What the world looks like through the eyes of a cat
It is strange, of course, how one can understand how animals can see the world. Physically, we can assume how the vision system works for them, but we cannot receive confirmation.
Under the cut composition, which made the artist Nickolay Lamm (Nickolay Lamm). Like he would show us the world how cats see it. He consulted with animal clinics experts, Dr. Hausler from the Animal Eye Institute and with leading ophthalmologists before publishing these photos.
Oh, there are still big doubts about the authenticity of all this ...
The panorama of the city is blurred, as the cat cannot clearly distinguish objects that are more than six meters apart.
At the top of the photo on the sides there are black rectangles showing areas that the human eye does not see. In cats, the field of view is wider, so there are no black rectangles on the bottom photo.
If the cat had flown over San Francisco, she would have seen him in a daze.
Cats do not see the world as bright because of a different set of receptors on the retina.

But at night, cats have an advantage over man.In the dark, they see much better.
Many believe that cats see in the dark, like during the day. This is a common misconception. In fact, cats see little better in the dark than people (because they have eyes, not headlights).
Since ancient times, our Murks have got used to hunting in the dark, and this is precisely what explains this unusual structure of the eye. The eyeball of the "cat" lies deep in the eye socket, and in order to better examine the object located in the peripheral area, the cat has to constantly twist its head.
No wonder they talk about a person who is well-versed in the dark - sees "like a cat." The eyes of a cat are distinguished by their supersensitivity and can cover a viewing area of 270º. And if you also take into account that the animal is very nimble with constantly turning head, then it turns out that the cat has a full circular view.
Cats are far-sighted animals! This is due to the characteristic feature of the structure of their lens. If cats could read, then they would have to keep the newspaper at a distance of 2 times more than us, that is, not 30-40 cm, but as much as 80cm. But further than 8-10 meters, the cats again see badly. The cat's eyes are directed forward and their visual fields overlap - thisprovides stereoscopic vision.
Due to the specific structure of DNA in the cells of the retina, the cat sees well even at night. In the eye (and the human eye as well) there are two types of supersensitive cells - cones and rods. Cones provide accurate and clear vision, helping to see all the colors of the world, and the sticks are responsible for twilight vision. In our eye, the wands are scattered across the retina, and the closer they are to each other, the better the person sees. In the cat - sticks are deployed so that the cells form microlenses. Cats catch even a weak light: at dusk, cats see 10 times better than we do. The rays do not scatter, but concentrate in one direction.
In addition, the wands help to follow a very fast movement, so the cat can easily keep track of, for example, the movement of a point from a laser pointer, although at the same time a person is 10 times better in seeing slow moving objects.
In addition, the pupil of a cat is able to expand in low light and increase in diameter up to 1 cm, which allows you to capture the maximum amount of light. And the ability of a cat's pupil to narrow to a narrow vertical slot is a remarkably effective way to reduce luminous flux. When you see a cat squinting, know that it is not from bright light, but from pleasure.
In the cat's eye there is a specific mirror layer, which is located behind the retina of the eye. Even the faint rays of light are reflected from it. It is because of him that the cat's eyes glow in the dark! And this layer also works as an amplifier of light perception: thanks to it, the retinal sticks receive a charge of irritation.
And finally, cats see us better in the dark, as they distinguish up to 25 shades of gray. But in the light of the details we are worse. And they do not care what color food! It is believed that the red color of the cat does not see at all.
