During the epidemic, the country has opened the online course model and used electronic devices intensively, and I do not know whether the myopia rate will usher in explosive growth this year.

 

Modern people myopia, need to go to the optician with a pair of myopia cheapest eyeglasses online, that ancient people myopia, should do?

 

Song Dynasty Ye Mengde "Stone forest Yan Yu" volume 10 records:

Ouyang Wenzhong is myopic, often reading is very difficult, but people read and listen to it. During my years in the Government, every time I put in a text, I did not think it was different. A good man has his own looks.

 

Ouyang Xiu has been myopic to reading is very difficult, can only listen to books, which today I am afraid to have 70 or 80 hundred, has greatly affected life.

 

Su Zhe wrote in "Sitting at Night" :

"Young people lose sight in reading, old people often go to bed early because they are afraid of the light."

 

It can be seen that Su Zhe studied too hard when he was young, which caused his eyesight to decline.

 

Du Fu wrote in the Small Cold Food Boat:

"The spring water boat sits like the sky, and the old flower looks like fog."

 

Of course, what Du Zimei said should be "presbyopia", but in that era, we still lack the concept of "myopia", "presbyopia" and "amblyopia".

 

At this stage, there were no glasses in the modern sense, but there were glass lenses that were later used to make glasses.

 

In the Eastern Han Dynasty, Wang Chong mentioned "Yangsui" in "On Heng", and the gold circle with crystal magnifying glass was unearthed from the tomb of Liu Jing, the royal family of the Eastern Han Dynasty. Between 1974 and 1977, the museum of Bo County in Anhui Province unearthed five convex glass lenses in two Eastern Han tombs. The owners of these two tombs were all of Cao Cao's clan. We found all focused fires, and two of them were able to magnify objects.

 

By the Song Dynasty, crystal lenses had often been used in life practice fire, many glass lenses were made very beautiful, widely used as decoration, but its magnification function is often used to read particularly small text, not more fully developed, there is no modern sense of glasses.

 

The earliest eyeglasses invented in the West in the 14th century were actually two foldable lenses joined together, such as those used in a 1380 portrait of St. Paul.

 

In the Ming and Qing dynasties, there were two kinds of names for glasses. One was 叆叇 (aidai), which was the opposite of the Arabic uwainat (glasses).

As early as in the "Ci of Chu" there is a word 叆叇 : "when 叆叇 its 曭t, C, and run belong", here "叆叇" refers to the dim light, this has nothing to do with glasses, but later became a general name for glasses, even Japan's "Japanese Sanai map" also called glasses 叆叇.

 

Written in 1712, it was the first encyclopedic dictionary in Japan, covering astronomy, geography, people, and plants.

 

The second is glasses.

 

Kong Shangren in the "peach blossom fan legend" "Welcome" out, he wrote: "take out the waist glasses to wear." Qianlong fifty-six years (1791), in the Zhengda Hall of light Dakaolin, poetry to glasses proposition.

 

And when it comes to glasses, he has to mention the emperor Yongzheng who said, "Give you two glasses, I don't know if you can look at each other."

 

It is well known that Emperor Yongzheng was very diligent during his reign, sleeping only four hours a day and insisting on personally reading a large number of music records, which also made his eyesight not good, and the Qing Dynasty already had glasses, Yongzheng went on the road of "glasses master", only the first year of Yongzheng to Yongzheng seven years, he had 35 pairs of glasses.

 

According to the archives of the office: "Will be crystal, tea crystal, ink crystal, glass glasses, each more than a few pairs, all to be good." In addition to the use of superior materials, Yongzheng also required to customize glasses according to the twelve hours, if the shooting of a "twelve hours in the Forbidden City", the Yongzheng Emperor each hour of different glasses absolutely become explosive.

 

Glasses went through several stages of development after they were introduced to China.

 

First of all, from the perspective of the frame, it has experienced from no mirror leg to "silk gauze" to metal frame.

Second is the lens. The original glasses are actually reading glasses, the Ming Dynasty Zhang Ning in the "Fangzhou Zayan" said: "The old man faint, do not distinguish fine words, Zhang this thing in the eyes, the word double." Recently, I saw another one at Sun Jingzhang's political participation office and tried again." It can be seen that it is used when the elderly do not distinguish small words.

 

Later, China can self-ashlar lenses, glasses gradually popular, with myopic glasses, the depth is gradually complete. In the Qing Dynasty, Yang Mi people wrote "All men bamboo Ci", he said: "The car from the lively road, sitting diagramming the book without making a sound." Wear glasses to put myopia, learn from his famous old gentleman." It can be seen that myopia glasses were later associated with famous scholars and old men, forming a social atmosphere.

 

Although people often say that people wearing glasses are "cultural people", they still use their eyes scientifically to avoid myopia!
