This one has been addressed a thousand times over. Right after Darwin says that in his book, he goes on for over three pages explaining how he thinks the eye evolved.
You can read it here:

But it doesn't really matter at this point what Darwin may have thought, given that we've learned so much more about evolution over the last 150 years than he ever could have dreamed. We have a pretty good idea of the steps involved in the evolution of the eye and we know that they are viable because they all exist in all kinds of organisms living today.
Sorry, totally inadequate like Darwin as a scientist.
Darwin felt the seemingly insurmountable problem of the evolution of what he called an organ of ‘extreme perfection and complication’ could be solved. From The Origin of Species:
"To suppose that the eye, with all its inimitable contrivance for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I freely confess, absurd in the highest possible degree."
So he tosses out hypotheses to point out how it could happen.
Complex things are stubborn facts.
However, the evidence shows that advanced vision appears almost at the very beginning of the fossil record. The oldest eye in the fossil record, a trilobite, is a very complex faceted compound eye that ‘dates’ back to the Cambrian period of about 540 million years ago.
The fossil evidence shows that from the beginning of the fossil record eyes are very complex, highly developed structures. We also have ‘living fossils’, animals that have remained virtually unchanged since very early in history. University of Salford biologist, Laurence R. Croft, wrote that the ‘precise origin of the vertebrate eye is still a mystery. The fascinating thing about the evolution of the eye is its apparent sudden appearance. Specifically, the fossils show that vision originated ‘in the early Cambrian’, which Darwinists put at ‘some 530 million years ago’.
Anyone have fossils of giraffes to show their long necks evolved?
