Transmigrated into a female county magistrate during a famine, leading her country to prosperity

Chapter 728 Vision Optometry

Li Shiyuan had long thought that Shen Zheng would give the credit to him.

Therefore, when he was still in Xingning Prefecture, he reported all the truth to Yu Jiusi word for word.

"Sir Shen." He put down his chopsticks and looked at Shen Zheng seriously. "Without you, there would be no old man today. There is no such thing as stealing credit between you and me. What I said to General Yu is also the truth. So how much credit we share between you and me, I guess... it depends on your majesty's decision."

Shen Zheng sighed slightly.

Eventually, the news reached the capital again, but fortunately it was just a vaccine, not the entire "Yaowangji".

Ever since she gave "Medicine King Collection" to Li Shiyuan, she never thought of competing with Li Shiyuan for credit.

Whether it was the smallpox vaccine or the lost acupuncture technique, it didn’t matter to her who got the credit.

As long as the people can live a good life, that is enough.

After dinner, Shen Zheng discussed the clinic matters with Li Shiyuan.

In the near future, Li Shiyuan will become famous, and Tongan Medical Clinics will flourish all over the Great Zhou. There are some things that should be paid attention to.

"The National Medical Bureau is directly under His Majesty, we can be good friends." Shen Zheng talked about His Majesty's reform of the National Medical Bureau, and then said: "Tong'an Medical Clinic has also caught His Majesty's eye. As the head of the clinic, you must be careful in your words and deeds in the future to avoid making mistakes. If my guess is correct, after the Liuyang Prefecture branch is established, officials from the bureau will come to the county, and then..."

"Being neither humble nor arrogant and treating others with sincerity is our code of conduct," said Shen Zheng.

The implication is - there is no need to be flattering, there is no need to be afraid, just be sincere, don't embarrass the other party, and don't be afraid of the other party causing trouble.

"You two have worked hard along the way. Go back and rest after dinner." Shen Zheng stood up and said with a smile, "I have something else to do, so I'll leave first. Oh, by the way, Doctor Li, after you've finished your work and rested, remember to come to the printing house to find me. Let's discuss the details of the establishment of the branch clinic in detail."

In the future, the number of people who "join" the clinic will only increase, not decrease.

How many of them came truly for the people, and how many came just for the name of Tongan County?

None of it is known.

So they have to do a good job of screening from the very beginning.

To safeguard the reputation of Tongan County is also to safeguard the people.

......

Two days later, printing house.

The new blast furnace room is already under construction, and the days that Shen Zheng and others stay here to work are quietly entering a countdown.

Cicadas chirped non-stop overhead. Shen Zheng rubbed the glass back and forth to the rhythm of the cicadas, causing sweat to form on his forehead.

Old Qiao came out from outside the printing house, and Cheng Yu followed behind him, holding a half-big box in his arms. As he walked, the items in the box made a clanging sound.

"pat-"

The box fell to the ground, raising a thin layer of dust. Old Qiao opened the lid and showed it to the public, "The things you want are ready."

Shen Zheng looked up in surprise: "It's done already? You're so fast! I'm so surprised!"

The corners of Qiao Lao's mouth dropped, and he muttered, "Why are you imitating the old man... Come and see if it is what you want. If not, I will change it."

After saying that, Cheng Yu gently placed all the items in the box on the table.

Shen Zheng's eyes became brighter and brighter. She picked up the items and introduced them one by one: "Trial glasses frame, trial glasses clip, pupil distance meter, eye patch, eye chart! These are all useful for eye examination."

Liang Fu already knew what "eye test" meant, but the two old men Qiao were completely confused.

Old Qiao could only ask: "Then take a look, does this thing work?"

Shen Zheng touched them one by one, gave them a thumbs up, and praised them generously: "You are doing very well! Come on, let me test your eyesight, you can learn while testing, and test Uncle and the others tomorrow."

While they were still in a daze, they were unexpectedly given a difficult task.

Liang Fu was the most enthusiastic, his old bones standing straight, "How do you measure? I'll go first!"

Shen Zheng coughed lightly, "Our eye test lenses...are probably still in the furnace. So we can't test them right now. We can only look at the eye chart first. Once the lenses are ready, we can do a detailed test."

In recent days, there has been considerable progress in glass firing.

Nine out of ten furnaces can be successfully fired into molten glass.

Among the nine furnaces, two furnaces had low impurity content and high purity, and began to take on the appearance of optical glass.

Among these two furnaces, half of them can be finely annealed and formed, and finally become primary optical glass with extremely high purity and qualified stress.

Although this type of glass is not as transparent as synthetic resin, it has relatively high visibility and can still be made into lenses.

However...the story is not over after the optical glass is produced.

The first step, grinding the curved surface, is divided into coarse grinding and fine grinding, which is a very delicate job. The degree of the glasses is determined in this step.

After grinding, polishing is required. After polishing, the degree can be accurately calculated.

Let’s talk about “precision”… Actually, it can’t be too precise. After all, all the processes are purely handmade, and it is difficult to achieve the precision of electronic machinery.

But Shen Zheng still said the same thing - we have to take one step at a time.

The first generation of myopia glasses...as long as they work.

Shen Zheng knew that Liang Fu was farsighted, commonly known as "presbyopia", but she still followed the procedure and asked Liang Fu to stand five meters away from the eye chart.

The eye chart used the appearance style that Shen Zheng was already familiar with - a white background with a black pattern opening on one side, but there was no light through the bottom.

Shen Zheng stood beside the eye chart, holding a small wooden stick in her hand, tapping the top row of individual patterns, and asked with a smile, "Which way does it open?"

Liang Fu's eyes fell on the bottom of the small stick, and his expression gradually changed from excitement to confusion.

"Such a large pattern..." He pointed to the right and frowned, "Is it necessary to ask?"

Mr. Qiao and Cheng Yu nodded in agreement.

That pattern is almost as big as Lord Shen's fist, how could anyone not see it clearly? !

Shen Zheng held up the small wooden stick and said seriously, "Don't disbelieve me, there are really people who can't see clearly."

Then she pointed to a pattern in the middle and asked, "What about this one?"

The three of them said in unison without hesitation: "Up there!"

"Hey!" Shen Zheng pointed at the first one in the second to last row, "What about this one?"

Qiao Lao and Liang Fu: "Still up there!"

Shen Zheng squinted slightly to avoid the sun and looked at Cheng Yu who pursed his lips: "Can't see clearly?"

Cheng Yu moved his lips twice, hesitated for a moment, and then nodded: "It seems so... Starting from this row, it becomes blurry, and the whole small pattern seems to be stuck together, and I can't tell where the opening is."

Old Qiao slapped his thigh when he heard this, "I can see it clearly, how come you can't see it clearly?"

Cheng Yu's ears turned red and he almost buried his head in the ground.

He is so young, but his eyesight is not even as good as his master's?!
