Dawkins actually said 'obvious' not 'simple'. I can't see [sic] how aquiring a lens is 'simple' but I can see that it would be obviously useful.
But the 'obvious' point is that evolution doesn't care what's obvious, or even what's a necessity. All this anthropomorphical talk is confusing you - evolution deals with things that are good enough, Nautilus's eye is good enough to survive - by demonstration, had it not been, it would not be on our species list.
Evolution happens by a random process of mutation followed by a selection. Who knows how many, or if any, times a lens popped up in Nautilus's long ancestry - it needn't happen at all, and the anti-evolutionists say that it can't happen, - or it could have happened but there was no selection pressure for it, or animals carrying the trait just didn't survive.
The point is that evolution is not a certainty; in life's lottery there's no guarantee at all that any organisms will evolve anything, let alone the same things as other organisms. Its not possible for an organism to steal an organ from another - that's what a designer/creator would do, not what evolution can do. That's why we have hundreds of thousands of species not just one.
And that's real evidence for evolution and real evidence against creation. Thanks for the example.
