The eye can detect a single photon of light ....you can not get any better than that .

Darwin persuaded much of the world that a modern eye evolved gradually from a simpler structure, but he did not even try to explain where his starting point-the relatively simple light-sensitive spot-came from. On the contrary, Darwin dismissed the question of the eye's ultimate origin… He had an excellent reason for declining the question: it was completely beyond nineteenth-century science. How the eye works-that is, what happens when a photon of light first hits the retina-simply could not be answered at that time.

Now that the black box of vision has been opened, it is no longer enough for an evolutionary explanation of that power to consider only the anatomical structures of whole eyes, as Darwin did in the nineteenth century (and as popularizers of evolution continue to do today). Each of the anatomical steps and structures that Darwin thought were so simple actually involves staggeringly complicated biochemical processes that cannot be papered over with rhetoric.
