An optical illusion on July 4th has confused views a bit and sparked debate among social media users.
The illusion shared months ago on Reddit by user FoxyJnr987 is simply an American flag.
However, there seems to be something unusual about the flag, as the vertical lines appear to be slanted.
In addition, the red and white boxes that make up the flag’s stripes are scattered enough to confuse one’s eye.
Reddit user FoxyJnr987 captioned the thread, “United States flag but it’s this weird optical illusion.”
The Redditor simply shared the illusion, a digital image of the American flag, but offered no further details until another user asked, “What is the illusion.”
FoxyJnr987 then explained that the flag photo was a “cafe wall illusion”.
“I rotated it to look like stripes and made the black squares red instead,” said FoxyJnr987.
“The gray lines that run vertically look slanted when they are actually straight. It looks better horizontally.”
According to Brain Connection, a cafe wall illusion teases the brain into believing that the lines in the image aren’t parallel, when in fact they are.
“It is believed that the café wall illusion works because of the high contrast in the two different ‘bricks’.
“When interpreting images, our brain tends to ‘distribute’ dark zones into light zones, a feature known as irradiation is ‘movement,’ which is likely to cause a false distortion effect.”
Meanwhile, other users have not seen anything wrong with the image.
One person commented: “All lines in the flag are straight, they are not diagonal.”
“Thank you for making my eyesight worse,” wrote another.
A third user wrote: “You don’t look weird to me, is my brain broken?”
