A BRAIN-BOGGING optical illusion twists celebrities’ faces to make them appear distorted and alien.
In a recent TikTok video, user @professoramx highlighted the trick that requires you to stare at a cross between two faces.
That puts the A-listers – which include billionaire Elon Musk and British actor Daniel Kaluuya – in your peripheral vision.
The famous people in view change every second or so, altering your perception of their facial features.
“This video will show you just how trippy your eyes can get,” the influencer said in the post uploaded Sunday.
“I want you to stare at the plus sign in the middle of the two faces. Just focus your full attention on it.
“As you rest your eyes, the faces left and right will morph into some trippy, alien-looking figures.”
Professoramx, who has more than 100,000 followers on TikTok, posts videos about fun visual puzzles for you to try.
Some of his videos have been viewed millions of times.
According to TikToker, the illusion is the result of something called the “Flashed Face Distortion Effect.”
This is a famous visual effect that occurs when faces are presented rapidly in someone’s peripheral vision.
Researchers have shown time and time again that this makes the observed people look more and more grotesque.
“Our brain compensates for the lack of visual information by filling in facial features,” Professoramx said.
“It ends up looking kind of crazy.”
Optical illusions are often just a bit of fun, but they also have real value for scientists.
The brain puzzles help researchers shed light on the inner workings of the mind and how it reacts to its environment.
As early as 2017, scientists Kim Ransley and Alex O. Holcombe from the University of Sydney emphasized the importance of illusions in our understanding of the brain.
“Visual illusions show us that we have no direct access to reality,” the couple wrote in The Conversation.
“They can also provide a glimpse of the mental processing that provides our experience of the visible world.
“In fact, the processing in our brain is the basis for many illusions.
“Rather than providing information from our eyes in near-raw form like a camera would, the brain tries to determine what’s actually out there.
“When the information coming into the eye is ambiguous, the brain has to make educated guesses.”
It follows the release earlier this month of a spooky illusion that makes viewers feel like they’re falling into a black hole.
