Research shows that our brains can understand various images and perspectives, though they can be tricked by optical illusions that play with our perception.

Optical illusions come in different types—physical, physiological, and cognitive. These illusions trick our minds and give us a glimpse into the complex workings of visual perception.

Solving puzzles like this one is great for improving your focus and attention. This practice has been around since the times of ancient Babylon.

This particular image started as a puzzle for children. It shows a scene in a restaurant where a wallet has gone missing.

In this optical illusion, a man and woman are enjoying a meal when the man notices that his wallet is gone. The waiter starts to suspect something as well.

Take a close look at the image and see if you can find the hidden wallet somewhere in the restaurant scene.

Even though it might seem tricky at first, if you examine the image carefully, you’ll notice that the wallet is cleverly hidden behind the woman’s hair.
