A cat is considered a close friend of a person alreadymore than 10 thousand years, but, despite this, it remains a mysterious animal, with which we still have to get acquainted closer. Today, the cat family is credited with many unique abilities, for example, to see in the dark and feel otherworldly beings. Let's see what kind of sight the cat has, can it, for example, see in the dark.
Many wonder why cats seedarkness. But is it? Of course, a cat at night sees better than a man, but it can not see in pitch darkness. This is due to the fact that in this species of animals the pupils are narrowed, and they need much less light particles to clearly see the objects. In the process of evolution, this ability developed for a quality ambush at any time of the day. Despite the fact that vision in the dark in a cat is eight times more effective than a human, in pitch darkness it is still incapable of seeing. The world through the eyes of a cat is not the same as a person's, because of the perception of colors, let's look at why.
Due to observations of scientists it was found thatthe eyes of a cat are seen in the same way as human ones, but they have slightly greater possibilities. Experts call cat eyes binocular. With this type of high myopia, which allows you to perceive the world in three-dimensional form and allocate all objects in the field of visibility, but the farsightedness of the binocular view is much less than the human.
Due to its shortsightedness, the cat clearlysee objects located next to it, but because of the pathologies of the eyes they see only certain colors. Many people think: do cats have color or black and white vision? Let's figure it out.
Some animals see the world in black and whitepicture. But not cats. They very clearly perceive the blue and green color in the surrounding world, but at the same time red, brown, orange and purple almost do not see. Evolution has made such changes in the sight of felines because of their active nightlife, which led to the development of only certain areas of the brain.
A person discerns a huge number of colors bycompared with a cat. She, of course, sees the world not in black and white colors, but the blue-green world is also not saturated with a large number of shades. Therefore, we can assume that the cat sees worse than her best friend. In addition, she can not see what is happening at a long distance, unlike other animals. Therefore, the world through the eyes of a cat is quite different than that of other animals. But why does a person distinguish between objects and see better quality for long distances?
A cat is a nocturnal carnivorous animal, soit is very important that her view of the night time allows you to distinguish between prey among unnecessary objects. In the dark, a cat, just like a human, can not see the color, it is associated with light particles, which are very few at night, but it sees more distinct animals. But the world does not become yellow, green and blue, but gray.
At night, the cat can distinctly distinguish between graya shade, which, of course, affected the choice of the favorite prey of a homemade prankster mouse. But what kind of sight the cat has, it in any case stands out clearly against the background of other animals.
Of course, the whole thing is in the brain. Unlike humans, cats have developed areas of the brain that are responsible for hearing and sense of smell, so the sight of felines is worse than these feelings. In humans, most of the neurons take away the motor skills of the hands.
Unlike other creatures in a cat, vision isan auxiliary feeling, and not the main one - hearing and sense of smell are the main ones. Evolution has put everything in its place due to the fact that the cat is considered an animal hunted from an ambush. That's why she does not need a farsighted view for several kilometers.
Dogs see better than cats, and it's connectedalso with the development of the brain. The structure of the limbs and their work in the family of felines is much more complicated, therefore, in conjunction with the development of sites responsible for hearing and smell, there is no room for vision on the surface of the cortex of the brain in cats and they see worse.
Many believe that every cat with green eyes, is it so? In fact, today, cats have a lot of eye shades. Here are the basic colors:
It can also be a cat with green eyes, but it is often associated not with the breed, but with the fact that the color gradually fades or is visible only in a certain condition of the pet.
Let's sum up what kind of sight the cat has. Despite the fact that the structure of the eyeball is similar to the human, the cones and rods in the cat family are much more sensitive. They do not need a large amount of light, so they react to any movement even in the dark. To the peculiarities of the sight of cats is the fact that they do not see the object in the smallest details, but only its silhouette. But any predator who leads an ambush hunting is enough to catch prey.
To understand what the cat's vision is in the daytimethe time of day, you should know that in bright light its pupils narrow, in order to regulate the flux of light particles. Because of this, in daylight, the eyes of the cat are seen a little worse than in the evening. But it is able to see with its own eyes infrared radiation, which is inherent in all living beings.
The peculiarities of binocular vision includewide coverage of the surrounding world, but this type of vision is developed in cats. They see, unlike other animals, 270 degrees around, it is much wider than that of a person. But in connection with this, the feline fixes the vertical movement worse, but they see the horizontal movements of the prey perfectly. Probably, this is due to the fact that they rarely catch flying animals.
At night, cats are seen better than during the day, due to the fact that their photosensitivity is too strong. It is connected with this and the fact that cats like to sleep in the daytime, and at night they hunt.
