Datang: The prince of salted fish was overheard by Li Er

Li You also made it very clear about the use of presbyopic glasses. He only uses them when looking at nearby documents, and does not need to wear them in normal life.

As a result, Li Jing naturally didn't wear it when he was in the court meeting.

After the Great Court Meeting ended, Li Jing and others followed Li Shimin to the Hall of Qinzheng.

As soon as he arrived at the Hall of Qinzheng, Li Shimin took out the latest local newspaper and asked about the current situation in the twelve northern states.

When it came to the specific situation, Li Jing became more cautious, and naturally put on his glasses after receiving the report.

This action quickly aroused the curiosity of others.

"Duke Wei, what is that on your head?"

Hearing Li Shimin's question, Li Jing quickly raised his head and replied, "Return to Your Majesty, the ones I wear are called glasses..."

Then Li Jing told him what Li You said when he went to the medical examination center.

After listening, all the people present were shocked, and then they all looked very curiously at the glasses on Li Jing's head.

Of course, Li Shimin is the most curious one among them: "This kid, Youer, has a lot of new ideas."

"Duke Wei, can you bring the glasses up for me to try!"

The most famous diligent emperor, Li Shimin has reviewed many memorials in recent years, and his eyesight has also deteriorated very badly.

In the early years, he was also able to count as a sharpshooter who could point to where to hit within a hundred steps, but now his eyesight is getting weaker and weaker.

After hearing Li Jing's praise, he was naturally even more curious, and immediately prepared to give it a try.

Naturally, Li Jing would not refuse Li Shimin's request, so he immediately took off the glasses and handed them over.

Holding the glasses in his hands, Li Shimin first looked at them carefully, and then put them on his head like Li Jing did just now.

However, as Li Jing said just now, the feeling of being refreshed and refreshed did not appear.

Instead, there was a strong sense of dizziness.

Fortunately, Li Shimin was sitting on the dragon chair at this time. If he stood up, he might fall down.

Li Shimin suppressed the nausea in his heart, immediately took off the glasses, and then asked in great puzzlement: "The effect that Duke Wei just said really exists?"

Li Shimin's pale lips were obviously not pretending, and Li Jing was also stunned on the spot for a while.

"Your Majesty, I don't know why this happened!"

Of course Li Jing didn't know, he couldn't see things nearby because he was old and had presbyopia, while Li Shimin's eyesight decreased due to myopia caused by overuse of eyes.

Not only are the causes of the two different, but the symptoms and treatment options are also very different. Taking glasses as an example, Li Jing uses convex lenses, while Li Shimin uses concave lenses.

At this time, Changsun Wuji, who was already relatively close to Li Shimin, walked over, picked up his eyes and tried it.

After putting on the glasses, Changsun Wuji's eyes immediately brightened.

"Your Majesty, these glasses are really a fetish. I can see things near me clearly again!"

"What Duke Wei said is true!"

As soon as this remark came out, the Palace of Qinzheng exploded again!
The same glasses, worn by different people, will have completely different effects, which makes all the ministers present in a state of confusion.

At this time, it was Li Shimin who saw that there must be something strange in it, so he said: "Everyone, don't panic, come and try these glasses and see what it feels like."

Following Li Shimin's instructions, Fang Xuanling, Du Ruhui, Li Junxian, Wei Zheng, Wang Gui, Wei Ting and others put on their glasses one by one.

Sure enough, after some experiments, Li Shimin quickly found out the pattern.

People with good eyesight in the crowd, such as Li Junxian, although he also felt dizzy after wearing it, the condition was not serious.

Du Ruhui and Li Shimin, who were relatively young in the crowd, had similar reactions, and they were the most uncomfortable.

The ones with the best effect are Changsun Wuji and Fang Xuanling, who are about the same age as Li Jing. Basically, wearing glasses can completely solve their vision problems.

On the other hand, the older ones, especially Wang Gui, could see a little more clearly after wearing glasses, but they were still a bit blurry.

"It seems that these glasses are for older people."

"And it seems that these glasses are only suitable for people of Duke Wei's age."

Li Shimin quickly came to a conclusion.

It was Li Jing who also remembered what Li You said to him at that time, and continued: "Your Majesty, King Yan also said about your current situation at that time, but I forgot just now."

"However, King Yan also said that glasses vary from person to person and require special optometry and customization. Qi Guogong and Master Wei are about the same age as me, so the condition of their eyes is probably similar, so they are suitable for me."

Hearing Li Jing's words, everyone present was a little eager to try, planning to go to the physical examination center of Shence Mansion after returning today.

The physical condition is still secondary, but I need a pair of these glasses.

Nowadays, as the national power of the Tang Dynasty grows stronger and its territory becomes wider and wider, there are more and more official documents to be processed, and they often read newspapers all night long.

In this era, oil lamps and candles are used for lighting at night, and the brightness is not enough, and the light will vibrate when there is wind. Under such harsh conditions, many people's eyes can't bear it.

In fact, not only the other ministers, Li Shimin was also a little moved at this time.

After seeing everyone's expressions, Li Shimin waved his hand and said: "Since all the lovers are in need, there is nothing urgent about today, why don't you follow me to the Shence Mansion for a walk."

Li Shimin's proposal was immediately echoed by everyone, and then a mighty team set off for Shence Mansion.

Not long after the team left Miyagi, Li You, who was still "sleeping" in the palace, saw the news of Jin Yiwei.

"What's the situation! Li Er is going to the Shence Mansion with a group of ministers!"

"What are they going to do! Is the news accurate?"

Facing Li You's series of questions, Yu Huatian just nodded firmly and said, "I don't know why His Majesty is leaving the palace yet, but it is certain that I will go to the Shence Mansion."

"Besides, the guards of the Yellow Gate have also come to pass the order to the Wangfu, and they should have invited the prince to pick him up!"

Regarding Yuhuatian's answer, Li You didn't know what to say except MMP, so he could only ask Sakura to change his clothes, while constantly recalling what he did in the past few days that caused such a big sensation.

Until Li You received the imperial decree brought by the guards of the Yellow Gate, he still hadn't figured out what it was for.

In the end, it was Sakura's words that woke Li You up.

"Your Majesty, your Majesty and the others are going to the medical examination center of Shence Mansion this time. Could it be because Wei Guogong came for the physical examination before?"

Speaking of which, since the opening of this medical examination center, it has not seriously promoted it. Apart from the officials from the Ministry of Household Affairs, the biggest official it has received is Li Jing.

But this time Li Shimin suddenly wanted to come to the medical examination center, it was very likely that it had something to do with Li Jing.

Thinking of this, a smile finally appeared on Li You's face, and the anxious movements just now slowed down.

"My lord, what is your Majesty's visit this time?"

Facing Xiaoying's question, Li You chuckled and said, "What else can I do, don't you think we don't have enough funds, so give us some money!"
