The whole “dogs are color blind” myth was disproved quite a while ago, and now science shows that chickens and other birds may have better color vision than people do. It may be due to evolution – as birds evolved, they spent more time in sunlight than most mammals did – but chickens (and other birds) have better organization of the receptors in their eyes that detect color. Learning more about chicken eyes could help researchers find treatments and cures for many eye diseases that can cause blindness.
