"Hahaha! Great! It's clear, it's clear! Through this little thing, I can clearly see the words on the newspaper again!"
Ying Zheng held his eyes and could clearly see the writing on the newspaper through the lenses. He was extremely excited.
"Great, I guessed that Fei Yu would have something to do!"
Lian'er was happy for him and also proud of her son.
"This thing is small and light, which is really good! It's just that these two stick-like things always block the two pieces of glass. It would be even more perfect without these two sticks!"
After Ying Zheng scanned the newspaper, he pinched the two folded spectacle legs and said.
"Father, the things in your hands are called glasses, and their function is to adjust your vision!"
Ying Feiyu didn't explain much, but took the glasses from Daddy Zha, put them on the bridge of his nose in the correct way, and showed a mocking smile.
"You...you brat, why didn't you tell me earlier?"
Ying Zheng naturally understood the meaning of his words, and immediately took the glasses over, imitating his movements, and carefully placed them on the bridge of his nose, "Hey! I feel much better this time!"
"Lian'er, where is yesterday's newspaper? Is it still there?"
After making sure that the glasses could allow him to see the small characters nearby clearly, he grinned and greeted.
"Yesterday's newspaper? Of course it was taken away by the palace staff! Why is Brother Zheng looking for that?"
The sudden question confused Lian'er.
"Quick! Quick! Find me quickly!"
Ying Zheng ordered happily.
"Uh...okay!"
Lian'er nodded and ordered her servants to do it.
After a while, a copy of yesterday's newspaper appeared in Ying Zheng's hand.
He quickly turned to the front page headlines, adjusted his glasses, and looked at it carefully.
Ying Feiyu thought he wanted to read how spring plowing was described in the newspaper, but unexpectedly, after a while, he said, "Yeah! The photo I took was pretty good!"
"Ahem..."
Ying Feiyu almost choked at his words.
The old guy Emotion hurriedly ordered someone to find the newspaper, just to see his appearance in the newspaper?
It's not the first time it's been in the newspaper, is it?
"Haha! The glasses you studied this time are really good! They easily solved the problem of blurry vision...!"
After putting down the newspaper, Ying Zheng gently pinched the temples of his glasses and took them off, "It's just that these two sticks are a little too thin. I'm really afraid that I won't use the right strength in my hands and bend them directly!"
"Yes! Father is right!"
Ying Feiyu nodded seriously.
"Huh? Why are you so cooperative this time? You usually find various reasons to criticize me!"
Ying Zheng was quite surprised.
"Because what my father said makes sense! These are the first reading glasses in the Qin Dynasty, and they are also the first glasses in the Qin Dynasty. The material of the temple legs was also found temporarily, and the quality is indeed average! When I turned around, I ordered people to change them. Thousands of years of black iron, changed to the thickness of an arm, this way, it will be absolutely foolproof and will not bend no matter how hard my father exerts it!"
Ying Feiyu said seriously.
"You...you kid did it on purpose, right? Can I still hold the thousand-year black iron that is as thick as my arm to the bridge of my nose?"
His words wiped away all Ying Zheng's previous good mood. He immediately rolled his eyes and complained to Lian'er, "Look, can you blame me for not speaking properly? Look at what this kid said. ?”
"Feiyu, talk to your father properly!"
Lian'er didn't hesitate this time, pretending to be angry and scolding her.
Ying Zheng heard this and stared at Ying Feiyu proudly.
Unexpectedly, Lian'er's next words came to him, "Brother Zheng, it's true! It's not easy for Feiyu to find a way to adjust Brother Zheng's eye disease in such a short period of time. The temples are so thin. For the sake of weight! Brother Zheng, just be careful when using your glasses!"
"Forehead……"
Ying Zheng pursed his lips and had nothing to say.
Because it is true, if the weight of his eyes and legs is increased for the sake of strength, his body will not be able to bear it!
"How did you make these glasses? Why so fast?"
In order to alleviate the embarrassment, he had no choice but to change the topic.
"Glasses are different from telescopes. They require a high degree of precision in grinding the lenses, so an edger is needed! This machine was originally built by Erchen to produce myopia lenses. It was just built recently. My father was the first to use it. of!"
Unlike Huang Yuan, Ying Heng and others, Zha Daddy had no interest in technology and would not ask any questions about this edger, so Ying Feiyu spoke out directly and generously.
"Myopia glasses? Are the glasses I use called myopia glasses?"
Ying Zheng knew nothing about these terms, but he just found them a bit strange.
"No, no, no! What my father is holding is called reading glasses, which have exactly the opposite effect to myopia glasses...!"
Therefore, Ying Feiyu gave a brief explanation on myopia glasses and reading glasses.
Ying Zheng and Lian'er heard this in confusion.
It seems like I understand, but it also seems like I don’t understand at all.
"Let's put it this way, what my father needs is to use his glasses to bring things close to him far away! For people with myopia, it is necessary to bring things far away close up!"
Looking at the two people's half-understanding expressions, Ying Feiyu gave another simpler example.
"I see……!"
Now Ying Zheng finally understood, "I have heard from many civil servants before that they can't see things in the distance clearly, but I still don't think so. Now that I think about it, this must be what you call myopia, right?"
"Yes, Wen Chen often stays up late reading, and the focus is always too close, so he suffers from myopia...!"
Ying Feiyu nodded firmly, "However, this also has an advantage, that is, you will no longer suffer from presbyopia!"
"Oh? So, people's eyes will have problems sooner or later, either myopia or presbyopia!"
After hearing this, Ying Zheng laughed helplessly.
"It can't be said that if you protect yourself well when you are young, you will naturally not be short-sighted! When you get older, you should also consider your physical fitness and situation. Some people will not be dazzled until they are seventy or eighty years old!"
Ying Feiyu said with a serious face.
"Alas! Then I am not so lucky! I escaped myopia, but I couldn't escape presbyopia...!"
Ying Zheng shook his head helplessly, "But fortunately, I have the treasure of glasses. I don't have to worry about reading newspapers in the future!"
"That's right!"
Ying Feiyu nodded firmly.
"That's right! According to what your kid just said, most people will need glasses! Then won't your kid make a fortune again?"
Ying Zheng suddenly remembered that this guy just said that he had built a lens grinding machine. Wouldn't he be able to continuously produce glasses in the future?
"Whether it's myopia or presbyopia, there are degrees of severity! If the condition is relatively mild, you don't need to wear glasses! It's uncomfortable to have something on your face all day long!"
Ying Feiyu shook his head and smiled.
