McDonald's optical illusion is messing with people's eyes

Good ol' Macca's is at it's crazy persuasive (like we need persuading) advertising again, and this time, it's an optical illusion with a special hidden message...that no one can see.

Take a look! The key is to read between the lines...

Can't see it? Make like Omarion and put some distance between you and the image.

If you're like the rest of us, the post just looks like lines, and now your eyes are sore. If you can see through the illusion, you'll know that the message says "Bring McNuggets."

This is an edited version of what the post looks like to someone with the magic ability to see the hidden message.

Who'da thought we had such sensitive eyes...anyone up for some nuggs?
