This study shows that nonvisual mechanism(s) can guide chick eyes to recover from myopia or hyperopia bidirectionally to regain their age-matched length. Because eye growth control is phylogenetically conserved across many species, it is possible that, in general, emmetropization mechanisms are not exclusively based on a local visual feedback system.
