Optical illusions are purposefully designed to trick our vision, and can be used as simple determiners of intelligence.

Psychologists at The University of Glasgow found that staring at a brainteaser like this can improve eye sight by allowing you to see small print.

And according to ZenBuisness: “These visual puzzles can give you a good mental workout that can, in turn, help you think more efficiently and solve problems more easily.”

They are widely regarded to help improve our attention spans, concentration, and overall cognitive abilities.

Optical illusions where you have to find an image within an image aids your brain’s ability to interpret ambiguity.

It helps to keep your brain sharp and young.

This puzzle is made particularly tricky through the varying, bright colours in the background of the image.

If you’d like some help, try breaking the image down into several sections. Then search each section slowly, one at a time.
