That is a creationist red herring. If you learn about evolution, you will learn why your question doesn't make sense.

Yes, if you ignore everything we know about the biology of the eye, biochemistry, DNA, and evolution, someone can come up with an imaginary story about how an eye might have developed from an eyespot.
But if you look at the mathematics behind causing even one gene to change, you see that the idea that a whole eye could evolve into an eyespot undirectedly is absurd.
