On the other side, Ying Feiyu was sent to draw a vision measurement chart.
This thing is not difficult. Just find a standard vision measurement chart on the system, cut out the appropriate paper according to the size standard, and draw it!
However, I think that just measuring is not enough, you also have to find suitable lenses and actually test them, otherwise you will still get dizzy after taking off your glasses!
For example, the measured degree is 300 degrees of myopia. However, if the degree is enough, you will definitely feel dizzy when wearing it, and you will not even be able to walk well.
Therefore, Ying Feiyu planned to grind out some lenses with different powers and let Ying Zheng try them on himself to find the most acceptable power within the suitable range of vision!
Moreover, after this thing is built, it can be used repeatedly.
It will also be useful when giving glasses to ministers in the future!
So we drove to the glass factory!
"How can this machine be so useful?"
"Why have you never heard of the emperor's younger brother mentioning it before? You built the thing quietly?"
Before Ying Feiyu entered the workshop where the edger was placed, he heard a commotion inside, and it seemed that a lot of people had gathered.
The voices coming out sounded like those of Huang Yuan and Ying Heng!
After stepping in, you will find a room full of craftsmen.
"Your Majesty? The common people see your Majesty...!"
After seeing Ying Feiyu, he was stunned for a moment, then quickly said hello and allowed a passage to come out.
"Your Majesty? You are here too!"
"Royal brother, we are trying to tease you!"
Huang Yuan also quickly handed over his hand, while Ying Heng came over with a smile.
"I haven't asked you yet. This machine was just moved here yesterday, and you guys have already arrived today. The information is too well-informed!"
Ying Feiyu put his hands behind his back and said with a smile.
About the glasses, only the father, the mother, and the maids in the Yuxiu Palace knew about it in the entire palace.
Outside the palace, only the employees of the glass factory knew that Huang Yuan and Ying Heng brought people over today, and they were really fast!
"Haha! Your Majesty, are you afraid that you have forgotten the relationship between your subordinate and the director of the glass factory?"
Huang Yuan raised the corners of his mouth, showing a sly smile, and nuzzled his lips at his nephew.
Ying Feiyu slapped his forehead in annoyance, "Hey! Look at my memory. This is your nephew. If there is something new, I will definitely notify you as soon as possible!"
"Yes! After the official got the news, he thought that Young Master Heng would also be very interested in electrical appliances, so he dragged him along!"
Huang Yuan took the initiative to admit it.
"Royal brother, you are not interesting enough! You are producing such an important machine and you didn't reveal any information to us in advance!"
Ying Heng had a sullen face, pretending to be angry.
"It's not that I don't want to disclose it, but you all have too many things to do. I can't always be the boss and push everything onto you, right?"
Thinking that sooner or later they would receive the news and come over, Ying Feiyu thought of an excuse early in the morning.
"The emperor's brother has to manage the entire Qin Dynasty, and there are many matters in the government that need to be dealt with, but it is much harder than us!"
Yingheng is very interested in these things. Even if there are many things at hand, he must persist in research and manufacturing.
"Haha! Okay, you have already seen the machine, and you must know what it does. You will lead people to study it later, set up a production line, and mass-produce it!"
Ying Feiyu smiled and nodded.
"Don't worry, Emperor Brother. I will study with Huang Yuan later and try to get the production line up in the shortest possible time!"
Ying Heng had already come over early in the morning. After understanding the function of the machine, he studied its working principle and discussed it with Huang Yuan.
By now, we have roughly understood its working principle, and we are just waiting for Ying Feiyu to order them to dismantle it to see the internal structure and start the production line!
"good!"
The two of them were so motivated that it saved Ying Feiyu the need to go find them personally.
"Your Majesty, you came here today, but what is the important matter?"
After talking about the machine, Huang Zimo was finally able to add a word.
When Ying Feiyu left yesterday, he taught them how to grind lenses and let the craftsmen practice. He thought that His Majesty was here to accept their practice results!
"I plan to make an optometry test stand and some inserts with corresponding degrees!"
Huang Zimo and the craftsmen had some understanding of myopia and reading glasses before, but they were still very unfamiliar with the words Ying Feiyu said this time.
Looking at their expressions, Ying Feiyu understood and explained with a smile, "To put it bluntly, the insert is a separate lens with a prescription. It does not need to be embedded in the frame of the glasses, but it must have a small handle to facilitate the removal from the audition. Plug and unplug on the frame! And the audition frame is a frame that can be inserted with many inserts of different degrees at the same time!”
"For example, if my glasses are 300 degrees, I can use lenses of 200 degrees, 50 degrees, 30 degrees and 10 degrees to increase the test until I find the right degree!"
"Usually, the power of two eyes of a person is not the same, so both eyes must be tested!"
"When wearing glasses for the first time, if you choose too high a power, it may cause dizziness, which may lead to danger...!"
Ying Feiyu briefly explained the use of the audition stand and inserts.
Huang Zimo and the craftsmen nodded again and again, understanding, "His Majesty is still thoughtful!"
"I have a blueprint here. You can follow the blueprint and find suitable materials to make it. I will take it back to the palace later to measure your father's prescription and get a more suitable pair of glasses!"
"yes!"
Huang Zimo took the drawing and went to do it immediately.
With yesterday's experience, it will be much easier to recreate the frame today.
"In addition to researching machines and running production lines, I have other tasks for you!"
After Huang Zimo left, Ying Feiyu looked at Huang Yuan and Ying Heng again.
"That's what His Majesty ordered!"
"Yes, my dear brother, just tell me if you have anything to do!"
The two raised their ears and listened carefully.
"It's easy to say that the lenses can be made of high-quality glass! But the material of the frame still needs to be studied. It must not only be tough and not easy to break, but also light enough so that you won't feel uncomfortable even if you wear it all day long! At the same time, it must also be beautiful. , and divided into three, six or nine grades!"
In later generations, there were many different materials for lenses.
Glass, resin, PC, nylon, etc.
But in this era, many materials cannot be made, the only choice is glass!
Crystal can also be polished into lenses, but the cost is too expensive and cannot be afforded by ordinary people!
Before other lens materials are developed, Ying Feiyu plans to differentiate between high and low prices on frames.
"good!"
Huang Yuan immediately nodded and agreed.
"Brother Emperor, how is the production of your phone going?"
After explaining these things, before Huang Zimo came back, Ying Feiyu asked about other progress.
"It's going on smoothly and it won't take long for it to be offline!"
In order to allow the people of Daqin to use telephones as soon as possible, after the electrical appliance factory was built, Yingheng immediately arranged a large number of craftsmen to work in three shifts for non-stop production day and night.
"Where are you?"
If you want to make a call, you don't need a telephone, you also need to pull up the telephone line.
"Your Majesty, after aluminum became available, the production of telephone lines was very fast. I have sent people to pull up a main line in each county! After the telephone is built, whoever wants to install it just needs to pull out a branch. Can!"
Huang Yuan handed over his hand to report the progress.
"okay!"
Ying Feiyu was very satisfied with this and nodded repeatedly.
