Many cat owners probably dream at least for a day to find themselves in the shoes of their pet, to look at the world through his eyes. Although the organs of vision of cats are very similar in structure to the human ones, in the process of evolution, the eyes of cats adapted to specific conditions, so the cat's vision has its own specifics. Representatives of the cat family learned to perfectly navigate in low light conditions and sensitively respond to the slightest movement, but for this they had to sacrifice the subtleties of color perception and some other features.
The artist and researcher Nikolai Lamm managed to create a reliable model that gives an opportunity to imagine how cats see the surrounding reality. After consulting with experts from the School of Veterinary Medicine at the University of Pennsylvania, Lamm developed several visualizations that allow you to compare the vision of a cat and a person.

When creating this model, Nikolai took into account various factors: for example, the width of the peripheral vision - in cats it is 30 on each side, and the person can only boast 20, thus, the total visual width in cats is 200 (in humans 180). But we see much further - a person is able to clearly distinguish objects at a distance of about 30 meters, while it is difficult for a cat to examine an object if it is farther than seven meters from it.
Also, the cat's eye perceives poorly brown, red and orange colors, but sees blue and yellow perfectly. Due to the greater number of special photo-receptors in the eyes of the cat they see in the darkness 6-8 times better than a man - this ability allows wild members of the cat family to hunt at night. By the way, the cat's eyes have an interesting feature that many probably noticed: in the dark they emit an unusual phosphorescent glow, this is due to the presence of a light-reflecting pigment in the tapetum - a layer of tissue behind the retina.
No. 1. They distinguish colors!
You will be surprised, but cats are able to see some shades of colors, although for a long time there was a theory that katofey distinguishes only black and white. Of course, there is no need to talk about a wide color spectrum, but still the purr can be distinguished by blue from yellow.
If we compare his ability to see colors, then to some extent it resembles a color blind, whose eyes also do not perceive very well all the richness of existing tones.
No. 2. Blue eyes are not a sign of deafness.
Many people are convinced that cats with a celestial iris are unable to hear sounds, but this is not so. Often, deafness can speak not only the blue tint of the visual organ, but also the pet's fur, which is white.
But this is not always true! Many cats perfectly hear, despite the light color of wool and angel eyes.
Scientists believe that a high probability of detecting a cat without a hearing also occurs with other genetic features. So, if your white-haired Marquis or Murka have blue eyes, do not rush to write down your pet as deaf.
Number 3. Bright shades do not interfere with the cat!
Some people think that kotofeya can be irritated by too saturated colors, causing aggression in it or simply acting on the optic nerve in a negative way.
In fact, this is not true - the cat, and especially the one that focuses on prey, is completely indifferent to any bright tones.
Simply put, not a single saturated color will distract her from the goal, no matter how hard you try!
# 4. Perfect vision in the dark? No matter how wrong!
There is a common opinion that cats have keen eyesight, which allows them to see in the dark very well. Recent studies have proven this to be misleading.

No. 5. The cat's pupil reacts faster to light than the human.
We all know that with the penetration of bright light into the eyes, our pupil immediately expands. The cat is about the same story, but everything happens much faster!
In addition, her pupils are more sensitive to the difference in light, so they expand and contract much more actively, and with the slightest change or weakening of the beam.
Changing the cat's pupils may indicate other factors - excitement, fear, aggression, so if your purr looks at you with wide eyes, think about it - maybe something gives him discomfort.
№ 6. The cat does not see objects close to him.
If you have ever given a cat food in a bowl, you probably noticed that the animal poked awkwardly with its muzzle before understanding what was happening.
Incredibly, but a fact: the purr sees it perfectly from a distance, but it is very difficult for her to focus her eyesight on objects located right under her nose.
Speaking easier, if your cat thought up to read a book, you would have to urgently get him glasses for myopia!
№ 7. The angle of view of cats is wider than in humans.
Our eye is able to catch everything that is done within 180 degrees. In the striped - tailed situation is much more profitable: its angle of view is more than 220 degrees!
Nature endowed the cat with such an ability not by chance, because he was conceived as a predator, not a sofa creature.
It is a broad overview that allows the kotofey to hunt well and find prey, deftly calculating the distances from him to himself.
Well, and finally, a mystical fact about cats, which proves that these creatures see the world differently, because they have an increased sensitivity.
They are able to predict accidents, they feel fine when the owner is ill, and they understand everything at a glance of their huge eyes!

1. Despite the common myth cats see the world not black and white. However, their perception of color is different from human.
2. Cats poorly distinguish small details. The structure of the cat's eyes is arranged in such a way that it sees the leaves on the trees or the text in the book is much worse than you and me.
3. Cats can be color blind. Oddly enough, the mechanism of color blindness in cats is the same as in humans: they do not distinguish red from green.
4. All kittens are born with blue eyes. Over time, this color changes (or not, because in some breeds, for example, in Siamese cats or ohoz azules, the eyes remain blue).
5. The cat's eye is additionally protected by the third century. This eyelid can be especially clearly seen when the cat is very pleased or sick.
6. The vertical structure of the cat's pupils allows them to narrow and expand much more than the pupils of a person do. This is what allows cats to see well at night. During the day, the dilated pupil may indicate that the cat is extremely excited (for example, during a game) or severely frightened.
7. Cats kiss eyes. If the cat stares at you and then blinks slowly, this is a sign of deep affection.
8. In honor of the cat's eyes are named:
Ornamental stone
Nebula in the constellation of the Dragon
Fashionable glasses style in the 1950s and 1960s
Comic character marvel
