Xueba's life simulator

Chapter 229 Myopia
In addition to a meeting between the main figures on both sides in May, Huaguo also promoted the development of a policy.

And in June, all parts of the country have also entered the examination period. The college entrance examination, high school entrance examination, English level four, etc. are all held in June.

After the college entrance examination, Uncle Zhou Ming's son, Zhou Ming's cousin Zhou Rui and Aunt Zhou Ming's daughter, his cousin Song Lina, ran to Luzhou to play like wild horses that had run loose. up.

If Zhou Ming was alone in Luzhou like before, Zhou Ming's uncle and aunt probably wouldn't let their children come to Luzhou to delay Zhou Ming.

After all, Zhou Ming's current identity and the relatives around Zhou Ming also know that he is usually busy in Luzhou alone. If his children come to Luzhou to trouble him, won't it delay his work?

In this world, not all relatives are like those shown on TV, ignorant and fond of messing around. Most relatives are quite normal.

After all, everyone hates such a person, but everyone is also a relative of others. May I ask if you are such a relative?
However, now that Zhou Ming's family has moved to Luzhou, and even Uncle Zhou Ming's family is planning to move here, even if Zhou Rui and Song Lina both come, Zhou Ming will not be troubled too much.

Zhou Ming used to do this kind of behavior of going to relatives' houses during the winter and summer vacations. It's just that after he went to university, he didn't go to relatives' houses during the winter and summer vacations like before.

In fact, the main reason why Zhou Ming went to play with his relatives during the winter and summer vacations was because the relatives had a computer at home, so he could use the computer to play when he was there.

So now that Song Lina and Zhou Rui came to Luzhou to play, it was quite normal for their family.

"Your aunt said that Lina wants to have myopia surgery. Is there anyone you know there? If there is, you can ask Lina to go to someone you know for this surgery."

In the evening, Zhou Ming's mother and Zhou Ming talked about Song Lina, but Zhou Ming's cousin hadn't come yet.

"Lena is short-sighted?"

After hearing what his mother said, Zhou Ming was a little surprised, because he had never seen his cousin wearing myopia glasses before, let alone heard her mention that she was nearsighted. He always thought that his cousin was not nearsighted like himself.

Another reason why Zhou Ming has such a point of view is that his cousin Zhou Rui is not short-sighted either.

Whether myopia or not, many people think that the root cause is bad eye habits. This is indeed a very important reason, but whether most people will get myopia actually depends on genes, and the heritability of myopia is as high as 0.9.

The heredity rate mentioned here does not mean that the parents are myopic, and the children are more likely to be myopic.

Rather, it is the ratio of the genetic variance and the phenotypic variance of myopia. The heritability of myopia is as high as 0.9, which means their ratio is 0.9.

No matter how much they waste their eyes, some people play computer, watch TV for a long time, or stay up late to check their mobile phones, but they are not short-sighted. This is a genetic problem.

Of course, even if you have the myopia gene, if you have good eye habits and do not have this predisposing factor, you will not have myopia.

The point to be mentioned here is that myopia is not controlled by a single gene.

As far as the current research is concerned, although there is correlation between parents and children, and non-identical siblings, the correlation number is far lower than that of identical twins.

According to the future knowledge in Zhou Ming's mind, even in the future, for a long time, people still haven't fully figured out which gene fragments are specifically related to myopia.

The reason for this situation is mainly because in the previous simulations, the future world will develop not only life science technology, but also artificial intelligence technology.

Due to the development of artificial intelligence technology and brain science technology, especially the development of cloning technology, the first thing many people think of after they get myopia is to simply replace it with a cloned eyeball, or even directly replace it with an electronic eyeball.

It stands to reason that no matter how small the eyeball is, it is still an organ, and it is also a "complete" organ with structures such as nerves, blood vessels, muscles, etc. There are too many problems that need to be overcome in order to achieve eyeball transplantation without sequelae. It is even more difficult to directly replace the electronic eye with the same function as the original eyeball without sequelae.

Even if these are done, it stands to reason that the myopia gene should have been identified long ago.

But this is based on normal development, and the world simulated by the life simulator always has Zhou Ming, and the world after Zhou Ming's death will not be displayed.

Zhou Ming will have an influence. Among the futures simulated in the life simulator, the fields of biology and artificial intelligence are almost all developed according to Zhou Ming's development plan. Even other fields are also affected, changing the original development route.

The resources of a society are limited, and a large amount of human and material resources are concentrated in certain fields, so there must be some fields that will not be taken seriously.

Determining the myopia genes has no future research prospects in the era of rapid development of cloning technology and artificial intelligence technology in the future. It is difficult for researchers to apply for funding for research in this area, and the progress will naturally be slow.

Finally, about 100 years later, when people began to conduct a large-scale experiment on human genes, the determination of the myopia gene was picked up again.

And this is why the myopia gene has not been fully determined for a long time in the future.

However, in this era, Zhou Ming's experimental team has just been established for the research on organ cloning technology, and there is still a long way to go before the transplantation of cloned organs, and even cloned eyeballs.

In this age where information technology is developed, but virtual reality technology has not yet entered every household, and people still rely on mobile phones and computers to surf the Internet, entertain, and understand information, who is not facing computers and mobile phones all day long?
Especially those teenagers, they are high-risk groups of myopia. Apart from reading and studying, they also spend their free time either swiping their mobile phones or playing computers.

Whether it is reading a book, playing with a mobile phone or computer, or watching TV, it is easy to cause excessive eye use and excessive eye fatigue.

So many behaviors that induce myopia, how can we not be myopic?
When Zhou Ming was in high school, the time he spent using his eyes meant that he would definitely be short-sighted, but he was not short-sighted.

Therefore, Zhou Ming guessed whether he had the gene to prevent myopia from a very early age.

Later, he found out that Zhou Rui and Song Lina didn't seem to be nearsighted either, so he felt that his lack of myopia was due to his genes.

"Yes, but I heard from your aunt that her nearsightedness is not deep, and she doesn't like to wear glasses, so she doesn't usually wear them. She only wears them when she looks at the blackboard in class.

That's right, I heard that the eyes can't be taken off after being put on. If the degree is not deep, it may recover slowly if you don't wear it often. "

Zhou Ming's mother explained to Zhou Ming that she didn't know where she learned these theories.

However, it can be seen that Song Lina is not what Zhou Ming thought, because of her genes, she cannot be short-sighted.

As for Zhou Ming's cousin Zhou Rui, he didn't study hard in his studies, didn't do much homework, didn't use his eyes too much, and couldn't be short-sighted, so the cause couldn't be determined as genetics.

"Mom, don't listen to those people's nonsense. Those who can return to normal are all pseudo-myopia, which is different from true myopia.

Pseudo-myopia is caused by excessive use of the eyes, which causes the ciliary muscle to continuously contract and spasm, and the thickness of the lens increases, which leads to blurred vision. It can be treated with drugs, acupuncture, ear acupuncture and physical therapy equipment, or through self-strengthening of the eye. Muscle exercise to relax muscles, relieve fatigue, and restore vision to a normal state.

True myopia is due to the elongation of the anterior and posterior diameter of the eyeball, which exceeds the normal average of 24mm, so that after parallel light rays enter the eyeball, the focus falls in front of the retina and cannot be imaged clearly.

More importantly, true myopia will not heal itself, and if the degree is slightly higher, you will involuntarily squint when you are active.

I’ve always told you, don’t read those unauthoritative science popularizations, they are all blind science popularizations. "

After listening to his mother, Zhou Ming said to her helplessly.

There is a professor's son who won many awards in his 20s. She doesn't know how to ask her son if she has any questions. How could Zhou Ming not be speechless.

"I also heard from others that their friends' children are like this. After getting myopia, they will be fine without wearing glasses for a while." Zhou Ming's mother explained.

Although she couldn't understand what Zhou Ming was talking about in terms of ciliary muscle and lens, it was obvious that her and Zhou Ming's explanations were made in a much quieter voice.

"When Lina comes over, don't rush to take her for myopia surgery. I'll find an expert in this field to talk to her about it in detail, and then let her decide whether to have the surgery."

Zhou Ming didn't continue to entangle with his mother about those unreliable science popularization anymore, but brought the topic back to his cousin Song Lina and myopia surgery.

Although the technology of myopia surgery has a history of more than 1983 years since the excimer laser began to appear and develop in 30, its sequelae have not been resolved until now.

Although once myopia surgery is mentioned on the Internet, many people with no sequelae or very slight sequelae will stand up and comment, saying how long it has been since they had the operation and they are living a normal life now, you can go there with confidence. Surgery is such an encouraging word for you.

However, in many comments, a few people with more serious sequelae can always be seen.

The reason for this situation is that with the development of myopia surgery, the probability of serious postoperative sequelae is really not high.

And most of these people have no sequelae, or people with low sequelae, so they will naturally give people the illusion that this kind of surgery is very safe and will never cause problems in the comments.

However, even if the probability of serious sequelae is not high, but with so many people undergoing surgery, there will always be some people who are unlucky to encounter.

And once they meet, it will affect them for the rest of their lives.

Song Lina's relationship with Zhou Ming is pretty good now, so he naturally wants to let her understand the risks involved in this matter, instead of blindly undergoing surgery without knowing anything.

Even if it wasn't Song Lina, but another ordinary relative who came to Zhou Ming, Zhou Ming would clearly explain the risks to them.

"Why, is there any risk in this short-sighted eye surgery? Those people I met in the community, their children who have undergone this surgery have no problems?"

Zhou Ming's mother said to Zhou Ming based on her own experience.

Older people just like this. They always like to judge some things based on their own experience or the experience of those around them.

Most of the time, these experiences are useful for them, and these useful experiences will make them more convinced of their other life experiences, and sometimes use them to educate younger generations.

But there are some things, these experiences don't work so well.

"You have not been here for a long time, the sample size is too small, and the data is not representative at all.

Eyes are the windows to the soul. You really have to rely on other people’s experience to look at this matter. I’m not talking about the whole of Luzhou City. At least you should ask all the children who have undergone myopia surgery in all the communities in this district. just work. "

Zhou Ming said with a smile.

"Then tell me, what's the risk of this thing? Is it too risky?"

Zhou Ming's mother ignored what Zhou Ming said, but asked directly.

"It depends on what kind of surgery she is going to do. There are four types of myopia surgery, namely half femtosecond, full femtosecond, superficial full laser, ICL crystal implantation, half femtosecond, full femtosecond, superficial The three types of all lasers use lasers to subtract the cornea."

When he said this, Zhou Ming noticed that his mother still had a puzzled expression, so he gestured with his hands as eyeballs, and continued, "That's it, isn't myopia just because of protruding eyeballs? Laser surgery subtraction is cutting Drop a little on the front of this part.

The lens implantation is to do addition, to reduce the size of the eye and send it into the eye.

Risks, different surgical risks are not the same, probably vision loss, glare, dry eye syndrome, vision loss, foreign body sensation, pain... and so on.

These sequelae are more or less, there will be some after the operation is over, it depends on whether it is serious or not and how long it lasts.

According to the current survey data, the probability of these sequelae being relatively serious is still quite small, but it must be taken into consideration.

After all, don't be afraid of ten thousand, just in case. "

"So there is such a thing, okay, I will call your aunt in a while and talk to her about it." Zhou Ming's mother also nodded after listening to Zhou Ming's explanation, and said to Zhou Ming .

After learning that Song Lina was going to have myopia surgery, Zhou Ming also became concerned about myopia, and he searched for relevant information afterwards.

After this investigation, Zhou Mingcai discovered that the number of people with myopia in China was almost half of the total.

Although there is no data in recent years like 2017 and 2016, according to the white paper "National Vision Health" released last year, the total number of myopia patients in the total population over the age of 2012 in China in 5 has already Reached 4.5 million.

At this rate of development, by 2020, the myopic population in Huaguo may reach 7 million, accounting for half of the total population.

"Perhaps it's time to develop in this direction?"

After seeing these messages, Zhou Ming thought to himself.
