Hand over the jade seal first [Infrastructure]

Xiao Zirong never expected that after he revealed the news, not only did he not get the result he wanted, but he actually cheated himself.

Originally, he had persuaded Xiao Xuan to wait for a few more years, but now the prime minister and Shang Shuling suggested it together, it seemed that Xiao Xuan had the intention to do it now.

Xiao Zirong didn't understand, why?

Didn't he offend everyone before?

Let's talk about Xiao Yan first, he has too much enmity with Xiao Yan, if it weren't for him, Xiao Yan might be the emperor now, how could he still support him as the prince?

Don't say that if he becomes the crown prince, Xiao Yan can deal with him better, even a fool knows it's impossible.

After becoming the prince, he will be Xiao Yan's immediate boss in the future, so what exactly is Xiao Yan thinking?

Xiao Zirong always felt that there was something about it, but he hated that he was too far away from Xiao Xuexing, and after the telescope was sent over, Xiao Xuexing should have already started to arrange a counterattack, so he couldn't bother Xiao Xuexing with such things.

In the end, he had no choice but to put this matter aside and try his best to make Xiao Ji's glasses first.

The myopia mirror uses a concave lens that is different from a telescope, but it is similar to the telescope when it is made. The only thing that is not easy to grasp is the various degrees. This degree is bound to the thickness. This involves the principle of light refraction.

In later generations, various ultra-thin lenses have appeared in myopia glasses. Although they are expensive, they have basically abandoned the image of the bottom of a glass bottle.

It's a pity that the current technology can't reach it, so when the first lens was made, Xiao Zirong was completely dumbfounded holding that lens.

He thought about Xiao Ji's rather tall nose bridge, and deeply doubted whether his nose would be unbearable if he wore such glasses?

It's just that there is no need to think about how Xiao Ji will choose between the possibility that his nose can't bear it and the continued inability to see clearly.

What's more, Xiao Zirong also has his own selfishness, he is still waiting for Xiao Ji to put on his glasses and return to normal, and then use it as a shield for him.

So even though the lenses are thick, Xiao Zirong still asked people to continue making many lenses.

As for the fact that he did so much because he only had a rough estimate of Xiao Ji's degree, the eye chart was handwritten by himself. Although it was smaller than the eye chart in his mind, it could not completely guarantee the ratio.

At that time, it is still necessary for Xiao Ji to determine the degree of the other party while taking the vision test.

However, if you want to take a vision test, you need a frame.

The material of the mirror frame is still copper-iron alloy, and the outside is painted with a layer of paint to prevent rust.

In order to make Xiao Xuan's glasses look more cool, Xiao Zirong also made some decorations on the temples of the glasses, inlaid with dots of crystals, because the frame of the glasses is also made of gold, so the overall look is more shiny. so shiny.

This mirror frame can be regarded as a private order, all of which are made by superb craftsmen, and the patterns on it are all carved by hand bit by bit.

After making it, Xiao Zirong looked at the frame and thought it looked pretty, so he asked someone to create two more.

One pair is gold, which is relatively simple, but a gold chain is added on both sides of the temples, and the other is silver, which is also very simple, with waves painted on the temples with blue dye.

He kept these two pictures for himself and Xiao Xuexing. Although both of them have good eyesight, they can still wear plain glasses.

Even if it's just a frame, it's a decoration.

Xiao Zirong imagined how Xiao Xuexing would look like wearing glasses, um, it feels a little hard to imagine.

But he didn't just let people make these simple frames, he also made people make a frame specially used to test eyesight.

It's the same as when the patients in the later generations wear glasses, and then the lenses of different degrees can be inserted in the frames.

For more accurate glasses.

After the frames are finished, the lenses are almost the same, or the lenses used for glasses are almost the same. The rest has to be processed on site after Xiao Zirong confirms Xiao Ji's prescription, and the lenses are polished into suitable The shape of the mirror frame and then installed in it.

When testing his eyesight, Xiao Ji was very excited when he saw the pile of lenses brought by Ah Yin.

When he was guessing how to wear it, he saw Xiao Zirong took out a very strange thing, and then told him to sit still, and then the thing was put on his ears and the bridge of the nose.

Because there is no rubber in this era, the nose pads must not be made of rubber, so Xiao Zirong used a very special thing-amber in a very extravagant manner.

The texture of amber is neither particularly hard nor very soft. Of course, there are many things that can replace amber. At that time, he just thought that the color of amber matched the gold frame, so he got a few.

Xiao Ji touched the frame in front of him, feeling a little awkward.

Xiao Zirong was not in a hurry to test his eyesight, but just asked, "How does this feel?"

Xiao Ji felt it for a while and said: "It's okay, it was a bit awkward at first, but it's not a big deal."

Xiao Zirong was slightly relieved, it would be best if he could adapt.

This frame is not an ordinary frame, it is a bit heavier than an ordinary frame, and it is about the same weight as an ordinary frame plus lenses. If Xiao Ji can adapt to this weight, he will naturally be able to adapt to that after getting the glasses.

Xiao Zirong asked him to prepare, picked out a [-]-degree myopia lens from the box and inserted it into the frame, and then asked, "How do you feel now?"

Xiao Ji's eyes lit up immediately: "I can see a little more clearly!"

Perhaps because of excitement, his face was covered with a thin layer of blush.

Xiao Zirong pressed his body and said, "Don't be in a hurry, sit down, and now tell me which line is the most clear."

After Xiao Ji pointed it out to him, Xiao Zirong rummaged through it in his brain for a long time, and decided that he should continue to add at least two or three Baidus, and then directly pulled out the lens and replaced it with a seven Baidu lens

Xiao Ji's heart beat faster and said: "This is more clear."

Xiao Zirong clicked on the line with zero vision and asked, "How is it? Can you see clearly?"

Xiao Ji hesitated for a moment and said, "I can see it vaguely."

Xiao Zirong didn't take out this lens, but added another fifty degrees on top of this, and asked again: "Can you see clearly now?"

Xiao Ji nodded and said, "It's a little clearer than before."

Xiao Zirong continued to add [-] degrees to him, and by this time, Xiao Ji's glasses had reached [-] degrees, which was similar to what he judged before.

But there is still no way to correct the vision, let alone correct it to the best, but it is not enough to reach the daily standard.

Xiao Zirong continued to increase the reading with some doubts, and after adding another two hundred degrees, he could barely see clearly.

He felt something was wrong, and asked directly: "How do you feel when you look at it? Is it a mess or something?"

Xiao Ji tried hard to describe his feelings: "It's just that the edges are a bit blurry. It's been like this since the beginning. Later, I added lenses a few times to get better, but the effect is not particularly good, and I feel dizzy after wearing it."

Dizziness means that the prescription is not suitable, but you still can't see clearly... Xiao Zirong asked him to take off his glasses, thinking that he might have overlooked something.

First of all, it is confirmed that Xiao Ji is definitely not farsighted, and then there are no other obvious symptoms of eye diseases, it seems to be pure myopia, then there should be no problem in this case, is it because the lens is not made to a standard?

But it can still be seen clearly when the standard reaches the appropriate degree.

Xiao Zirong thought about it seriously for a long time, and then started to search for the entry of vision correction. After a glance, he couldn't help but touch his forehead: He finally knew what was wrong, and he just ignored the possibility of astigmatism for a long time. .

Amblyopia, hyperopia, and myopia basically do not exist at the same time, but astigmatism will overlap with them, especially many people who suffer from astigmatism while myopia.

Xiao Ji should be in the same situation at present.

And astigmatism lenses... He didn't study them.

Seeing Xiao Zirong's frown, Xiao Ji said, "Brother, it's good now, at least I can see most of it clearly, don't embarrass yourself."

Xiao Zirong frowned and said: "It's nothing, I overlooked one thing, my brother's eyes have two diseases superimposed, so this lens needs to be done again."

The degree of myopia plus the degree of astigmatism, he only knows that there seems to be some prism positioning method, and he needs to test it a little bit.

But astigmatism is different from myopia, he doesn't have much evidence, and then he can only test with simple astigmatism lenses and myopia lenses to see how much Xiao Ji's astigmatism degree is.

Xiao Ji was not surprised when he heard that the two diseases were superimposed. If his eyes were so easy to treat, he wouldn't be able to pin his hopes on his younger brother.

Even if he couldn't find someone capable enough in the past 20 years, but after that he was a prince, and his father hired many famous doctors for his eyes, even the folks in the palace, but it was useless.

Xiao Ji was a little uncertain and asked: "Then... can it be cured?"

Xiao Zirong smiled and said: "Don't worry, it's ok, hey, forget it, anyway, I have time anyway, so I'll tell you about your situation seriously."

Xiao Zirong felt that as a patient, it was necessary for Xiao Ji to know a little about myopia, so that if his myopia deepened in the future, he would be able to detect it in time, and then get glasses again.

Xiao Zirong carefully explained to Xiao Ji while copying down the production method and precautions of the astigmatism lens.

Xiao Ji didn't quite understand at first, what he didn't understand was that Liuli could be seen clearly by making a special shape?

Xiao Zirong had no choice but to teach him all kinds of light knowledge from the beginning, of course it was limited to glasses, otherwise he would only have to teach Xiao Ji for a month before he could get started in this area.

Theoretical knowledge related to light is easy because light is everywhere, and Xiao Zirong can easily do an experiment to prove his statement.

Xiao Ji is obviously also very interested, even if the glasses are not finished yet, he needs to get close to Xiao Zirong to see those experiments clearly, he doesn't find it troublesome.

After the explanation was almost finished, he began to explain the structure of the human eye, focusing on refractive correction.

These things have been studied by the predecessors for a long time, and Xiao Zirong doesn't need to let Xiao Ji know a lot, as long as he knows.

While casually explaining these knowledge to Xiao Ji, he stared at the production of astigmatism lenses.

After the astigmatism lens was finished, Xiao Zirong weighed it. I don't know if it was his illusion, but he always felt that the lens seemed to be much thicker after adding the astigmatism degree.

The test of astigmatism is almost the same as that of myopia. After the test, Xiao Ji's astigmatism is about two hundred degrees, which is not very high.

After the degree is determined, it is much easier to make glasses.

On the day when the glasses were finished, Xiao Xuan came over to watch immediately after getting the news, and it turned out that not only him, but also Xiao Yan Chaihe and others followed.

When Xiao Zirong took out the glasses, everyone looked around curiously. Not to mention, although the glasses looked weird, they were really pretty.

After Xiao Ji put on the glasses, his already gentle demeanor became more refined and refined, making him appear more elegant.

But that's not the point, Xiao Xuan looked at his son nervously and asked, "How is it? Can you see clearly?"
