We may also question a zombie's use of eyeglasses. If a living person needs eyeglasses to see, doesn't the same logic apply to a zombie? Perhaps all the zombies shambling about only need eyeglasses to improve their vision and would not be so clumsy while pursuing their prey.

One possibility is that zombies don't see the same way that humans do. Rather, they use their eyes to "see" the heat from living bodies and then head in that general direction. That, combined with smell, would make it very difficult for living humans to hide among zombies since zombies have far less body heat than living humans.
