A fair number of butterflies and moths have hindwing markings that resemble eyes.
It is thought that they may fool birds into thinking the butterfly is not appropriate prey.
I have no reason to doubt that, but I want to see what we're discussing before I comment on it. As I said, I can't very well comment on any thing unless I know what it is (and especially not if it's fictitious). BTW, 'eye markings' and "a bird's face" are two very different things.
I also wonder how they're supposed to fool birds. It's worth keeping in mind that birds have color vision and excellent depth perception, and so the types of camouflage that may fool, say, a lion or wolf would not fool a bird.
