    So many animals have yellow eyes. Why do they?

    Brown, blue, green. We humans share those eye colors with our animal friends. But what gives animals that extra yellow?

    Animals that have a reflective layer in the retina called the tapetum have eyes that seem to glow but, in fact, only reflect light that shines on them.

    Actually it is a luminous layer on the outside of animals eyes that humans don't have. This layer actually helps with seeing in the dark by absorbing the vision of light. Unfortunately, there vision is not as good during the day as ours. If we had this layer we would not be able to read fine print.
