular among the young as well as the young at hearts. Here’s a new optical illusion that has gone viral on the internet claiming that the dots on the intersections of the gray diagonal lines cannot be seen at once. It will also delude you that the dots are moving.


Look at the picture! Can you see the dots at the joints are moving? Well, this is why it is called an optical illusion. The dots aren’t going anywhere as it is a still picture with 12 dots altogether.

We have seen such pictures that create illusions and make us believe that the picture is moving. But this one has grabbed eyeballs all over right after it has been posted on Twitter. It says that you cannot see all the 12 dots at once, though you might know the total number of dots. You can see three dots at once.

Right after being shared on Twitter on Sunday by Will Kerslake, a game developer, this image became the top of Reddit on the next day. It received almost 2,600 comments and 8,200 upvotes.

So what is actually happening in this photo? Here’s the scientific fact behind your illusion. There was a study in October 2000 which explained this phenomenon somewhat like this.

“When the white disks in a scintillating grid are reduced in size, and outlined in black, they tend to disappear. One sees only a few of them at a time, in clusters which move erratically on the page. Where they are not seen, the gray alleys seem to be continuous, generating grey crossings that are not actually present.”

The paper in which it was published was called Variations on the Hermann Grid: An Extinction Illusion. A Redditor has shared this information.

Although the paper doesn’t have any absolute answer for this but it seems that the illusion is happening due to the “crowding” or “the inability to recognize objects in clutter,” and also the deficiencies in the way our memory works when we stare at something.
