Animals and some amazing facts about their eyes (PART II)

While humans have adapted to eye issues through the use of spectacles and eye care, we were not the only ones who have succeeded in inventing innovative ways to circumvent natural selection. Nature is full of fascinating species who thrived in their environments because of some type of visual skill. However, for every species that has thrived due to their eyesight, there are countless that have failed due to a lack of vision.


Dolphins sleep in a completely different way than humans do since they must still surface to breathe. Humans experience extensive periods of unconscious sleeping and are unaware of their surroundings for extended periods of time when sleeping. Humans have a respiratory reflex, and we continue to breathe mechanically whether we sleep or fall asleep. To prevent being eaten by sharks, dolphins and whales frequently sleep with one eye open. The capacity to remain partially cognizant also helps them to breathe while sleeping. 

The dolphin will shut off half of its brain, as well as the matching eye. When the left half of the brain is closed, for example, the left eye shuts. Another advantage of this type of sleep is that the dolphin may continue physiological processes, such as muscular activity, that aid the warm-blooded mammal in maintaining body heat necessary to survive in the cold water.


Owls are fascinating birds that quickly attract the sense of curiosity of birders. These facts may assist to break up some of the mysteries surrounding owls and demonstrate what a hoot they truly are.

Owls have "eye tubes" that extend far back into their skull instead of spherical eyeballs, which means their eyes are locked in place and they must tilt their heads to see. Humans, on the other hand, have a 180-degree field of vision, with 140 degrees being binocular. Because its eyes are on the side of its head, owls possess an incredible 360-degree field of vision. However, only around ten degrees of this is binocular.

Their large eyes let them to see in the dark, and they are far-sighted, allowing them to identify prey from meters away. Everything appears blurred up close, and they rely on tiny, hair-like feathers on their beaks and feet to detect food.


Camels have a distinct appearance and are easily identified by their humps. They are found throughout Africa and Asia's deserts.

Camels have three lids on their eyes. Two of the eyelids contain lashes that shield their eyes from sand. The third is a very thin lid that acts as a "windshield wiper" to clean their eyes. It shuts and opens from one side to the other rather than up and down. It's also thin enough that the camels can see through it. So, if there is a sandstorm or a windy day where sand is being stirred up, they may close that lid to shield their eyes from the sand while still seeing where they are going.

Animals have a variety of secret techniques for living in the wild. In special circumstances, the animal's eyes may be used as a weapon. Some creatures of the animal kingdom are terrified of blood in the same manner that some people are.

Nature is a good reminder of how vital our eyes are and why we must care for them. In nature, having a better pair of eyes can provide a competitive edge that could really assist us thrive.
