You could have 20/20 vision if you can spot the flies among the spiders in this creepy Halloween illusion in 9 seconds

YOU might just have 20/20 vision if you can spot the seven flies among the spiders in this creepy Halloween illusion in nine seconds.

However, a race against the clock will only add to the difficulty of this task as you frantically search for the hidden insects.

Not only do you need razor-sharp eyesight to single out the tiny critters, but you must also have incredible observational skills.

That's because you need to really focus in order to identify the handful of flies among the hundreds of spiders.

If you don't, then this latest brain teaser could leave you pulling your hair out as you struggle to beat the clock.

In the photo provided by The Dudolf, there are also five pumpkins and a cat, just to make things even more difficult.

But don't let them distract you from the main objective.

By making sure that you check every part of this photo, you stand a higher chance of succeeding in finding all the flies.

Just like with other optical illusions, it's crucial that you leave no stone unturned.

If you can do all of this, then you should be able to find all the flies in nine seconds.

As a result, that means you must have 20/20 vision.

If you are struggling to find the flies, then one clue is to look for the small circles with two wings on either side.

Once you locate one, you'll be able to locate them all.

If that was too easy for you, then you may fancy having a go at one of our other optical illusions.

If that's the case, then try and spot the hidden rabbit in the rocky scene in under 10 seconds in the image above.

The image has left thousands of adults confused and frustrated as they fail to find the well camouflaged animal.

This latest optical illusion has been designed to really put your skills to the test and only the most composed people will succeed.

But if you're able to locate the rabbit, you must have 20/20 vision and a high IQ.
