"Hahaha! It's great! It's clear, it's clear! Through this little thing, I can clearly see the words in the newspaper!"

Ying Zheng held his eyes in his hand, and through the lens, he could clearly see the handwriting on the newspaper, which was extremely excited.

"That's great, I guess Feiyu will have a solution!"

Lian'er was happy for him and was also proud of her son.

"This thing is small and light, and it's really good! But these two sticks always block the two pieces of glass. If you don't have these two sticks, it would be even more perfect!"

Ying Zheng swept around the newspaper and said, clamping the folded legs of the glasses.

"Father, what you have in your hand is called glasses, which is used to regulate your vision!"

Ying Feiyu did not explain too much, but took the glasses from the scumbag's hand and put them on the bridge of his nose in the correct way, while showing a sarcastic smile.

"You...you guy, why didn't you say it earlier?"

Ying Zheng naturally understood what he meant, and immediately took his glasses over, learned his movements, and carefully put them on the bridge of his nose, "Hehe! I feel much better this time!"

"Lian'er, where is the newspaper yesterday? Is it still there?"

After confirming that his glasses could let him see the small words in the vicinity, he grinned and greeted him.

"Yesterday's newspaper? Of course, it was taken away by the palace servant! Why did Brother Zheng look for that?"

Suddenly asked, confused Lian'er.

"Hurry! Hurry! Come find me now!"

Ying Zheng happily ordered.

"Uh... OK!"

Lian'er nodded and ordered the servants to do it.

After a while, a newspaper from yesterday appeared in Ying Zheng's hands.

I quickly turned to the front page headlines, held my glasses, and looked carefully.

Ying Feiyu thought he wanted to read how the spring farming was described in the newspaper, but unexpectedly, after a while, he said, "Well! I took a good photo for me!"

"Ahem..."

Ying Feiyu almost choked by his words.

In love, this old guy was so anxious that he ordered people to find newspapers just to see how he looked in the newspaper?

This is not the first time I've been in the newspaper, so?

"Haha! The glasses you guy researched this time are really good! It easily solved the problem of vague viewing...!"

After putting down the newspaper, Ying Zheng gently pinched his glasses and took them off. "But these two sticks are a bit too thin. I am really afraid that the force on my hands is not used correctly, so I pinched it directly!"

"Well! What the father said is reasonable!"

Ying Feiyu nodded seriously.

"Oh? Why are you so cooperative this time? You always find various reasons to criticize me!"

Ying Zheng was quite surprised.

"Because what the father said really makes sense! This is the first reading glasses in Daqin and the first glasses in Daqin. The materials for temples were also temporarily searched, and the quality is indeed average! After turning around, the minister ordered people to change it to a thousand-year-old black iron, and the thickness to an average arm. In this way, it will definitely be foolproof. No matter how much strength the father uses, it will not bend!"

Ying Feiyu said seriously.

"You... you kid did it? Can I still put the thousand-year-old black iron as thick as an arm on the bridge of my nose?"

His words wiped out 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 well? Look at what did this kid say?"

"Feiyu, speak to your father!"

Lian'er was not vague this time and started to scold him in anger.

When Ying Zheng heard the sound, he glared at Ying Feiyu proudly.

Unexpectedly, Lian'er's next words came to him, "Brother Zheng is really! It is not easy for Feiyu to think of a way to adjust Brother Zheng's eye disease in such a short time. The thinness of the glasses is also for weight considerations! Just be careful when using glasses!"

"Forehead……"

Ying Zheng flattened his mouth and had nothing to say.

Because this is true, if the weight of the eyes and legs is increased to be strong, his body will not be able to bear it!

"How did you make these glasses? Why are you so fast?"

In order to alleviate the embarrassment, he had to change the subject.

"Glasses are different from telescopes. They require a high degree of fineness of lens polishing and require an edge grinding machine! This machine was originally built to produce myopia glasses, but it has just been built recently. The father was the first to use it!"

Daddy is different from Huang Yuan, Ying Heng and others. He has no interest in technology and will not ask the bottom of this edge grinder at all, so Ying Feiyu said it straight and generously.

"Myopia glasses? Are the glasses I use called myopia glasses?"

Ying Zheng knew nothing about these nouns, but he just thought it was a little strange.

"No, no, no! The one in my father's hand is called reading glasses, which are exactly the opposite of the effect of myopia glasses...!"

So, Ying Feiyu gave a brief explanation of myopia glasses and reading glasses.

Ying Zheng and Lian'er were listening to the clouds and fog.

It seems to understand, but it seems to not understand at all.

"Let me put it this way, what the father needs is to pull the things near to the distance through glasses! For people suffering from myopia, they must pull the things far away close to the distance!"

Looking at the expressions of the two who seemed to understand, Ying Feiyu gave another simple example.

"I see……!"

Now Ying Zheng finally understood, "I have heard many civil officials say that they can't see things in the distance clearly. I don't think so. Now I think about it, this should be what you call myopia, right?"

"That's right, civil officials often stay up late to read books, and the focal length is always too close, so they suffer from myopia..."

Ying Feiyu nodded firmly, "However, there is also an advantage in this, that is, he will not suffer from presbyopia again!"

"Oh? In this way, people's eyes will sooner or later have problems, 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 myopic! When you get older, you must also combine your physical fitness and situation. Some people will not be dazzled until they are in their seventies or eighties!"

Ying Feiyu said with a serious face.

"Oh! Then I don't have this blessing! I avoided myopia, but I couldn't avoid presbyopia...!"

Ying Zheng shook his head helplessly, "But fortunately, with the treasure of glasses, I won't have to worry when I read the newspaper in the future!"

"That's right!"

Ying Feiyu nodded firmly.

"By the way! According to what you guy just said, most people will need glasses! Then, aren't you guys going to make a big profit again?"

Ying Zheng suddenly remembered that this kid had just said that he had built a machine for grinding lenses. Will he be able to continuously produce glasses in the future?

"Whether myopia or presbyopia are different from the severity of the degree! If the situation is relatively mild, you don't have to wear glasses! It's uncomfortable to have something on your face all day long!"
