Optical illusion and autosteograms

Optical illusions tend to trick the human visual system into seeing things that aren't there or seeing things differently.

The brain can capture and process some attributes of the image. However, there are other aspects that are misleading, thus leading to errors in the perceptual process.

With the advent of social networks, optical illusion became very successful among Internet users, as it is a fun way to exercise the mind. The See That Magic profile shared the image below on the TikTok app with the following caption:

“Look at the middle of the screen, put your nose to the screen and slowly back away. What number do you visualize?”

The illusion made available is known as an autosteogram – an optical illusion technique in which, the from two complementary two-dimensional images, it is possible to visualize an image three-dimensional.

A curiosity is that this technique, in addition to being used to transform normal images into three-dimensional ones, thus creating illusions of optics, also serves to make 3D glasses and special cameras – a camera capable of taking three-dimensional pictures, for example.

But what up, can you visualize the number? If not, the hidden number is 0 (zero). However, you don't have to worry if you can't see it, as many people can't either.

Share this illusion with friends and family and find out if they can see the number.
