If you can find all ten you definitely have 20/20 vision and a high driving IQ.

Although it may seem simple, this is no easy feat, and the average person can only find eight of the differences.

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

This illusion is made particularly tricky through the varying shades of vibrant colours in the background.

The absolute chaos in this school bus scene – with children waving their arms around, holding a bunch of miscellaneous objects, wearing every colour in the rainbow – means that your eyes find it hard to focus.

The subtle differences are barely noticeable as a result, so only people with impeccable vision are able to find all 10.

Benefits of Optical illusions

RESEARCHERS have developed many tests that show how various brain regions react to optical illusions.

They are not only entertaining, but they also shed light on how our brains interpret visual data.

By giving your brain a little workout regularly, you enhance your ability to focus and observe details.

Studies have shown that people who regularly challenge themselves with optical illusions and puzzles improve their problem-solving skills, concentration and attention.

Improved concentration and attention span, in turn, can help prevent cognitive decline in older age.

Psychologists at The University of Glasgow found that staring at an optical illusion can improve eyesight by allowing you to see small print.

Have you found all of the differences yet?

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

If you found this puzzle too easy, try some of our other brain teasers.

Test your vision by trying to spot the sneaky frog hiding amongst the woodland floor full of hundreds of leaves in this image.

Only the top 9% can find it within 12 seconds!

Or test your IQ by trying to find the cheeky monkey camouflaged somewhere inside a giraffe enclosure.

If you can find it within 15 seconds you might have 20/20 vision – but, it’s not that easy.

This illusion is created to test your observational skills.

You can also try and spot all five differences between these two identical pictures.

If you couldn’t find all of the differences between the two school buses, don’t worry, we have the answer for you below.
