Most optical illusions confuse the human brain by using color and movement.

A TikTok account titled @coachly.de showed this to be the case with a post about an optical illusion.
“This is one of the best optical illusions I’ve ever seen, it shows you can’t trust your brain,” a male voiceover narrates in the reel.
In the video, users can see two circles next to each other with bright and colorful borders.
Inside the circles are small gray arrows that change direction.
When you look at the circles, they appear to move up and down or away from each other.
However, as the TikToker points out, this is not the case.
“Circles don’t move and they don’t grow or shrink either.”
“You can test this by covering the edge of the circle with your finger and you’ll see that it doesn’t change position.”
How does it work
This optical illusion works by tricking our brain into seeing movement through the use of contrasting colors.
Because our brain interprets a change in light as a change in movement, it appears that the circles are changing position.
In reality, however, they remain completely calm.
Viewer Reactions
Since it was posted just over a month ago, the optical illusion video has garnered more than 100,000 likes.
Many of the account’s 229,000 followers were stunned, with several thousand taking to the comments section to express their thoughts.
“I see them moving and not moving at the same time…” wrote one TikTok user, adding a series of “shocked” emojis.
“At first I thought it was moving, pause the video, it’s not a cap,” another confused user chimed in.
“Oh I see, I wanted to cover the edge a bit and it doesn’t budge but how,” a third TikToker commented.
“So the colors could be the reason why it seems to be moving. It’s like tricking your brain,” a fourth person tried to explain.
