McDonald's just released an optical illusion that's ruining everyone's eyes

Fast food chain McDonald's recently posted an optical illusion to its Facebook page and it giving us a bit of a headache.

The message itself is very hidden (apparently you need to move away from your screen a bit).

Picture: McDonald's 

For the special few who have vision good enough to read between the lines, the message apparently reads "Bring McNuggets".

Fortunately, someone decided to give the rest of us a helping hand...

Either way, all this straining of the eyes is making us hungry.

Did you see the message?
