Each of us at least once in our life thought about how animals see. And someone even dreamed of looking at the world around them through their eyes.

It is absolutely normal for a person to see the world in three dimensions and sometimes it is difficult for him to imagine how he can look at it differently. And animals see him in a completely different way, not in relief. In order to get a little closer to their feelings, conduct an experiment: close one eye and try to pour water into a glass. Most likely, it will not work the first time. Why is this happening? The answer is simple: by closing one eye, you are deprived of your usual worldview, the brain cannot determine the desired depth of the object. Your eye sees in one plane, exactly how the vision of a large number of animals is arranged.

There is a category of animals whose vision depends on the location of the eyes and on the natural conditions in which they live. For example, in a lizard, a pigeon, and a horse, the eyes are parallel to each other, on either side of the head. Therefore, they cannot see in three dimensions as a person. Closer to our vision can be attributed, for example, cats and monkeys, their eyes are located on the front of the head and the world for them is also embossed.

Let's turn to biology: each eye sees an object from a different angle, and the overall picture is formed by layering; to define this type of vision, the terms "binocular" or "stereoscopic" vision were coined. This is how the relief is created.

As mentioned above, the location of the eyes directly depends on the lifestyle and habitat of the animal. For example, a horse whose vision is not bold is able to see what is happening from the side or behind without turning his head. That is, in fact, she sees much more without changing her posture. This is due to her lifestyle, eating grass, there is no need for her to estimate the surrounding distance as accurately as possible.

How do predator animals see? The hunter needs to determine the distance to the victim with maximum accuracy in order to correctly calculate the jump. Therefore, his vision is binocular. Nature has laid down a greater number of herbivorous mammals than carnivorous ones, so binocular vision is quite rare in the animal world.

The keenest eyesight went to birds of prey, even though their eyes are parallel to each other. But there is a peculiarity here - their shape. Unlike animals, their eyeballs are slightly convex. Therefore, the bird sees absolutely everything that happens both from the front and from the side.

Scientists claim that most animals are color-blind, and a bee, for example, is able to see a color that the human eye cannot see. They do not distinguish between the colors of dogs, cats, raccoons, hares, ferrets and bulls, which destroys the myth that the latter is enraged by a red rag.

Lizards, turtles, monkeys and bears are well distinguished. There is an opinion that if an object is brightly colored, then any animal will distinguish it from others, it is not for nothing that nature has endowed many animals with a peculiar color.
