KEY HIGHLIGHTS
- Our brain tries to make sense of a plethora of visual inputs presented to it.
- Sometimes the scale at which you perceive an image can determine whether you understand it.
- An optical illusion is a great tool for psychology researchers to understand the inner workings of the human mind.
One of the easiest ways to spot a celebrity is to step away from your screen. The further away you go, the clearer the face usually becomes. Some other tricks that will bring out the image include shaking the device you are viewing it on as well as standing at an angle.

It’s a refreshing take on Magic Eye illusions, which used swirls of dots or lines to obscure a 3D image, according to a UK-based news outlet.

He compared it to another optical illusion of the same class, a monochrome lattice illusion that hides the image of a panda.
“Our eyes encode vast amounts of messy sensory information, and our brains use clever tricks to decode that information to try to make sense of what we’re seeing,” says Dr. Kuhn.
“The panda image has a certain spatial frequency when it’s a certain distance from you,” she said. The closer the image is to you, the lower the spatial frequency, and the further away it is, the higher the spatial frequency.”
“In short, the farther the image is from you, the more black and white lines fall on the light-sensitive part of the back of your eye.
Optical illusions are not just a recreational puzzle, they actually have a scientific application.
The brain puzzles help the researchers shed light on the inner workings of the mind and how it reacts to its surroundings, according to ANI.
