Zhao Yuanjing heard it and looked over curiously.
He didn't care much about the glass workshop, only to give her a small business to toss about.
He still cares about arsenals, land and merchant ships.
Unexpectedly, in just a few months, she made a big profit of one hundred thousand taels.
This cannot be said to be a small business.
Zhao Yuanjing became curious about what she was tossing about.
Yundai opened the box and took out a pair of transparent...glass from the inside.
"What is this?" Zhao Yuanjing took it over and looked at it. There were two round lenses and a weird thin frame.
"These are called glasses." Yun Dai took the glasses and put them on the bridge of her nose. "That's how they are used."
Zhao Yuanjing looked at her and said with a smile: "So weird, what is it for?"
"For people with bad eyes." Yun Dai said, "The emperor has seen people who can't see things clearly when they are far away?"
"Yes." Zhao Yuanjing thought for a while, "When Jun Wang was young, his eyes were magical, and he couldn't see the person on the other side clearly. His son was eight years old, and he was in the same situation."
"This is called myopia. His son probably inherited him." Yun Dai smiled, "Look at this lens, there is a thickness in the middle, which is actually an imitated magnifying glass. It can magnify things in the distance so that the eyes can see clearly. ."
"So amazing?"
Zhao Yuanjing took it over, "Let me see."
Yun Dai took off the glasses and put them on his eyes.
Zhao Yuanjing looked at her and frowned: "It feels dizzy for a while."
Yun Dai chuckled and said, "This shows that your eyesight is very good, and you are not nearsighted."
Zhao Yuanjing hurriedly took off his glasses and said, "So, if this mirror is worn by King Jin, he can see clearly? In your shop, how much does it cost?"
"Range from ten taels to five hundred taels."
"...So expensive?"
"It's not expensive at all. Everyone has a different degree of myopia. These are all customized according to each person's situation." Yundai explained, "This is all hand-polished, and it takes a lot of time to make a pair. Naturally expensive."
"Then why are some worth ten taels, but some sell five hundred taels?"
"The materials are good, the appearance is good, and the packaging box is expensive." Yun Dai said.
"This sells for more than fifty times the price?" Zhao Yuanjing shook his head, "Since the functions are the same, why do people choose expensive ones."
"The emperor, you don't understand." Yun Dai took away his glasses. "This is called taste. There are so many rich people in Da Zhou."
"Why do you have money to buy this?"
"Follow the trend, compare it."
"Who's the wind with?"
"The emperor." Yun Dai opened another box and took out a pair of gold-rimmed glasses. "Look, this is a frame made of pure gold, which can definitely highlight the emperor's high-level taste. As long as you bring it, you can give it to the courtier. Let’s take a look and someone will follow suit.”
Zhao Yuanjing raised his eyebrows: "Give it to me? My eyes are so good that I don't need this."
"This pair is not myopia glasses, it's a flat lens."
Yundai unfolded his glasses, put them on for him, looked at it for a moment, nodded, "Sven scum, I like it."
Zhao Yuanjing blinked: "Not dizzy."
"That's natural." Yun Dai smiled, "This is for decoration. I also want to sell sunshade mirrors. Of course, I don't have this technology yet, and it's still under development. I will sell myopia, reading glasses and flat glasses first. ."
Zhao Yuanjing took off the glasses and asked, "How much does this pair cost?"
