Do owls have eyeshine?

Finally, owls have “eyeshine.” Eyeshine is a result of an animal’s tapetum lucidum—a layer of tissue behind the retina that reflects visible light. This reflection dramatically increases the light available to the animal’s photoreceptors, and gives it superior night vision. Like many animals, owls have three eyelids.

How do Owls see in the dark?

Two adaptations help owls see well in the dark. First, owl eyes are dominated by densely packed retinal rod s. All animal eyes have photoreceptor s shaped like cones and rods. Retinal cone s function best in bright light and are responsible for color vision.
