When it comes to an optical illusion, it's either confusing or fairly simple.
But sometimes what you see might appear differently to others around you.
So do you think you know what's going on here?
The image shared on Bright Side shows a circle which consists of blue, white, green and black shapes.
And the more you look at it, you'll think it's definitely moving.
After a while you might even start to find that it's making you feel dizzy.
Luckily there is some sort of an explanation to this brainteaser.

The truth is, these circles aren't moving as they're actually motionless.
An illusion like this occurs because of the cognitive effects of interacting colour contrasts, object shapes and position.
So you might think an optical illusion with a static image is moving, but it's not true.

Previously, a mind-bending optical illusion was shared and it'll leave you baffled.
It was shared on Optics4Kids and shows black, blue, green and white colours on a background.
The image looks as though it is forming a pinwheel sort of shape.
According to the website, the pinwheels aren't actually moving.
On another occasion, a mind-bending grid optical illusion asked users to "count all the black dots".
The image was an example of a Hermann Grid Illusion which occurs by "ghostlike" grey blobs on a black background.
We've seen it happen in this Apple Mac keyboard optical illusion which left Reddit users baffled.
When it was shared, one said: "Yeah I would never be able to concentrate."
