Li Wenchong nodded: "Well, the emperor asked me to enter the palace for this. He secretly asked someone to investigate. There were many old ministers in the court who had problems with their eyes. It was because of this that Taifu Cao found an excuse to 'rob' the magnifying glass of the eldest prince' Ang Lee... I was called to enter the palace later, and you also sent ten magnifying glasses into the palace, remember?"

"Didn't Grand Tutor Cao teach her a lesson?" Gu Qingling remembered that when Li Wenchong came back, he told her that.

Gu Qingling didn't think much about it. She thought that it was normal for her husband to focus on educating people and to give children a "learning" or something.

But now it sounds like this is not the case?

"Yes, what Grand Tutor Cao said at that time. Later, it was not a mistake. The emperor thought it was wrong, so he called Grand Tutor Cao over and asked. This time, Grand Tutor Cao did not hide it and admitted his guilt with the emperor. If he hadn't recognized the realm himself, who would have thought that Grand Tutor Cao confiscated the magnifying glass of the grandson of the emperor, Ang Lee, in fact, it was not for punishment, but for his magnifying glass?"

Gu Qingling's mouth twitched.

Indeed, it is indeed a bit too much for an adult to go to grab a child's "toy".

"So later, the emperor sent someone to investigate the ministers in the court. How many people had their eyes problems? The result was not checked and they were shocked. There were still many people with their eyes problems. But they all concealed something and were not exposed."

Gu Qingling was puzzled: "Since there is something wrong with your eyes, how can you not see it? Doesn't this affect your normal life?"

"It's normal for you to be older, you have physical problems and do things slowly. Besides, no matter what it is, they don't have to do it themselves. Just follow a few officials around you and ask them to help. Read a memorial, help write something on your own, and check it out for yourself... They just have a worse vision, they are not really invisible, they just have an impact, and they are not unable to work at all."

"So that's the case. In fact, whether there is a magnifying glass or not has a big impact on them. But if there is a problem with your eyes, it is a problem with your eyes, which is somewhat uncomfortable." Gu Qingling thoughtfully said, "If there is no solution, then forget it, everyone can handle it. But if you know that there is a solution, you will definitely flock to find a way to solve it."

"Well! So the emperor discussed with me, and wanted to take advantage of the news that the old ministers would ask him to lend you the craftsman workshop in your hand and make a magnifying glass. So that someone would really come to ask for it, and he had nothing to give it away." Li Wenchong said, "Don't worry, the emperor will not let you do it in vain. Just discount the amount of money a pair of magnifying glasses, just give it to him."

Gu Qingling laughed: "The magnifying glass is not worth much. It's all made of glass, it just takes some effort... The main problem is not this, but the factors that cause problems in each person's eyes are different. If you use one thing, it may not solve everyone's problems."

As he said that, Gu Qingling paused, "This way, I have a few things in my hand. You can find someone to try it out and see how it works. If the effect is possible, we will find someone to cooperate and open a glasses manufacturer near the capital."

Gu Qingling dipped her fingers in tea and wrote the five words "glasses manufacturer" on the desktop, which made Li Wenchong understand which glasses she was talking about.

"Glasses? Mirrors for eyes? Does this mean?"

"It's almost the same. The correct statement should be the lenses used for eyes, not mirrors, but lenses."

“It’s quite appropriate.”

...

After a while, Gu Qingling asked someone to take a few pairs of glasses she had collected.

"This is reading glasses, which are used by the elderly. There is a problem with the eyes of the elderly, which is different from young people. The elderly usually cannot see small characters clearly, and they will unconsciously tilt their heads back, or take the book a little further before they can see clearly. Moreover, as the age of affluence increases, the distance they take will become farther and farther... This is generally presbyopia." Gu Qingling said, and handed the glasses marked "reading glasses" to Li Wenchong. "So, this glasses specifically for this type are called 'reading glasses', and a convex lens is added. You can try this kind of glasses."

"What about this?" Li Wenchong took the reading glasses and pointed to the box that was close to the "myopia".

"This is different. The symptoms of insufficient qi and blood, which consume blood for a long time. Blood is the mother of qi. Blood is also weak and qi is also weak. The divine light cannot be emitted farther away. The diagnosis is based on excessive use of eyesight and blurred vision. The liver and kidney deficiency syndrome is insufficient, and the yang is weak and yin is so that the light cannot be farther away, so I can't look near but not far away. Generally speaking, myopia is more likely to occur in young people who use their eyes improperly."

Li Wenchong was surprised. He really didn't know that in this world, there are not only the "presbyopia" of the elderly, but also "myopia"?

Presbyopia can only be "long-sighted" and cannot see clearly if it is too close; while myopia can only be "long-sighted" and the two are just the opposite.

Of course, presbyopia does not mean "hyperopia", it is still different from real hyperopia.

Presbyopia is just because they get older and some of the functions of their eyes become worse, which makes it difficult to see things that are too close to them.

Age issues cannot be avoided.

But hyperopia is not necessarily related to age, there are other factors involved.

Gu Qingling only learned a brief lesson about medical issues and couldn't explain them clearly, but overall, Li Wenchong also understood what was going on.

So Li Wenchong held Gu Qingling and gave him two boxes of glasses and found someone to try it out.

Although no one in the court is willing to admit that he has bad eyes, no problem, does Taifu Cao have "presbyopia"?

Without saying a word, Li Wenchong directly looked for Taifu Cao.

"Teacher Cao, try this, this should be better than a magnifying glass." Li Wenchong took a pair of reading glasses marked "1" to give it to Taifu Cao.

This chapter is not over, please click on the next page to continue reading! Although Grand Tutor Cao was a little surprised by Li Wenchong's arrival, he saw that the other party came for his own eyes. When he thought that it might be revealed by Emperor Mingguang, he could only "accept it" with a smile.

Taifu Cao didn't have much hope. After all, a magnifying glass is already a miracle. How could a second miracle appear so soon?

Taifu Cao learned what he saw on the manual and put No. 1 reading glasses on his face.

"Teacher Cao, are you dizzy? Can you see clearly?" Li Wenchong reached out and shook his hand in front of Taifu Cao.

Although they are reading glasses, reading glasses also have a degree of degree.

Li Wenchong was not sure about the specific situation of Grand Tutor Cao's eyes, so he could only try it with the smallest degree bit by bit.

Grand Tutor Cao shook his head: "I can't faint, I just don't know if I can see clearly."

Without Li Wenchong speaking, Grand Tutor Cao consciously picked up a small-character book and read it.

It's still a bit difficult and can't see clearly.

So Li Wenchong replaced Grand Tutor Cao's No. 2 reading glasses.

When Grand Tutor Cao found that No. 2 reading glasses are clearer than No. 1, he gradually became interested and changed to No. 3 and No. 4. Unexpectedly, when he first changed to No. 4, he could see clearly?!

Oh My God?!

These reading glasses are really useful?!

The surprise was very good, so I quickly took the number 5 again.

It seems to be almost the same, and I want to get number 6 again.

Li Wenchong did not stop him and smiled and looked at Taifu Cao's Taifu for trial: "Teacher Cao, didn't you just say that No. 4 was already very clear? If No. 4 was clear, you should use No. 4. Although No. 5 and No. 6 were also clear, the larger the number, the greater the degree, the greater the impact on the eyes. It is best to use the smallest number, so that the burden on the eyes is smaller and it can be easier... This is like taking medicine, the medicine that can work with the minimum dosage is the best."
