Su Mo tilted her head and smiled at him, beckoned him over, and said to several gray-haired old craftsmen: "Master Yu, Master Zhou, Master Jing, actually these glasses existed a long time ago. They are made of crystal and topaz.
When the gems are polished, they can be magnified like looking at objects through water. When people reach a certain age, they will have presbyopia, so if you wear one, you can see clearly."
The chubby-faced Master Yu said with a smile: "In this case, when we wait for another two years, we won't be afraid of being dazzled."
For these craftsmen who rely on their craftsmanship, it is their hands and eyes.
When you reach a certain age, you can no longer see clearly, so you can only teach your sons and apprentices. However, if your eyesight is not good, teaching will also be affected.
If you have what the little boss said, wouldn't you be able to live for a lifetime?
They were really excited, and several people chattered, "The boss told us the secret recipe for burning glass. It's not as difficult as we thought. The cost of this glass is definitely cheaper than gems. The boss sold the glass and converted it into gold."
Silver, that’s a bargain.”
The thin Master Di Jing clapped his hands and said: "Yes, yes, let's make these glasses and other things, and let the owner sell them in Beijing. Look at the variety of things the owner has said, some are good-looking ones, and some are good-looking ones.
There are those who are presbyopic, and there are young people who are presbyopic, and there are also those who cover the sun. Those dignitaries are very ostentatious, and they must be willing to spend a lot of money."
Several masters discussed it and just went ahead. One was responsible for finding ready-made glass to study, and the other was responsible for drawing graphics to see if they could be re-blown to meet the requirements, and they got busy.
Although Huangfu Jin heard it mysteriously, he also understood that presbyopia in young people turns out to be called myopia.
He has gained a lot of experience.
He stared at her, wondering how much this little woman had in her head.
He knew that the precious mirror was useful for reading and magnifying, but it was not very useful.
There are two Zhenlong Pavilions in the palace.
That's something that has been passed down from generation to generation.
How did she know?

Ancient people were very powerful and smart, so this is just a fiction. Hey, reading glasses and myopia glasses have been around for a long time in ancient times. There are also convex lenses. Use mirrors to make fire.
