This does appear to be a fortuitous development. Now, I'm not a scientist, but... could evolution, say, find a way to get around the not-very-long-lived vision that is perhaps the limitation of the squid or octopus eye? That is to say, if humans happened to share an ancestor with the aforementioned cephalopods and inherited their "sensible" eye, would that have necessarily modified our evolutionary path to meet the constraints of said "sensible" eye, or could humans have evolved an even more suitable "sensible" eye to overcome the problem of not-very-long-lived vision?

Would an implication of humans having the "sensible" eye be that they would die earlier, or that they would go blind earlier? Or, perhaps, going blind earlier means they won't live as long... I guess one is tied to the other.
