The cat’s eyes are very beautiful, they look like crystal clear gems, and they look so charming.

Do you know everything about cat eyes?

What is the difference between the world in a cat’s eyes and the world in our eyes?

Today, Xiao 8 will tell you about the knowledge about cat eyes!!!

Knowledge 1: Eye Color

Almost all cats have blue-gray eyes when they are born.

This is because when cats are born, their eyes are covered with a blue film.

As it grows up, this film will slowly disappear and different colors will appear.

As for the final color, it depends on the breed of cat.

Knowledge 2: Night vision ability

Cats can travel freely at night, which is all due to their super night vision ability. The light required for cats to see objects clearly at night is only 1/6 of what humans need.

To maintain this superpower, cats need to obtain enough taurine. Taurine is contained in cats’ main prey, fish and mice. A certain amount of taurine is also added to current cat food.

So don’t worry about domestic cats’ night vision being weakened.

It is said that because of this "superpower", cats can also see things that humans cannot.

Of course, this is just a joke, O(∩_∩)O haha~

Knowledge Three: Color Weakness

Cats all have the problem of "color weakness". They can only see blue, yellow and green, but not red.

Although cats cannot distinguish all colors, it does not prevent cats from catching prey, so color weakness is not a big problem.

The color of the world in our eyes is what it looks like at the top of the picture, while the color of the world in a cat’s eyes is what it looks like at the bottom of the picture.

Knowledge 4: Hyperopia

Compared with humans, cats are farsighted. Generally speaking, they cannot see clearly objects that are less than 30 centimeters away.

Then why do cats react when you use a cat teasing stick to tease them?

This is because cats are born with a keen sense of moving objects.

Knowledge Five: Dynamic Vision

Cats have very strong dynamic vision, which is as good as human vision.It is 25 frames per second, which is also the frame rate setting for most movies and TV series.

So the movies and TV series that seem smooth to us look like PPTs to cats.

For cats to see smoothly, it needs to reach at least 100 frames per second.

Knowledge 6: Don’t blink for a long time

Human beings need to blink every few seconds to keep their eyes moist.

Cats, on the other hand, can not blink for a long time because there is a third eyelid in the cat's eyes, also called the "nictitating membrane".

It can keep the eyes moist, so the cat can go for a long time without blinking.

Knowledge 7: Field of View

The human visual field range is 120 degrees, while the cat's visual field range can reach 200 degrees.

So if you want to "sneak attack" the cat without being discovered by it, you can only quietly touch it from directly behind.
