A clever optical illusion means it’s impossible to see all the dots at once.
Although there are actually 12 dots, the image has confused millions of people, 1.9 million to be exact.

Did you find them all?
Can you see them now?
However, this image is nothing compared to the simple dress that managed to divide the internet.
Blue and black or white and gold?
Twitter users went wild when a woman posted a photo of this dress online.
Friends, family and colleagues divided into two camps, those who thought the dress was black and blue and those who saw it as white and gold.
But what color is the dress?

For anyone who has seen the blue and black dress, you were right.
The reason for the controversy lies in the way people see colors.
Our perception of different colors depends on the shades that border each other, and conflicts send unusual signals to our brains.
Floating head
This bizarre image of what appears to be a floating head has Reddit users confused.
In the photo, a woman with braided blonde hair and long legs can be seen drinking a cocktail, but her body has mysteriously disappeared.

Reddit user High On Tacos explained the reason for the optical illusion: “Refraction. When light leaves/enters the water, it bends and travels in a different direction than your eye.
“What you see from this low camera angle is what you would see from a much steeper camera angle, if there were no water.”
Beard or glasses?
In August, this perplexing optical illusion went viral once again.
People just couldn’t understand what was happening in the photo.

In reality, the recording was, as the title says, a photograph of a man: “looking up with his chin up.”

The provocative photo was originally shared on Playbuzz, before it went viral and confounded the rest of the internet.

This optical illusion is known as Troxler’s vanishing, which was discovered by a Swiss physician in 1804.
If you see a black dot or a cross, the colors disappear after about 30 seconds.
Paul Troxler discovered that the brain stops paying attention to visual scenes that don’t change.
