"Discomfortable? I don't think so!"

Ying Zheng put his glasses on the bridge of his nose again, felt them carefully, and finally shook his head.

"That's because the father has worn it for a short time, and this thing is the first time I have developed it, and it has a strong sense of freshness! After the father has worn it for a long time, there will be no freshness. At that time, the glasses will be thrown aside by the father! Only when it is used will they be picked up!"

Ying Feiyu said with a smile.

Glasses are not new things in later generations. Unless they are absolutely necessary, no one is willing to wear them!

"Haha! Maybe, at least I think it's very convenient now!"

Ying Zheng held up his glasses, not only did he not feel troublesome, but he felt it was very cool.

This is Daqin's first pair of glasses, and no one else has it!

With such a new thing, I have to find an opportunity to show off to his old subordinates!

"By the way! How much do you plan to sell for these glasses? Can ordinary people afford it?"

Glasses are convenient, but if the price is too high and ordinary people cannot afford them, their convenience will not be well utilized.

"Now there is only one edge grinder, and the glasses that can be produced every day are very limited, so the price will naturally not be too low. After the edge grinder is made in the future, the production volume of glasses will increase significantly, and the price will also drop accordingly! At that time, Erchen will add several more materials to create glasses of different grades!"

Since the edge grinder is made, it must be researched and manufactured by Huang Yuan and others.

If you only hope to produce this machine, you will never be able to meet the needs of the entire Daqin!

With the character of a scumbag father, he will definitely not use it quietly after he has glasses. It is estimated that it will be known to everyone in the palace before it gets dark.

It won’t take long to spread the entire Xianyang and then slowly spread.

There will definitely be many people asking about glasses at that time!

"Then... are the lowest-grade glasses of the glasses very poor in quality? They won't cause any harm to people's eyes, right?"

Ying Zheng did not know what grades were not, but he just did not want to harm the people.

Glasses are made to make the people see more clearly. If it backfires, it will be bad!

"Don't worry, my father! Glasses are produced by my sons. If wearing glasses causes harm to the people's bodies, then the people will definitely feel resentful, which will have a solid impact on the stability of the Qin Dynasty! My sons can still be clear about these pros and cons!"

Although the father and son often quarrel, when talking about these serious things, they are still very serious.

"That's good!"

After hearing this, Ying Zheng felt much more at ease.

"Glasses are composed of two parts: lenses and frames. The grades are distinguished later, that is, the materials of these two parts are different! The effects of use are the same...!"

In order to reassure Bada, Ying Feiyu said more in detail, "For example, high-end lenses are clearer, and the frames are lighter and tougher! The clarity of low-end lenses may be slightly worse, and they need to be carefully maintained, otherwise they will also scratch! The frames are not that light and comfortable, and the feeling of wearing will be worse!"

The glasses have just been made now, and the material of the frame is not perfect.

As the lenses and frames are gradually upgraded, there will definitely be multiple materials in the future.

This can be used to distinguish the level of the grade!

"It's okay, as long as it won't hurt your eyes!"

Ying Zheng nodded repeatedly.

The poor people's family has little money left, so it is already very good to improve their vision. They will not pursue any best materials!

No matter how good the materials are, the use is to see things clearly!

For most people, economical benefits are the best!

Unlike wealthy families, they compare with each other and choose good quality when buying anything!

“Absolutely not…!”

Ying Feiyu promised confidently, "My son plans to produce it in small quantities first and sell it to ministers in need in the court! The ministers are busy with official duties every day and cannot see the official documents clearly! In addition, this is also a small experiment! If the ministers use it, it will definitely be fine for the people to use it in the future!"

"Well! You guys are more careful! The production of glasses is relatively small now, so you should indeed use them for the ministers in the court first!"

Ying Zheng praised his decision repeatedly.

Although the name is still "this kid", at least there is a smile on his face, no longer a beard blowing and staring at the eyes!

"Lian'er, look at these glasses..."

Ying Zheng stood up, took off his glasses, and wanted Lian'er to take a closer look.

While taking off your glasses and taking the first step, you felt dizzy and your feet became soft and you almost fell to the ground.

Fortunately, Ying Feiyu quickly supported him, otherwise Ying Zheng would have to fall into a blue nose and a swollen face!

"Brother Zheng, what's wrong with you? Wasn't you doing well just now...?"

Seeing this, Lian'er suddenly panicked and hurriedly called the eunuch, "Hurry! Go and pass on the imperial doctor!"

"yes!"

The eunuch was also frightened, responded, and was about to run out in a hurry.

"stop!"

Before he could go out, he was stopped by Ying Feiyu's order.

"Flying Feather?"

Lian'er stared at him in confusion.

"Mom, don't worry, Father is fine..."

Ying Feiyu smiled confidently and continued, "The reason why my father suddenly felt dizzy was because he wore glasses for the first time and took them off just as he got used to it, causing a short mental trance, which had no effect on his body, and he would recover later!"

"Can……"

"Lian'er, it's okay! Fei Yu is right. I was really confused because I took off my glasses just now. There was no other discomfort in my body. I'm already much better now!"

Lian'er was about to say something, but was stopped by Ying Zheng.

After you have fixed your body, you can stand by yourself, and at the same time you have doubts about your glasses. "Is this happening every time you take off your glasses in the future? Isn't that dangerous?"

For example, walking on the street, taking off your glasses due to some situation, causing dizziness.

Once there is a galloping carriage or car at this time, the consequences will be unimaginable!

"Haha! No! The reason why the father had this situation was that he had never worn glasses before and was not used to it. The second was that he did not carefully measure the degree before fitting glasses for his father, but was configured according to his age. Now it seems that the father's vision cannot reach this degree. I will measure the father's emperor and change the glasses slightly!"

After some explanation, Ying Zheng understood something, "What you mean is that my eyesight is not as bad as that of an ordinary person in his fifties?"

"Haha, I can say that! But the most important reason is that my father has not adapted to glasses. If he has been wearing them for a long time, this will not happen!"
