Yan Shiyue originally thought that it was time to get glasses after seeing the glass window.
Glasses are a necessity and were already part of her plan.
When she first made glass, the craftsman needed training, and she herself didn't have her hands free, so she just made a magnifying glass as a last resort. Now, after three years of fermentation, she should be able to start making delicate things.
The only thing she was familiar with was the E table; she was not familiar with the C table or anything else.
Under normal circumstances, the naked eye can distinguish the visual angle formed by the minimum distance between two points, which is a one-point visual angle. The three-stroke E is of equal length, and each stroke, as well as the space in the middle, is one-fifth of a square, so it is more in line with the design meaning of visual angle resolution.
So whether it is the eye chart for myopia or the eye chart for presbyopia, she plans to use the E chart. At worst, she won't mention letters or anything, and just think of it as a graph.
The size and spacing of each letter in the eye chart have fixed standards. For example, the side length of the first line is 7.27mm, and the ratios below it are 1:1.5:2:3:4:5... and so on.
So just making an eye chart is very troublesome.
Besides, eye problems are not trivial matters. They cannot be approximate. They must be precise, and we need to develop a set of eyeglass fitting equipment that is as sophisticated as possible.
Although she drew the blueprint and asked the craftsmen to do it, drawing the blueprint is also very time-consuming!
...
...
The key is that there are so many children!
She was very popular, and a group of them would come running over at any time, with their innocent and cute little faces looking up, blinking their bright black grape eyes, and speaking in baby voices. She was reluctant to refuse them, and she would waste an hour or two by the delay.
Besides, Huo Qijing is not here yet, so no one can replace her.
Huo Qijing has been very busy in the past few months, running back and forth every day, and he has become darker and thinner. When he occasionally comes back, she is reluctant to use him and wants him to sleep more. He has sharp ears, so she even keeps the child away from her.
She complained to Meng Min privately more than once: "If I had known I wouldn't have given birth to so many kittens, I guess I wouldn't be able to do anything at home when these four kittens grow up."
Meng Min smiled and said, "You have a lot of things to do. When you grow up, send you to my place. I get bored all day long and I just love watching the kids make noise."
The Queen also laughed and said, "You listened to her and didn't let her see him, but she missed him again! I don't know where this bad habit came from, she gets tired of playing with the child for a while, and when she can't see him for a while, she comes looking for him again."
Biological mother.
Yan Shiyue could only step back silently.
When drawing such a detailed picture, the light from candles is not enough and it hurts the eyes.
She was forced to shorten her sleeping time, and even gave up her last attempt to sleep in... She got up at dawn and started working. Finally, she managed to send the map back to the capital before leaving the palace, so that she could start working on the lenses after she returned.
Even Emperor Mingyan laughed and said, "It seems that being a mother is different. In front of me, she acted like a spoiled brat and refused to attend the morning court. But now, she wakes up earlier than the morning court!"
Yan Shiyue: “…”
This life is really unbearable!
In fact, she has always been quite delicate. Usually, after finishing something important, she has to sleep for a day and a night, or two days and a night.
As a result, this time, Zhou Jianwei came looking for him right after he returned to Chang'an City.
The eye chart was easy to deal with, but he himself couldn't understand these devices, so it was difficult for him to explain them to the craftsmen.
So Yan Shiyue was called to the Ministry of Commerce as soon as he entered the Duke's Mansion without even changing his clothes.
On the other side, Emperor Ming Yan and his entourage entered the palace.
The Queen Mother hadn't seen the Ninth and Tenth Princes for several months, and she was worried about them, so she sent Nanny Fu over early to bring the Ninth and Tenth Princes over.
When the two children came in, the Queen Mother opened her arms with joy: "My dears! Come to my side!"
As a result, the ninetieth prince came up to her and saluted neatly: "Greetings, Grandmother."
Whenever a child learns something, he loves to show off. These days in the palace, he would bow whenever he saw Emperor Mingyan and the Empress. The two of them thought it was a good thing and praised them repeatedly, so they paid more attention to it. Each of them bowed properly and beautifully.
The Queen Mother had never seen them perform a salute before, and was stunned. After she came to her senses, she said anxiously, "Oh my! My dearest child, why are you performing a salute? Come quickly and ask the Imperial Grandmother to take a look!"
The two of them then came over.
Children are actually very forgetful. I haven't seen her for a few months. These few months were very colorful and I learned a lot. But when I saw the Queen Mother again, I felt a little strange.
The Queen Mother saw this and almost burst into tears. She stroked the two men's faces back and forth and said, "What's wrong? Why are you being so distant with the Imperial Grandmother? Come on, tell the Imperial Grandmother, is there anyone bullying our Jiulang and Shilang?"
The Ninth Prince shook his head: "No one bullies me."
The Queen Mother asked, "Then tell the Imperial Grandmother what you did when you went to the temporary palace?"
When they heard this, the two children were very excited. One of them said, "Sister Royal, tell us a story!"
That one said, "He also taught us Kung Fu!"
“And he taught us how to write!”
“Teach us how to grow vegetables!”
"Loosen the soil! I dare to catch bugs!"
"I dare to do that! I dare to do that! I can even wash the vegetables!"
The two little ones were excited and spoke one after another.
For them, growing vegetables with their father is naturally much more fun and novel than writing and reading, and the memories are more profound.
The Queen Mother responded repeatedly: "Okay, okay, you are so good! Tell the Imperial Grandmother if you miss her."
If this was a child who grew up in adversity, he would know what to say at this moment without even thinking, but Jiu and Shi had been spoiled since childhood, and the concept of pleasing others was simply not in their minds, so they shook their heads very honestly.
The Queen Mother's expression was a little strange, and she laughed and scolded: "What a heartless little thing!"
Jiulang immediately said, "You have no conscience. This is insulting! The Queen said that we cannot speak village dialect!"
"Yes!" Juro shared the same hatred for the enemy: "It's wrong to speak in the village language! Juro doesn't want to talk to you anymore! You will learn bad things!"
Aunt Fu was standing nearby and she wanted to hold her forehead with her hand when she heard this.
Stop talking, little ancestors. Your royal sister is almost being tricked to death by you!
But the Queen Mother was already angry.
He said calmly: "Take them down to play on the slide for a while!"
"No, we don't want to play on the slide!" Jiulang Julang said, "It's time to listen to a story! The royal sister said that we need to have a plan when doing things!"
So the two of them bowed and ran out.
Nanny Fu secretly glanced at the Empress Dowager's expression.
The Queen Mother looked gloomy.
Shou Ma's eyes moved slightly, she stepped forward to refill the cup of tea, waved her hand and asked the palace servant to leave, and advised: "Empress Dowager, please don't be angry, forgive me for speaking frankly... After all, the little prince grew up in the countryside, and he has a naive temper. It is inevitable that he takes Jiulang and Shilang to grow vegetables."
The Queen Mother said angrily, "This is my grandson! A prince! Born to be a superior person! Learning to till the soil! Learning to grow vegetables! These things that bring disaster to the children, what is the point of learning them! Look at what I have done to my well-raised child! Each one is like a wooden man, bowing as soon as he enters the door! I am their grandmother, why should they be so particular about etiquette! How many people in this world can make them bow?"
Shou Ma Ma hurriedly advised: "Your Majesty, you are right. The little prince is still very young and doesn't think so much... Besides, the little prince has many errands to do. Looking at the Qi Lang Ba Lang back then, we know that the little prince is not a person who has the patience to coax a child..."
The Queen Mother became even angrier: "With her violent temper and the Emperor's pampering, she would never do such a thing! She must have been thrown to the subordinates at random. What can a bunch of slaves teach them? What dare they teach them! Isn't it just teaching them how to behave to please us?"
