It looks like the video recaps explanations Stephen Jay Gould put in print a while back. An incremental thing, starting with Euglena's eyespot, moving up to the cuplike eyewell in flatworms, then with protective clear window over it, the window which will evolve to become a cornea/lens system.
We should realize, however, that flatworms did not evolve from Euglena. They had to use an all-modern creature lineup because most of the putative intermediate steps in eye evolution aren't represented in the fossil record. Another item of note is that camera eyes as complex as any modern examples may have appeared back in the Cambrian, right after the beginning of animal life itself. Of course that still accommodates five million years to evolve the eye, but it happened very fast compared to the five hundred million years of essentially no change in eyes since then.
Preferable to creation myths in terms of realism and supporting data, nonetheless popular accounting for evolution glosses over a lot of difficulties.
Odd that you'd reference one of the authors of punctuated equilibrium without bringing his own explanation to bear on the issue at hand.
