I've heard that 'the eye can adjust' thing before, as you mention, when discussing field curvature. I've often wondered whether it is the eye that physically adjusts, or the brain? Does the cornea make microadjustments? Or does the brain just adjust its 'algorithm'? I fthe latter I would have thought feeding the brain more signal and less noise would still hold some advantages?
