Have you ever had the following personal experience:

When you woke up late at night and peed, you turned on the flash of your phone to save power. As soon as you got off the ground, you found that there were a few beams of emerald green or light yellow flashing light coming towards you.

I took my family dog to have fun at night. Seeing the dog's likable look, I took out my phone and took a few photos (built-in photo flash). As a result, when I opened the photo, I saw that the dog's eyes were filled with dazzling light, and I had no choice but to delete it.

How could the dog's eyes become so shining at night!

Where the hairy child's eyes shining at night belong to the shiny or return to the light?

When it comes to shiny eyes, most people are not likely to believe it. Therefore, everyone feels that the eyes of the hairy children are so bright at night because they return to light.

However, at night, the return light can only reflect the moonlight, the galaxy and other very weak light that enters the eyes of the hairy child.

The compressive strength of this light in a dark night is too weak, so weak that people cannot see it. Therefore, people must have flashlights when traveling at night. According to basic common sense, the compressive strength of light after such weak light is reflected should be weaker.

But how can people see reflected light after experiencing the eyes of hairy children?

——Is it said that the incident light is powerful after being reflected by the hairy child’s eyes?

Why does it happen in broad daylight, and when the incident light from the outside increases, the hairy child's eyes no longer shines?

What is even more puzzling is that people who are careful to find that the eyes of a hairy child do not always have a shining light at night. Only when they have to use their eyes to search for the overall target will the eyes suddenly flash a bright cold light.

How did this happen in a while?

Are hairy children's eyes "intelligent instruments and equipment" that can be manipulated by the human brain?

There is a saying that they have a very unique TPE on their eyes, which can first gather the very weak light in the night, then reflect it out, and then see the items in the dark.

The appearance of this TPE can be manipulated by the muscles around the eye, and then the rebate rate can be adjusted according to the different compressive intensity of the external light.

But why is reflected light brighter than incident light?

- Does the eyes of small animals have the effect of storing light until they accumulate to a certain level and will be released?

It is obvious that such thoughts are absurd.

has a unique visual organ, choroidal blanket (tapetum)

The eyes of hairy children often become too bright at night. Because their periophthalmic structure is different from those of people, they have a unique human organ in their eyes - choroidal blanket (tapetum)

The choroidal blanket is located behind the macular side of the fundus, and its function is very similar to a bathroom mirror.

The bright surface of the choroidal blanket can reflect light that light that light-sensitive somatic cells do not receive back to the macula of the eye, allowing light-sensitive somatic cells to have a second chance to receive light when the light is dark.

The choroidal blanket can even penetrate the optical condition called [结] to make the light stronger and stronger. The bright light not only makes the light brighter, but also slightly changes the color tone of the light when it reflects home, making it more closely related to the most sensitive and detectable light wavelength of the light, that is, light green.

Moreover, the hairy child's eyes shine at night, not simply reflecting the extremely weak invisible light in the night. The key is that it also reflects infrared sensing that human eyes cannot see. Moreover, when the infrared sensing is reflected, it produces blue shift and becomes invisible light.

Summary:

●The reason for the hairy child is: unique to people's surrounding eyes;

●External reason: the overall natural environment is dark, and it is easier to highlight brightness;

●People's own reason: people's light-sensing somatic cells are cylindrical somatic cells at night, and their sensitivity is improved.

Therefore, people see hairy children at night and shine.

Confusion in "Titanium Dog Eye"

Although the light reflected from the choroidal blanket can make the eyes more alert, it also comes at a price.

The light that jumps back home from the choroidal blanket comes from all directions, just like when a billiard ball encounters the edge of a pool table, it is not easy to return with the same line, but pops up from another perspective. Because the light enters the eye's direction and the bounce area, the images on the macula of the eye will become blurred and look blurry.

Therefore, the dog's eyes can see more clearly in the dark natural environment, and choose to sacrifice the ability to see small key points.

The unique structure of puppy's eyes also makes the puppy's eyes very sensitive to light at night.

Just like when people were at night, many people suddenly turned on the headlights of the car, and people felt that they were blind, and the puppy's eyes were more sensitive to the light at night.

And scientific research shows that the puppy's eyes undergo long-term strong light irritation will increase the chance of disease by about ten times, which can be said to be a very high level.

Therefore, cat slaves must protect the dog's eyes and reduce the irritation of puppies' eyes.

●Reduce the puppy to play with some flash toys;

● Adjust the lighting effect at home. Excessive lighting effects are often harmful to puppies and people's human bodies;

● Usually, you often take puppies to see the sunlight.

Now it is clear that the puppy's eyes emits a mysterious light~
