Interesting!
Though: I can believe that our arrangement is a local optimum, sure. (Local in some genetic sense.)
That still doesn't make me believe that are anywhere close to a global optimum. Behold the octopus:
> Do these design problems [of optical blind spots] exist because it is impossible to construct an eye that is wired properly, so that the light-sensitive cells face the incoming image? Not at all. Many organisms have eyes in which the neural wiring is neatly tucked away behind the photoreceptor layer. The squid and the octopus, for example, have a lens-and-retina eye quite similar to our own, but their eyes are wired right-side out, with no light-scattering nerve cells or blood vessels in front of the photoreceptors, and no blind spot.
