Here’s a clue, the dog is way bigger than you think.

Optical illusions are anything made to easily fool us through what we see.

Human curiosity means that solving these perplexing puzzles can bring us a great sense of satisfaction and not only that, but they are also good for our brains.

We’ve said before that pictures are more than just finding and playing – some pictures can actually improve our health.

Psychologists at the University of Glasgow have discovered that looking at an optical illusion can improve vision by allowing you to see fine print.

And according to ZenBuisness, “These visual puzzles can provide you with good mental exercise, which in turn can help you think more effectively and solve problems more easily.”
