Optical illusion with woman's hidden face can only be seen by 'people with high IQs'

We often come across optical illusions that require some brain power - and this one is no exception.

From different shapes to colours and whether or not the lines are actually moving, it takes a lot to try and see what's actually happening. Some illusions are pretty tricky however and to understand what's actually going on meaning you'll need to be extra focused.

One such illusion was found by the Daily Star and according to PinkVilla who shared the Instagram image, it is one that can only be worked out quickly by those with high IQs or sharp eyes.

Whilst looking at the image, you should be able to spot the face of a lady. At first it may take a while to get used to with all the lines and you may even feel a little dizzy. But if you were able to find the hidden lady within 10 seconds, you've got a bright mind.

You can see the optical illusion below. But can you do it within 10 seconds? Time yourself!

If you want another challenge, one test asks viewers to find the hidden potato in an image full of cartoon hamsters. It was designed to work our observational skills as well as intelligence, and the task is to find it within seven seconds.

Another animal-themed illusion that puzzled our readers recently was one in which a panda bear was hidden amongst pills and other medication.

The placement and colours of the picture's different parts makes this one particularly hard to crack. But if you can spot the bear within 12 seconds, your observational skills are excellent.
