Animals: the incredible way they see the world


Animals see the world differently than we humans see it. Have you ever wondered how the dog, the cat or even the flies see the world? Because each species sees colors, textures, and light differently because of the way the eye system has evolved, there are a lot of types of vision that humans have never experienced.

  1. Dogs

For a long time it was thought that the world of dogs was monochrome, they could distinguish objects only on the basis of differences in light and contrast.

It is now known that these animals have a dichromatic view in shades of yellow and blue. The dogs have a very good sight and behind the eyes there is a reflective layer called “TAPETUM”. This wallpaper helps to amplify the perception of light in poor conditions. The central part of the retina has 20% cone cells (and we humans have 100%), which makes their daytime vision much less detailed than ours.

  1. Horses

Horses have eyes on the sides of the head and have a much larger field of view than ours. However, horses cannot see up close, directly in front and have a triangular blind area that extends up to 1.2 m in front of them. At greater distances, horses can use both eyes for binocular vision, but horses can also use each eye separately.

eg: with one eye facing forward and one facing back, even so, they can prevent dangers.

As with most mammals, the world of these animals is a combination of shades of yellow, green, blue and gray, they cannot see the color red. That is why it is very important when approaching a horse not to do it suddenly because the horse can be scared and hurt you.

  1. Cats

The sight of the cat, as in dogs, is able to distinguish shades of brown, blue and yellow. These domestic cats have a much wider field of view than humans, about 200 degrees (compared to 180). What is most interesting is that cats have an inner fleece for extra protection.

  1. Birds

The birds were endowed by nature with a very good look. Nocturnal birds feel great in the absence of light, and during the day they can differentiate colors that humans cannot. Also, their eyes perceive the world in ultraviolet.

  1. Flies

The two big eyes of flies are compound, ie made up of thousands of lenses that contribute to the integrated image that flies see. To understand what compound eyes mean, imagine several thousand cat eyes together, which together form a complete picture. Also, flies fly you in the ultraviolet, and the world around them is slower than for humans.

  1. Cows

For these animals, the plains on which they spend most of their lives are not green, but rather in shades of orange and red. They also see a larger picture of the objects around them.

  1. Snakes

Snakes have bad eyesight, but at night their situation improves significantly, because their eyes perceive thermal radiation ten times better than any infrared technology. However, during the day they only notice the movement, because of this they cannot see their prey if it stands still.

  1. Bees

For bees, the world is three times faster than for humans. They also see in ultraviolet, which is impossible for humans.

  1. Rats

First of all, did you know that rats can expand their field of vision in a way that we humans cannot? These animals are able to move each eye independently in different directions. This is a naturally evolving process that allows them to better avoid potential predators. Unlike us, these scrapers cannot distinguish colors, but they recognize strong light very well.

  1. Sharks

Underwater predators, such as sharks, do not distinguish any color, but their underwater vision is much more developed than that of humans.

  1. Chameleons

In addition to the very interesting appearance, chameleons also have some amazing eyes, which can move independently of each other. This allows chameleons to see 360 ​​degrees.
