Article fails to mention: the eyes of the squid and octopus are very similar to ours in overall structure, but are not "wired backwards". So it seems that any explanation of why backwards is actually "vision-enhancing" is incomplete unless it also explains why it would not be enhancing for the squid. (though perhaps a justification could exist based on different wavelengths and lighting conditions underwater)

The vertebrate eye evolved under water as well (in fish).
