The owl's eyes are so large that they can't turn in their orbits, so much so that they can only turn their heads like the horror scenes in the movie The Exorcist. It all starts with a complex system. Compared to other animals, the blood vessels in the neck of the owl are thicker and become thicker when they enter the head.
