Optical illusion shows if you have a dirty mind – but the truth is actually far more innocent

OPTICAL illusions have long been used to trick your mind – and this one may make you think naughty thoughts.

What you see first in this perfectly innocent image will show whether you have a dirty mind or not.

The cheeky optical illusion left users struggling to un-see the image.

The picture was shared online with the caption: "Is that good parenting?"

Viewers can easily spot a baby lying down on a bed as mum looks on.

But our eyes are instantly drawn to the left-hand side of the image because it's difficult at first to work out what it really shows.

If you look a little closer, you'll realise the optical illusion actually reveals a perfectly innocent family scene.

The dad, who is topless, is kissing the baby on the cheek.

There are several types of optical illusions – this image is considered to be a "cognitive" one.

It can be really difficult for our brains to interpret everything at once, so they will often take shortcuts.

Eye-care company  explained: "These illusions rely on what the subconscious mind thinks and how it relates one object to another." 

In this case, because of the positioning of the man's head, ears and his shoulders, our minds give us a simplified version of what we see.

Meanwhile, a bizarre image from a rock concert also left people wondering if they really do have a dirty mind.

The surprising optical illusion shows one blonde reveller putting on a very cheeky display - but all is not what it seems.

The image was shared on Reddit, with the title "big booty".

In another optical illusion, a festival reveller appears to put on a cheeky display.

Some reckon how you see the image could be a sign of a filthy mind - because there's an innocent explanation.

In front of the couple holding hands, your eye is drawn to the woman lying on her front on the grass - and viewers could hardly believe their eyes.
