How many times is the eyesight of a cat than a human, and the eyesight of a cat is not very bad

6 times

A cat can see things at night, and its eyes have a vision of about 100 to 130 degrees. Its monocular vision can reach about 280 degrees, which is six times that of a human.

Cats have a wide field of vision. Compared to its body, cats have the largest eyes of any mammal, and if the human eye were enlarged at this scale, it would have to face super large eyes up to 15 centimeters in diameter. The cat's eyes are positioned in a primate-like position, in front of the face, rather than on the sides of the head, as in many animals, giving the cat's eye good stereotactic ability to accurately determine the distance of its prey.

A cat's binocular field of view is similar to that of a human, about 100-130 degrees, but its monocular field of view is much better, reaching a maximum of 280 degrees. We humans cannot imagine such a wide field of view that is close to full angles. Moreover, the cat's eye is more sensitive to moving objects than the human eye, and it is these characteristics that allow cats to easily detect abnormal movements around them.

A talent for predators.

Cats need to have good eyesight to hunt, so eyesight is very good.

1. Flexible and changing pupils.

Their pupils can become smaller or larger depending on the light, mood, objects they are looking at, and so on. When the light is strong, the cat's pupils will shrink as thin as a needle, which is to prevent their retinas from being burned by strong light; And when the light is dim, their pupils will become as large as light bulbs, making it easier for cats to absorb more light sources.

And when the cat is frightened and feels scared, the pupils will also dilate; When the cat observes its prey and prepares to attack, its pupils will shrink again; The closer the object is to the cat's eyes, the smaller the pupils will be; The farther away, the more dilated the pupils become.

The cat's pupils can change very quickly, and they can be adjusted as needed as soon as they turn their heads.

2. The third layer of the eyelid - the transient membrane.

Cats have their third eyelid hidden in their eyes, and the transient membrane can help cats clean and protect their eyes. Because the film is in the cat's eyes, the owners should not touch it for curiosity, it will accidentally cause the cat's eyes to become inflamed, and the cat's eyes are also very fragile and sensitive.

3. The "reflector" in the cat's eye - choroid.

There is also a thin film in the cat's eyeball that helps the cat reflect light under the retina, which is why the cat's eyes glow at night. The light source is collected through the pupil into the retina, and then reflected back to the retina through this reflector, so that when the light is dim, the secondary use of light increases the cat's night vision ability.

2. What is the world like through the eyes of a cat.

The cat's field of vision is divided into all and two eyes, all of which are used to observe the prey's every move when hunting, and the two eyes can visually measure the distance from the prey, and can also notice the environmental changes on both sides.

Relevant experts have done a comparison of the world in the eyes of cats and humans, and found that the overall field of vision of cats is wider than that of humans, which can reach 200 degrees, but their eyesight is very poor, for distant objects, they can only see a vague approximate shape, but they are very sensitive to moving objects, as long as the object moves, they will respond immediately.

Cats have good night vision, which is mainly related to the special structure of the cat's eyes. In addition, in order to maintain night vision, cats need to supplement with adequate taurine every day, and if they do not supplement enough taurine for a long time, it may lead to decreased vision in cats. Generally, pet cat food will add a certain amount of taurine to meet the needs of cats.

In addition, you can also purchase special taurine health supplements.
