THIS mind-bending optical illusion challenges you to spot the hidden circles - but can you find them all in just ten seconds?
The hypnotising image has left the internet stumped as they try to locate the camouflaged shapes.
This illusion is named the "Coffer Illusion" and was created by a Stanford University psychologist in 2006.
A coffer is a decorative sunken panel used in architecture.
“First time viewers of this display invariable do not see the 16 circles segmented from the background,” wrote Anthony Norcia, who created the image.
“Rather, they see a series of rectangles that they frequently describe as ‘door panels’.”
The picture shows a mind-bending group of rectangles with a monochrome colour scheme.
It uses both horizontal and vertical boxes that easily blend into the background, making it hard to spot all of the circles.
The contrasting colours in this puzzle can be incredibly distracting but don't let that stop you from reaching the end goal.
Once you spot the circles in the puzzling picture, the image will play tricks on your eyes as you'll be able to switch back and forth between the two shapes.
Optical illusions are becoming a popular daily activity for puzzlers who want to test not only their eyesight but their brainpower too.
But don't worry if you're struggling, as we have the solution below.
If you focus on each quadrant of the puzzle, you'll be able to spot something suspicious.
And if this brain-teaser was too easy - or too hard - for you, then why not give these a go.
You could have 20/20 vision if you can spot this cat hiding in its owner's unkept backyard.
And if you're a fan of construction, they try spotting the glasses among the tools in this tricky brainteaser in less than 25 seconds.
Or, figure out if you're left or right-brained by counting how many watermelons you can see in this mind-bending illusion.
