Cats can be seen at night, can move normally, and walk freely. Because a cat's eyes are better at collecting light than a human, even a faint light can make it see clearly. And cats also have whiskers, whiskers are mainly tools to measure distance and direction, when the eyes and whiskers match, cats can be at night as during the day.
In a pitch black environment, there is not much difference between the vision of cats and us humans, because there is no light and cannot be reflected. But when there is light, even if it is only very faint, the cat's eye can collect and process every ray of light available to fit into the darkest places and see things clearly.
In terms of organ proportions, the retina of a cat's eye is not larger than that of a human, but compared to the human eye, they can collect and absorb effective light in an unusual way. The reason for this is that cats have much larger corneas, pupils, and lenses than humans. Therefore, the lens and cornea are positioned relatively close to the retina to allow the light to be precisely focused and increase the curvature of the two.
Another advantage of this structure is that cats' eyeballs are shorter and more round than humans, giving them a wider vision than human eyes.
Humans do not possess the skills to receive and preserve light in the eyes of cats and other animals, known as bright carpets. Located behind the retina, this reflex structure is made up of up to fifteen layers of special cells that shine like a high-performance mirror.
Cat owners know that cat's eyes are capable of emitting a characteristic light in the dark, whether green or red or gold. This is because the cat's pupils are wide open, and the light can be reflected from the blanket, which is why this effect is produced.

Cats can see at night, and cats' night vision is very strong, because cats' eyes can gather weak light in the environment. Because the cat's retina has a bright blanket in front of it, and the cat's pupils will dilate in the dark, the amount of light received by the cat is only 1 6 of that of a human, and it can be seen clearly.
In fact, cats are very short-sighted, and their eyesight is only 1 10 of humans, so they cannot recognize particularly small things like humans. Although the cat is nearsighted, its sports vision is very good, even if the prey moves 50 meters away, the cat can also catch it, therefore, in the eyes of humans, it is a fast-moving object, in the eyes of the cat is just normal movement.
The outer side of the retina of a cat's eye has a layer of yellow cells called the choroid, which reflects light through the retina and has the effect of further enhancing the light. Even in the dark, with a faint light, cats can quickly focus on the movement of nearby prey (2-6 meters).
For natural hunters like cats, the ability to see clearly in low light and at night is important. Cats' eyes have greater peripheral vision than humans. The cat's field of view is about 185 degrees, and people can only see about 120 degrees.
Moreover, the cat's pupils can dilate to 90% of the surface of the eyeball in the dark, and the faint light is enough for them to hunt for prey. The ratio of cones in cats is 25:1, compared to 4:in humans
1. So when it turns to night, cats become more sensitive than humans.
This also explains why cats like to be diurnal and nocturnal, they start to be active in the evening and wake their owners very early in the morning. It's the cat's biological clock that makes it particularly active in these.
-
Yes. Cats have a different eye structure than humans and can see clearly even at night.
-
It's not just cats that can be seen at night, all four-legged animals, they can be seen at night, it's natural!

The cat can see it, otherwise how would it catch mice?

Cats can see at night because the cat's eye has a strong ability to collect light, the pupils can dilate at night, and there is a bright blanket structure in front of the retina, which can improve the utilization of light. However, cats need light to see at night, and cats can't see in complete darkness at night.
<> cat's eyes are very capable of collecting light, even if it is only a very faint light, their eyes can be gathered to see things clearly. At the same time, the cat's pupils will dilate in the dark, which is also conducive to the collection of light. In addition, the cat's whiskers can be used as a tool to measure distance and determine direction, and cats can move normally at night as they do during the day.
There is a structure called "bright blanket" in front of the cat's retina, which can reflect the weak light that enters the retina back to the retina, thus improving the utilization rate of light. However, cats also have to rely on light at night to achieve night vision, and if it is completely dark, cats cannot see.

Because a cat, his eyesight is several times that of our humans, he is particularly sensitive to light, so he can see a lot of things at night, which depends on a substance in his body is taurine, and cats are nocturnal animals, so for many cats at home, the problem of running around at night, we don't have to be very entangled.
The cat's eyes have a very large pupil, he can change the size according to the intensity of the light, if the light is strong, the pupil will become smaller, if the light is weaker, the pupil will become larger, so in the dark night the cat's pupils will become big and round, in the dark night can see a lot of things, are like mice This is a faster creature Cats are more interested, so it is not strange to catch mice, in the daytime because the light is stronger, cats do not like the place where the light is strong, It will make them feel insecure, so they basically hide from sleeping during the day. <>
Cats are sensitive to light and sound! His eyes can collect limited light, but if the cat is in a high-light environment for a long time, the cat is very unfriendly and will make the sensitive cat have a stress reaction! However, cats occasionally overturn at night because they are more excited when exercising, such as the sound of colliding with something, which will also make us hear clearly at night!
In life, we still have to leave a little light for the cat, or we can choose the kind of curtain that is not very good to avoid the body injury caused by the slow reaction of older cats! <>
If there are conditions at home, you can add more taurine to cats, such as mammalian organs, marine fish, shellfish, seaweed powder, taurine can regulate the central nervous system, maintain normal vision and cardiovascular function, but try to let the cat prey on its own, so that it can also exercise the cat's primitive hands-on ability can be described as killing two birds with one stone! <>

Cats are nocturnal creatures, and their night vision is innate.
The owl's eyeballs are tube-shaped, and some have described the owl's eyes as a microscopic telescope. In the retina of owl eyes, there are extremely abundant columnar cells. Styloid cells can sense light signals from the outside world, so the owl's eyes should be able to perceive very faint light. >>>More
Mosquitoes have eyes and occupy 3 4 of the head. As a result, mosquitoes have a wide range of perspectives and can see a wide range of things. Mosquitoes can also see infrared, so they can see at night and look for them accurately.
No. Because bees see a different spectrum than humans, they can't see red light (they may call what we call red light "yellow"). However, they can see shorter wavelengths of ultraviolet light, which is a very bright color for them, sometimes called "bee purple". >>>More
The causes of cataract are related to many aspects, and the specific circumstances are as follows: >>>More
I think it's light, the eye can see things because objects emit light or reflect light, and objects of different colors can reflect different colors of light, and this is related to the lens in the eye, because some people know that color blindness means that there is a problem with the lens.
