Only people with sharp eyes can solve 'irritating' optical illusion in seconds

It's not always easy having to switch your sharp vision on and trying to work out what's happening in an optical illusion. Recently, people were struggling to spot the hidden image, while only those with good eyes could understand another brainteaser.

Now with the latest puzzle, you'll need a lot of patience and a good set of goggles on you. So are you ready to conquer it? In a post on Reddit, a forum designed for optical illusions shared a standard grid but you'll have to be very clued up to understand what is actually happening in it. The picture's caption read: "All of these lines are straight."

While it might seem straightforward once you've read the caption, take a look at the picture and you'll find it's actually more disorientating than you think.

It shows a grey grid with green lines all over, some of which are straight and others appearing to be bent. But that's where you're wrong...

So why is this optical illusion really confusing?

When lines appear bent but are straight it could mean it's an example of the Cafe Wall Illusion or the Hering Illusion. This is caused by brain processes that interpret surrounding patterns or backgrounds.

These illusions can occur because your brain is trying to make sense of the visual information by using past experiences and context, which leads to misinterpretations.

What is the Cafe Wall Illusion? This might be alternating rows of dark and light blocks which make parallel straight lines that appear curved or bent.

And how do you know it's a Hering Illusion? This is when straight, parallel lines can seem to bow outwards when seen against a background of radiating lines.

Whatever optical illusion it might be, it's certainly left people scratching their heads on the Reddit post. And since it was shared, it racked up hundreds of upvotes as one commented: "This is genuinely irritating. Well done."

While another added: "I hate it here." A third posted: "Liar." And a fourth chimed in: "No they're not! I refuse to accept that."
