Understand the optical illusion behind this test

Start by looking at the image below:

In this optical illusion challenge, people are tricked into trying to identify the black dots in the image above. However, the great difficulty is being able to visualize them at the same time.

Although this test does not reveal your personality traits, it can move your brain and test your reasoning. Therefore, it is important for you to assess your ability to solve this challenge. What do you see first? How many black dots did you see?

It is worth remembering that it is practically impossible to see the 12 points at the same time. The most that a person reported that he could see until today was 5 points.

Understand why optical illusion occurs

The optical illusion occurs in this image due to what experts call human peripheral vision. When analyzing the test, when you focus on a point, you can see it, however, when you direct the vision to another point, you fail to see the previous one.

This happens because humans do not have good peripheral vision, but rather directed and focused vision. That is, they cannot have a vision around everything around them. Thus, this circumstance allows the creation of the optical illusion.
