DID YOU KNOW?
An owl, that has one of the most powerful night vision in the Animal Kingdom doesn’t have eyeballs. Owls can’t move their eyeballs because they actually have none. Owl’s eyes are tube-shaped held rigidly in place by bones that are called sclerotic rings while a human eye socket with spherical eyes does not have sclerotic rings. 3% of an owl’s entire body weight is from its eyes while a human’s eye is accountable for only .0003% of body weight.
Despite having very large eyes, owls are actually very farsighted. According to National Geographic, their whisker-like bristles around their beaks help them detect close objects because they can’t focus on objects that are too close. Most owls are most active at night and have eyeshine that dramatically increases the available light on the owl’s photoreceptors giving it superior night vision. Aside from night vision, owls also have binocular vision or the ability of a two-eyed animal to see an object with both eyes simultaneously. Their field of view is 110°, and 64% of that is binocular. As for the protection of their eyes, owls have three eyelids. An upper eyelid that closes when the owl blinks, the lower eyelid that closes when it sleeps, and a translucent eyelid that moves horizontally across the eye.
