254 Presbyopia Glasses
At this time, Grandpa Bai said, "There is a solution. In your previous world, presbyopia and myopia were very common, especially myopia. They would go to the optical shop and wear a pair of glasses. After putting them on, they could see clearly."
After being reminded by Grandpa Bai, Zhao Zhitong remembered that a neighbor’s older sister in her previous life wore a pair of glasses. She had thought that sister looked so good with glasses and had even wanted to try them on to look pretty.
However, the neighbor’s sister scared her, saying she couldn’t wear them, or her eyes would get damaged. This frightened her off.
At this thought, Zhao Zhitong’s eyes brightened. That’s right! I can buy a pair of presbyopia glasses for Yunniang! Then she’ll be able to see clearly.
Once she made up her mind, Zhao Zhitong’s consciousness entered the space and went to the market window. "Grandpa Bai, are there any presbyopia glasses for sale in the market?"
Grandpa Bai nodded with pride. "Of course! In my market, your Grandpa Bai’s market, there’s nothing you can’t think of and nothing you can’t buy."
While he was speaking, he opened the market and adjusted it to the presbyopia glasses page. Various types of presbyopia glasses instantly appeared in the window.
There were black plastic frames, individual magnifying glasses, metal frames, and even foldable ones that could become very small.
Looking at all these options, Zhao Zhitong felt overwhelmed. "There are so many kinds! Which one should I buy for Grandmother?"
Grandpa Bai reminded her, "Young girl, presbyopia glasses also have degrees."
Zhao Zhitong was surprised. "Oh? I don’t know what degree Grandmother needs. How do I buy them?"
Grandpa Bai explained, "The level of presbyopia changes with age, so the degree of the glasses will also deepen accordingly."
"In your previous world, some elderly people in rural areas didn’t know to go to specialized optical shops to get prescription glasses. Most of them used their age range as a guide and bought presbyopia glasses directly at the marketplace."
"Generally speaking, people aged 40 to 45 might need glasses with a degree of around 100 to 150, while people around 50 years old might need 200-degree glasses, and those around 60 years old might require about 300-degree glasses. Beyond 60, the degree doesn’t change much."
After listening to Grandpa Bai’s explanation, Zhao Zhitong pursed her lips and said, "Grandmother is 46 years old this year, so I’ll choose 150-degree glasses for her."
Grandpa Bai nodded.
Zhao Zhitong saw that a pair of glasses didn’t require many Merit Points; one pair could be exchanged for about 50 Merit Points.
After completing the exchange, Zhao Zhitong exited the space.
She chose a pair of iron-framed presbyopia glasses because the iron frames were easier to explain than the plastic ones.
Zhao Zhitong examined the presbyopia glasses, turning them over in her hands. Then, she briefly held them in front of her eyes. Instantly, it felt as if a large pit had appeared in the ground. Her head spun, and she quickly took them off. "Whoa, so dizzy!"
At this moment, Zhao Ya came over and saw Zhao Zhitong holding an odd-looking object up to her eyes. Curiously, she asked, "Little Sister, what’s that thing you’re holding?"
Zhao Zhitong proudly introduced, "These are called presbyopia glasses. They can help Yunniang’s presbyopia."
Zhao Ya listened with confusion. "Presbyopia glasses? Presbyopia? What’s that? Is it the name of the illness Master has?"
Zhao Zhitong didn’t explain to Zhao Ya but simply said, "Anyway, as long as Grandmother wears these glasses, she’ll be able to thread needles again."
Hearing this, Zhao Ya’s eyes lit up, and she exclaimed, "Really?"
Her master had been unable to embroider for a long time, so she had always relied on her master’s verbal instructions, which sometimes meant she made mistakes.
If Master’s eyesight improved, that would be wonderful!
Zhao Zhitong nodded firmly. "Of course! Would I lie to you?"
Zhao Ya smiled shyly. Yes, Little Sister would never lie.
Then Zhao Zhitong showed the presbyopia glasses to Zhao Ya. "Look, it’s so interesting! When you put them in front of your eyes, a big pit appears on the ground in front of you!"
Zhao Ya skeptically took the glasses and held them to her eyes. She then exclaimed, "Wow, it’s true! There really is a big pit in the ground! I’m so dizzy!"
She took off the glasses to look at the ground again, and it returned to normal. Putting the glasses back in front of her eyes, the big pit reappeared. "It’s gone! Oh, it’s back again! Wow, it’s gone again!"
Zhao Zhitong said gleefully, "Right, right? Isn’t it really fun? HA HA HA."
Zhao Ya nodded. "Mhm, mhm, very fun!"
The two little girls played with the presbyopia glasses, looking back and forth like this for a while.
Then Zhao Ya asked curiously, "If these make us feel so dizzy, will Master be able to see clearly when she wears them?"
Zhao Zhitong nodded, recalling the information Grandpa Bai had shared with her. "Yes, of course. Grandmother’s eyes—well, our dark eyeballs have something called the crystalline lens. As one ages, it gradually hardens and thickens."
"The eye muscles that adjust for focusing near and far also become less flexible. This causes... um... it causes the focus for things up close to land on the... canvas... I mean, to land behind the eye. That’s why she can’t see things up close clearly. Wearing these glasses will help her see clearly again."
Zhao Zhitong explained a lot. Zhao Ya understood each individual word, but when they were all put together, she couldn’t make sense of it at all.
Her head was full of question marks, but she just gazed at Zhao Zhitong with starry eyes. "Little Sister, you’re so amazing! You know so much!"
Zhao Zhitong’s little face flushed red, and she laughed happily. "Then let’s go give them to Grandmother."
Zhao Ya nodded. "Okay, Master will definitely be happy."
The two little girls held hands and ran to Yunniang’s room.
When they arrived, Yunniang was holding a needle and thread, holding it up close and squinting as she tried to thread it. Hearing the commotion, she put the needle down and looked up to see Zhao Zhitong and Zhao Ya, panting from their run.
Yunniang smiled and asked, "Why are you two running so fast?"
Zhao Ya quickly ran over and hugged Yunniang’s arm, saying excitedly, "Master, Master, Little Sister found a way to treat your eyes!"
Yunniang was startled.
Zhao Zhitong had already taken out the presbyopia glasses and handed them to Yunniang. "Grandmother, try them on."
Looking at the glasses in Zhao Zhitong’s hand, Yunniang’s pupils widened slightly. Firstly, she was excited at the prospect of her eyes being able to see clearly again. Secondly, She could tell at a glance that this thing in Zhao Zhitong’s hand was definitely not cheap!
This crystal-clear, light-permeable thing... it couldn’t be the fabled liuli glass, could it?!
While Yunniang was in a daze, Zhao Zhitong placed the presbyopia glasses in her hand, urging, "Grandmother, quickly put them on and see."
Yunniang hesitated. "This... this..."
Zhao Ya also urged, "Master, quickly put them on and see if you can see clearly."
Yunniang had no choice but to put the glasses on her face. Then, she looked at her own palm, her eyes widening in amazement as she exclaimed, "I can really see clearly! I can see the lines on my hand so very clearly!"
Hearing this, Zhao Zhitong and Zhao Ya both cheered happily.
Then Yunniang, almost compelled by the sudden clarity, picked up her needle and thread again. This time, unlike in the past when she would struggle for ages, she threaded it easily.
Seeing that she could thread a needle once more, Yunniang was thrilled. However, after the initial rush of joy, she composed herself.
