Most owls are nocturnal, meaning they are most active at night. Two adaptations help owls see well in the dark. 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.
Regarding this, what color do owls eyes glow?
Eyeshine and Night Vision Eyeshine color can appear, orange, yellow, green or blue, depending on the animal.

Their eyes glow because of a layer called the tapetum lucidum just behind the retina. It’s the lack of this layer that causes humans to have shining eyes only in photos, and not in flashlight beams. The relatively weak retina can only shine through during the powerful, and brief, flash of a camera.
What color are owls eyes at night?

Why can’t owls move their eyes?
Owls can’t move their eyeballs. That’s because owls don’t have eyeballs at all. Instead, their eyes are shaped like tubes, held rigidly in place by bones called sclerotic rings. Because owls can’t roll their eyes around the way we do, they have to move their entire head to get a good look around.
Why are owls eyes so big?
Owls have good night vision for a few reasons. First, they have a lot more rods and not as many cones, so they lose color vision, but see a lot better at night. Also their eyes are very large, so they pick up a lot of light rays. Owls have a sort of mirror at the back of their eye called the tapetum lucidum.
