So often, to see an optical illusion, you either need perfect vision or you have to look at a photo in just the right way, but now there is a tricky image that can only be seen if your vision isn't ideal.
At first glance, it just looks like a black and white photo of two girls hanging out at a park. If you have 20/20 vision, that's all you see. However, those of us with less-than-perfect eyesight can spot something else. If you wear glasses, take them off, and if you have contacts or good vision, squint, and then you will see a face appear on the torso and head of the blonde girl. The figure's chin and mouth show up on the girl's shirt, while her neck and hair make up the face's eyes.
Commenters were taken aback by the illusion. One wrote, "Freaked me out!" and another stated, "Thanks, I hate it." Meanwhile, those with superior vision have been left wondering what's in the illusion, with one asking, "For those of us with eagle eyes, what are you mole people seeing?"
A blurry version of the photo was shared to help those who couldn't see it.
