Are The Lines Straight Or Curved? This Mind-Blowing Illusion Has Left the Internet Confused

Optical illusions are one of the most fascinating and mind-boggling things to witness! They are fun and inspire a creative mind, making you think out of the box! Recently, an optical illusion has gone viral and it’s confusing everyone!

An optical illusion is an illusion caused by the visual system. It is characterized by visually perceived images that differ from the objective reality. They are one of the most mind-boggling images because they literally trick your eyes! Today you see many optical illusions on the internet, but this one specific illusion has thousands of people stumped! It’s called the Cafe Wall Illusion and it was created by a woman named Victoria Skye.

In the image you can see that it appears as if the lines bend at a certain angle and curve – yet, the lines are actually completely straight and parallel! You might be positive that at least four of the lines are curved, but you’d be wrong! Take a closer look and you’ll see that they’re straight! According to Wolfram MathWorld, the illusion was first spotted back in 1979 on the wall of a café in Bristol, UK. Since then, it’s been modified in various forms to create the same trick, confusing minds around the world ever since.

“The scientists say that the reason the illusion exists has to do with how the white and black edges interact in opposite directions along the straight edge, tricking the brain into thinking there is a slant in the line,” Skye stated.

“That’s why, if you blur the image, the effect disappears… because you cannot resolve the tiny white-black interactions once they are blurred, so the brain is no longer led down the garden path.”
