What did the ancients do if they were short sighted? What if the ancients were short sighted?

Myopia is a type of refractive error. When the eye is in a relaxed state of accommodation, parallel light rays enter the eye and focus in front of the retina, which causes a clear image to not form on the retina, which is called myopia.

Ancient people were very little short-sighted.

The characters are written with a brush.

And it used to be written on bamboo.

The words are very large.

There are not so many modern advanced devices that are harmful to the eyes.

So the chance of myopia is quite small.

What else can I do. I put up with it, and there were no TVs or anything in ancient times, so it was generally not very serious.

It stands to reason that there should be myopia, but in ancient times, myopia could only be like this. Incurable. You can't wear glasses, just like many of us are nearsighted but don't wear glasses.

But the ancient people were very little short-sighted, although the people who read were very eye-catching, but compared with the current time, it was much less, and the ancient people did not read as early as the modern people.

Moreover, the number of people who read books does not account for the majority of the society, and many people do not use their eyes every day, so there are very few myopic people in ancient times.

Around the time of the Qing Dynasty, China began to import glasses from foreign countries.

In ancient times, people mainly used their eyes to read books, and at that time the words on their books were very large, and they were not easy to be short-sighted, unless they had eye diseases, so they had to use a magnifying glass imported from the West, but that thing was only available later.

In ancient times, many people were short-sighted, and many of them also wore glasses.

is like Du Fuzi in the recent hit drama "Menghualu", he has a pair of "Tocharian Qibao Snow Mountain Dragon Tooth Glass Crystal", which makes many netizens curious: "What is this?" ”。

on the Internet, invasion and deletion.

Zhao Xihu of the Southern Song Dynasty recorded in "Dongtian Qinglu": "The old man does not distinguish the detailed book, so as to hide his eyes. ”

Another Song people's notebook, "Diary of Leisure", also provides an example: "Shi Xin broke out of prison and took more than a dozen kinds of water spirits to enter. ”

Water spirits, i.e. crystals. Shi Xin, a fellow villager and friend of Su Xun in the Northern Song Dynasty, may have suffered from presbyopia when he was a law magistrate and used glasses made of crystal to read case files.

Judging from these documents, the people of the Song Dynasty did use glasses, and their names were "叆叇".

So what kind of glasses is Du Fuzi wearing?

Xi Xiaoma consulted our doctor from Huizhou C-MER Ophthalmology Department with questions, and the doctor told Xi Xiaoma: Du Fuzi's crystal slur, according to the effect of enlarging the eyes, should be a pair of farsighted glasses (the myopia lens is a concave lens, which will shrink the eyes from the appearance, rather than magnify, and Du Fuzi's age is unlikely to be presbyopia).

In the state of relaxation of eye accommodation, the external parallel light enters the eye, and its focus falls on the retina, forming a clear image, which is called emmetropia; If the focus does not fall on the retina, it is called nonemmetropia, which is refractive error.

In ancient times, there were copper coins. Copper coins have small seams.

Through small seams. People who are nearsighted will be able to see a clear image.

1. Among the aristocracy, some people use a magnifying glass to alleviate it; Even the nobles had their servants read to them.

2. In the Kangxi period, missionaries brought glasses into China, which is the earliest record of glasses in China.

3. In fact, in ancient times, there was generally no such thing as myopia, because the words of the brush were not only large, but also the posture requirements were particularly strict in ancient times, and no one was generally myopia. If it is congenital, it cannot be ruled out.

First: the earliest record of myopia. Song Dynasty Ye Mengde "Shilin Yan Yu" - Volume 10 recorded:

Ouyang Wenzhong is short-sighted, and it is very difficult to read all the time, but he makes people read and listen to it. In the past few years, every time I enter the text, I am also like ordinary people, and I don't think it's different. Nobles really have their own faces.

The Great Chinese Dictionary takes this as the earliest record of myopia.

Second: myopia also brought a lot of inconvenience to people at that time.

Wen Ying of the Song Dynasty "Jade Pot Qinghua" - Volume 4 records: "Sun Han Gong ......For the right division, to play the Wang, to discuss the rigidity. Knowing the system, in charge of the third class.

Su is short-sighted, and every time he goes to the temple, he recites proficiently and skillfully in order to play in an ensemble. Suddenly, the fluttering ground scattered, scattered and wrong, the ensemble was different, and I was quite surprised. Russia was in a hurry and fell to the ground.

Some people asked for impeachment for dishonorability, and they were released without asking. Because of illness, he was sick and begged to divide his affairs. If it is not allowed, the doctor will be sent to see him and order acupuncture.

The public nature is rigid, and he said to the doctor: The parents are complete, and they lose their care, causing rashes, but they have a number of life and death in the case of broken needles, and they are not healed. I can't afford it.

Because of myopia, he was so frightened that he was sick and died in a hurry.

During the Ming and Qing dynasties, myopia glasses were introduced to China, providing some help to people with poor eyesight, but they could not wear glasses when meeting their bosses in the Ming and Qing dynasties.

Thirdly, people who are short-sighted were also often ridiculed in ancient times. The Qing Dynasty game owner's "Xiaolin Guangji" recorded many such jokes that mocked myopia.

In ancient times, because television, computers, and mobile phones were not available, there were relatively few people with myopia. However, the popularity of modern television, computers, mobile phones, etc., has led to more and more people with myopia, and myopia has shown a trend of younger age, which has a deep impact on people's work, life and study. Children under the age of 18 are nearsighted, because they are still in the stage of vision development, and taking medication in time can improve myopia.

It is recommended to take Joyeye Vision Nutrients, twice a day, one sachet each time, take it with warm water, insist on taking it for a period of time, the degree of myopia will be reduced, and the younger the age, the easier it is to recover.

The probability of the ancients suffering from myopia was not much.

1. Most people don't know how to read, and not many people can afford to read at that time, after all, there are few scholars, and only people with good family conditions or status can afford to read, such as before liberation, they can be a gentleman after finishing primary school.

2. They have very little nearsightedness, and there is no general environment for the formation of myopia.

1) No computer, TV, no need to stare at the screen all day long; They don't have game consoles, so they don't have to worry about their kids not coming out for hours or even days in an internet café.

2) In ancient times, natural science was not developed, and students at that time read very few books, such as no foreign languages, physics, chemistry, etc., and mathematics was only simple operations such as addition, subtraction, multiplication and division, mainly the Four Books and Five Classics, and a "Analects" to read for several years.

3) Ancient students did not read much, and the scientific examination was mainly to write articles, which did not require a lot of reading (there were few books to read), and reading under a kerosene lamp had a weak effect on the aggravation of myopia (I have verified this view).

4) In order to make the best use of natural light, go to bed early and get up early, outdoor reading or writing is conducive to preventing myopia.

Second, the harm of myopia in ancient times was very small.

1. The ancients read private schools, and there is no current blackboard, so it will not be difficult to see the blackboard, and there is no need to think of any way to get close;

2. The life of the ancients was slow, and the traffic was mainly horseback riding and walking, so there was no need to worry about traffic safety, so the harm of suffering from proximity was small.

3. If you are short-sighted, you can move the book and your eyes a little closer, and the words are much larger than the ones printed now.

4. The ancients did not have glasses, so they did not develop to height, and they rarely suffered from complications.

3. The ancients had the nature to prevent myopia**.

1. The previous books are all large characters, although there is no punctuation, but the font size is large, so you don't need to stick it very close.

2. The ancients used a brush to write, which was relatively long, and the eyes could not stick to the paper, and the distance from the word was farther, and the words written were relatively larger, which objectively played a certain preventive role.

3. The ancients did not have glasses, which seems to be unfavorable, but objectively it can prevent the deepening of myopia, so the harm of myopia is very small, and there are basically no myopic complications such as vitreous opacity (see my glasses topic for the theoretical basis).

5. In ancient times, there were many high-rise buildings blocking the line of sight, and there was a wide field of vision around the outing, and there were many outdoor activities, which was conducive to the prevention of myopia.

6. In addition, the ancients had the effect of preventing myopia by walking, riding horses, and living in the wild, so the myopia of the ancients was very small, and the harm was very small, which was nothing compared with other diseases.

Myopia is also a very inconvenient thing for modern people, but we still have glasses and myopia surgery, so many people are curious, if there were no glasses in ancient times, what should people do with myopia? After all, there was no electricity in ancient times, and many scholars were poor and reluctant to use candles, and they had to study hard, so the problem of myopia must be indispensable.

Personally, I feel that the ancient people did not have myopia, and even if they did, they didn't know that it was myopia, because the ancient people did not have so many high-tech products, such as mobile phones, ipads, TVs, computers, so many electronic products, and the ancient people paid great attention to health preservation, and the things they ate were very healthy. Therefore, we must pay attention to the rational and scientific use of eyes, proper nutrition of diet, and the help of Jiajiamin.

In ancient times, there were very few people who had myopia, and even if they had myopia, they used traditional Chinese medicine and acupuncture to ** myopia, which was much more useful than laser surgery, and there would be no sequelae.

Most of the literati in ancient times were short-sighted, especially those who were poor and hardworking, and most of them were severely myopia. Usually they are nearsighted, and they --- see things closer as if we didn't wear glasses.

Ancient people were also short-sighted, and not only modern people. It's just that there were few people who were short-sighted in ancient times, and at that time they were not as advanced as in modern times, and people at that time didn't know that it was myopia, and there was no good way. In the late Qing Dynasty, under the influence of Western countries, there were glasses.

Yes! There must be, some are congenital deficiencies that lead to myopia, and some are acquired! However, there is no way to cure it, but after the Tang Dynasty, it is common to wear the kind of concave lens that is similar to a magnifying glass.

Regarding the problem of acquired eyes, there were not many social media in ancient times, just reading and writing, and reading books at night. Repost a post, it's quite interesting: what if the ancients had myopia? First, the ancients suffered from myopia.

Yes, but there are very few people who are nearsighted, and there is basically nothing that can be done. At that time, myopia was not a big harm, and it was much smaller than now.

Very rarely, because there were no computers and televisions at that time, so it was unlikely, but there were still, but they were all after getting older.

Huiah, there are lenses, (Qing Dynasty).

The ancients were also short-sighted. However, compared with modern people, people in ancient times did not suffer from myopia, and it was usually literati who suffered from myopia. Sima Guang, Bai Juyi, and Ouyang Xiu all suffer from myopia.

In ancient times, Chinese medicine was developed, and acupuncture and medicine were often used to restore vision. Sun Simiao, a famous medical scientist in the Tang Dynasty, listed as many as 71 prescriptions for medical eyes, eye protection, and eye clarity in the sixth volume of "Preparing for Emergencies", many of which are good vision health products.

The modern popular method of correcting and restoring vision through physical means - wearing glasses has long been thought of by the ancients. In the pre-Qin period, people had already used a magnifying glass. In 1980, archaeological excavations unearthed a magnifying glass in the early years of the Eastern Han Dynasty, which is a gold circle inlaid crystal piece, with a diameter of centimeters, which can be magnified 5 times.

By the end of the Ming Dynasty, wearing glasses was not uncommon, and making glasses became a new skill, and China's first monograph on glasses, "The History of Mirrors", also appeared at this time. At the end of the Ming Dynasty and the beginning of the Qing Dynasty, Sun Yunqiu, an optical instrument manufacturer, took the lead in using the grinding disc to light technology, and used crystal grinding to make lenses, with 72 kinds of mirror methods such as presbyopia, myopia, and telescopes.

You have to ask the ancients about this, and there were no glasses at that time!
