Today I’m writing about animals that can see in the dark. The animals that can see in the dark are nocturnal animals. How do animals see in the dark? The light from the moon goes to the animal’s pupil to the optic nerve to the brain. That makes their eyes glow. There’s a type of tape in back of the eye which makes it glow. It’s tape you put on bicycles so people can see it in the dark. What you want is called "retro reflective tape" -- it reflects light back the same direction regardless the angle of incidence.
