Evolution of the Eye

Could someone explain to me how an eye evolved with such complex network of enzymes and such?

I guess I am looking for how the interactions between rods and cones and all the other specialized cells could have evolved.Rrhain, I have seen that website before, and showed it to this creationist and he didn't accept it.Thanks for everyone's help otherwise.

Ok, here is what the guy said that he's looking for(and his response to Rrhain's website)"Ive seen this website before, but all it says is how you could evolve the apparatus, it doesnt say how you could evolve all the complex reactions and molecular changes, etc. Evolution cannnot support the evolution of the eye when you look at all the extremely complicated processes involved. All the rod and cone cells, with all the reactions invovling vitamin A, alcohol and many other proteins, you cannot say it evolved through random mutation and natural selection. Its impossible, Darwin accepted the fact that it couldn't be done, and it has yet to be proved by modern evolutionists."So I guess I'm looking for how the interactions between cells could have evolved.
