Optical illusion: find the number 5 in 10 seconds.

Optical illusions are attractive because they show how human perception varies from person to person and provide a small demonstration of the variety of ways we perceive the outside world through our senses.

Here's a number-based optical illusion that tests your speed and visual acuity, as well as your spatial orientation.

What is an optical illusion?

An optical illusion, also known as a visual illusion, occurs when your visual perception is "tricked" into showing or hiding images that differ from what is considered "reality." Simply put, an optical illusion occurs when we are able to perceive or distinguish a scene or image that we have seen with our own eyes. We easily interpret or are misled by an image or scene we see without noticing the details or the big picture, and this distorts our perception.

Because it is difficult to correctly identify images containing optical illusions, they are popular, and deciphering them is a task that many find fun and interesting.

But learning optical illusions also increases the efficiency of the brain and eyes in developing observation skills.

Test the limits of your perception by trying to identify the number 5 in this image in just 10 seconds.

How to continue?

Look closely at the picture for 10 seconds, looking for the number 5. Few people can identify the number 5 in the first 10 seconds, but most people can if they look at the picture for a longer period of time.

The image below contains the answer. The area highlighted in red is the number 5, which you should have identified within the first 10 seconds of viewing the image.

Don't worry if you didn't notice the figure, many don't, but the more optical illusions you solve, the more you will train your eyes, brain and reasoning skills.
