Eye doctors will often tell you that squinting is a bad thing for you, but you need to ignore that for the sake of the optical illusion sent out via Twitter by late-night host James Corden.

The man has a frown on his face. However, when you look at the image with half open eyes, the image appears transformed, replaced by the face of a young woman... and she's smiling. CREEPY... and COOL! [Daily Mail]
