Spotting the four deer in just 11 seconds can show you have sharp vision and intelligence

If you can find the four deer in this picture in less than 11 seconds, you might have a high IQ.

Those who manage to solve this challenging optical illusion quickly could proudly claim to have perfect vision.

In this picture, you will see a heap of ordinary rocks and debris.

At first glance, it might seem like nothing else is going on in this photo.

Therefore, players have been challenged to test their eyesight and seek the four deer hidden among the rocks.

This optical illusion is tricky as the deer are nearly the same colour as the rocky scene.

Therefore, they have seemingly camouflaged into their background.

Many animals use this as a way to protect themselves from predators in the wild but can you see past their tricks?

Here is a clue for players who might be running out of time.

Focus on the centre of the image and you might spot a pair of eyes looking back at you.

Here is another hint for viewers who might need one.

All four deer are close to each other.

If you cannot find all the creatures, do not worry as you can scroll down for the answer.

Optical illusions can also be a great way to test your senses and mental cognition.

They can force people to look past clear and obvious images.

This process can help to stimulate several parts of the brain at the same time.

Time limits can also help players to act quickly and improve their focus in stressful situations.
