Stunning optical illusion with "creepy" details

The last image to go viral on X, formerly known as Twitter, shows a black and white image of two young girls sitting next to each other in a park. Those with 20/20 vision may just see something else in the image.

Obviously, if you wear glasses or contact lenses, then by taking them off, you will be able to see something else. So, can you understand the optical illusion?

So, in the illusion, you have to look at the blonde from afar, without glasses and contact lenses. You should see how the child turns into the face of a creepy-looking old woman.

A woman's chin and mouth should appear where the top of the girl's head is, and a shadow on her neck and in her wavy hair will create two sunken eyes. It seems that this post has since confused people on the internet.
