Your peripheral vision is part of your overall field of vision, which is about 190 degrees. However, it is far from perfect and sometimes it makes us see things that don’t really exist. We found a great way to prove it to you.
All you need to do is focus on the cross in the center of the image below, without looking the other way.
You will notice how your peripheral vision turns the faces of ordinary people into ‘monsters’.
The faces begin to become distorted, right? And the more we look at the center of the image, the greater the distortion.
Why does this happen? We will explain everything steps by step.
There is an area of our retina that is called a yellow spot. It contains the largest number of receptors in the eyeball, thanks to which we can see a certain area more clearly.
Let’s call this the main field of view. It covers about 10% of the entire range of our vision and shows what our eyes are directly focused on.
In this case, our main field of vision is empty; There is only one dark area with a white cross.
The brain tries to obtain information from other sources located outside the main field, in this case, the alternate images on the left and on the right.
These sources are not very “reliable” and the brain tries to combine them into one image.
You are also trying to process the photos in no time, as the images change very quickly.
As a result, the ability to discern faces is lost and the brain simply combines different multi-faceted resources into a single whole. So we end up seeing ‘monsters’!
