"Hahaha! That's great! Clear, clear! Through this little thing, I can clearly see the words in the newspaper again! ”

Ying Zheng held his eyes in his hands, and through the lenses, he could clearly see the handwriting on the newspaper, and he was very excited.

"Great, I guessed that Fei Yu would have a way!"

Lian'er is happy for him, and at the same time proud of her son.

"It's small and lightweight, and it's really good! It's just that these two stick-like things always block those two pieces of glass, and it would be even more perfect without them! ”

After scanning the newspaper, Ying Zheng pinched the two glasses that were folded together and said.

"Father, the thing in your hand is called glasses, and its function is to regulate your eyesight!"

Ying Feiyu didn't explain too much, but took the glasses from the scumbag father's hand, put them on the bridge of his nose in the correct way, and showed a mocking smile at the same time.

"You...... You stinky boy, why didn't you say it earlier? ”

Ying Zheng naturally understood the meaning of his words, and immediately snatched his glasses, learned his movements, and carefully put them on the bridge of his nose, "Hehe! It feels so much better this time! ”

"Lian'er, what about yesterday's newspaper? But still? ”

After making sure that his glasses would allow him to see the small print in the vicinity, he grinned.

"Yesterday's newspapers? Naturally, it was taken away by the palace people! What is Brother Zheng looking for? ”

Suddenly asked, and Lian'er was confused.

"Quick! Fast! Hurry up and get me! ”

Ying Zheng commanded happily.

"Uh...... Good! ”

Lian'er nodded and instructed her subordinates to do it.

After a while, a copy of yesterday's newspaper appeared in Yingzheng's hand.

quickly flipped to the front page, lifted his glasses, and looked carefully.

Ying Feiyu thought he wanted to see how the newspaper described spring ploughing, but he didn't expect that after a while, he said, "Hmm! It's not bad to shoot me! ”

"Ahem......"

Ying Feiyu was almost choked by his words.

Feelings: This old guy is in a hurry to find the newspaper, just to see what he looks like in the newspaper?

It's not the first time it's been in the newspaper, is it?

"Haha! Your kid's glasses for this study are really good! It easily solves the problem of blurry vision......! ”

After putting down the newspaper, Ying Zheng gently pinched the leg of his glasses and took it off, "It's just that these two sticks are a little too thin, I'm really afraid that the strength in my hand is wrong, so I will pinch it directly!" ”

"Hmmm! What my father said is reasonable! ”

Ying Feiyu nodded seriously.

"Yoh? Why are you so cooperative this time? I usually find all kinds of reasons to be scared! ”

Ying Zheng was quite surprised.

"Because what my father said does make sense! This is Daqin's first reading glasses, and it is also Daqin's first glasses, and the material of the temples is also temporarily searched, and the quality is indeed average! When he turned around, his son ordered someone to change it to a thousand-year-old black iron, and the thickness was changed to an arm, so that it would be foolproof, no matter how hard the father and emperor used, it would not bend! ”

Ying Feiyu said seriously.

"You...... You're a kid, aren't you? The thousand-year-old black iron with the thickness of my arm, can I still put it on the bridge of my nose? ”

His words swept away all the good moods before Yingzheng, and he immediately rolled his eyes and complained to Lian'er, "Look, can you blame me for not talking well?" What do you see this kid saying? ”

"Fei Yu, talk to your father well!"

Lian'er was not ambiguous this time, and pretended to be annoyed and reprimanded.

When Ying Zheng heard this, he glared at Ying Feiyu proudly.

Unexpectedly, Lian'er's next sentence came at him, "Brother Zheng is really good!" It is not easy for Fei Yu to think of a way to adjust Brother Zheng's eye disease in such a short period of time, and the thin temples are also for the sake of weight! Brother Zheng is careful when he uses glasses! ”

"Forehead ......"

Ying Zheng flattened his mouth and had nothing to say.

Because it is true, if he increases the weight of his eyes and legs for the sake of strength, then 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 to change the subject.

"Glasses are different from telescopes in that they require a high degree of fineness in lens polishing, and you need to use an edge grinder! This machine was originally built for the production of myopia glasses, but it has just been built recently, and my father was the first to apply it! ”

Unlike Huang Yuan, Ying Heng and others, the scumbag has no interest in science and technology, and he will not get to the bottom of this edging machine at all, so Ying Feiyu said it directly and generously.

"Myopia? Could it be that the glasses I use are called myopia? ”

Ying Zheng didn't know anything about these terms, but he just thought it was a little strange.

"No, no, no! What my father holds in his hand is called reading glasses, which is exactly the opposite of the effect of myopia glasses......! ”

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

Yingzheng and Lian'er listened in the clouds.

It seems to understand, but it seems that it doesn't understand at all.

"Let's put it this way, what my father needs is to pull something close to him into the distance through his glasses! For people with myopia, it's important to pull things from afar to closer! ”

Looking at the expressions of the two who seemed to understand whether they understood or not, Ying Feiyu gave a more obvious example.

"I see......

Now Yingzheng finally understood, "I have heard a lot of Wenchen say that I can't see things in the distance clearly, and I still don't think so, now that I think about it, this should be what your kid said about myopia, right?" ”

"That's right, Wenchen often stays up late to read, and the focus is always too close, so he suffers from myopia ......!"

Ying Feiyu nodded his head, "However, this also has an advantage, that is, you won't suffer from presbyopia anymore!" ”

"Oh? In this way, sooner or later, people's eyes will have problems, either myopia or presbyopia! ”

After Ying Zheng heard this, he laughed helplessly.

"I can't say that, if you protect yourself well when you're young, you won't be short-sighted! When you get older, you should also combine your physical fitness and situation, and some people will not be dazzled until they are seventy or eighty years old! ”

Ying Feiyu said with a straight face.

"Alas! Then I don't have this blessing! Escaped myopia, but not ...... presbyopia! ”

Ying Zheng shook his head helplessly, "But fortunately, with the treasure of glasses, I don't have to worry about reading the newspaper in the future!" ”

"That's right!"

Ying Feiyu fixed his head.

"That's right! According to what you kid just said, most people will need glasses! Isn't that about to make a lot of money again? ”

Ying Zheng suddenly remembered that this kid had just said that he had built a machine for grinding lenses, wouldn't he be able to produce glasses in a steady stream in the future?

"Whether it's myopia or presbyopia, there are degrees of severity! If the situation is relatively mild, you don't need to wear glasses! It's uncomfortable to have something on your face all day! ”

Ying Feiyu shook her head and smiled.
