Can You Spot All 12 Dots In This Puzzle That's Driving The Internet Nuts?

Remember back when the colour of 'the dress' left you scratching your head? Well, you're going to feel a similar emotion when you try to figure out what's going on in this optical illusion going viral.

Unlike other puzzles that expect you to find something, this illusion tells you exactly what you should be seeing. Created by Jacques Ninio and Kent A Stevens, the illusion comprises a sort of mesh. It also contains distinctly placed black dots, 12 in number, and all you have to do is spot all 12 at once. But can you?

The picture was posted on Facebook by psychology professor Akiyoshi Kitaoka on September 11 and has since been shared over 22,600 times. The image even made it to Twitter on September 12 and has been retweeted over 33,600 times and has more than 32,000 'likes.'

"Love it. It's hurting my brain," says one commenter on Facebook. "You just have to let your eyes unfocus. I saw 12 dots by letting my eyes just relax and not focus on the picture," explained another. "My wife can see all 12 just fine. Is she a witch? Please advise," tweeted one worried user.

Give it a try and tell us if you managed to spot all 12 dots at first glance.
