Most of us are probably familiar with the topic of this article, zombies. But are you familiar with their vision? Yes zombies are not as sharp eyed as most creatures, but the real puzzle is: why? One explanation is that they are unable to properly focus & open their eyes due to the loss of muscle control brought on in the infected. Another is that when a human transforms into a zombie their irises are mutated by the infection leaving the zombie partially blind. Although zombies can’t see very well, they have an advantage at night when vision is not as large an advantage for humans. This explains why zombies prefer to come out at night rather than the day. In any case a zombie’s eyes are not it’s most useful attribute, but their teeth . . . that’s another story.
