Who wears glasses in history books is?
Humans may have discovered as early as 1000 years ago that "lenses" made of transparent crystals or gems have the function of magnifying images; However, it is said that it was only at the end of 13 that the lens was really embedded into the frame and made into "glasses", which appeared in China and Europe at the same time. Some people say that it was invented by an unknown craftsman in China; Some people say it's Alessandro Dispina, a post in Dogar, Italy in the middle ages. Others say it was invented by roger bacon, a British scholar in the 3rd century.
In 1260, Kyle Poirot once described an old man in China reading fine print with glasses. It is said that the glasses in ancient China were oval, and the lenses were made of crystal stone, seasonal, topaz or amethyst, which were set in a tortoise-shell frame, glued to the temples with bronze mirror feet, tied to the ears with strings, or directly fixed on the hats. Moreover, glasses were expensive at that time, so they were regarded as a symbol of status. It is said that there is a record that a squire traded a horse for a pair of glasses.
In Europe, glasses were invented in Italy at the end of 13 century. Venice and Nuremberg at that time were famous in Europe for making highly transparent lenses. However, at that time, glasses can only be said to be magnifying glasses, and they were held in their hands when reading.
2. Who are the sunglasses? Glasses were invented by China. There are seven origins. Xinhuanet Lanzhou May 6 (Reporter Sun Yong) Words such as "stealing the light from the wall" and "ten years of cold window" spread in Chinese, which reflected the hard work of ancient scholars in China.
However, I believe many modern people will have such confusion. They use too many eyes to read books. What should they do if they have vision problems? Zhao Mengjiang, director of Gansu Collection Association, found that in order to solve this problem, ancient people in China invented rock crystal glasses long ago. After studying China ancient documents, unearthed cultural relics and nearly 1,000 pieces of his own collection, Zhao Mengjiang thinks that there are at least seven origins for the invention of crystal glass in ancient China: First, China has a long history of developing and utilizing crystal glass in ancient times.
Zhao Mengjiang's research found that in the Neolithic Age five or six thousand years ago, China people had been able to process exquisite natural crystal stones such as beads, pendants, pendants and rings. By the Xia, Shang and Zhou Dynasties, he had accumulated rich experience in processing and polishing crystal objects.
Second, the ancients discovered and applied the principle of crystal optics. Zhao Mengjiang believes that when the ancients cut the crystal into pieces and polished it, they naturally found that the flat crystal pieces (rings and secondary mirrors) had magnifying effect, so they made convex lenses in labor practice.
Third, the need for sun protection when observing solar eclipses and astronomical phenomena in ancient times. According to Shangshu Shundian, when Shun Di was in China, people used Xuan Ji Yuheng to observe various celestial bodies and their evolution.
Xuan Ji is a kind of color lens, which is installed on the long tube of Yuheng. In the morning, use colored lenses to block dazzling sunlight or bright moonlight, which hinders observation. Fourth, the emergence and development of ophthalmology.
In Oracle Bone Inscriptions of Shang Dynasty, there were records about eye diseases. Chao, a physician in Sui Dynasty, presided over the compilation of Etiology in the first year of Sui Daye, in which refractive diseases such as myopia (eyes can't be farsighted), astigmatism (eyes are boundless), diplopia (one thing can see two things), strabismus (eyes are biased) and amblyopia (eyes are unclear) have been discussed.
Verb (abbreviation of verb) The development of metallurgical technology and handicraft industry. Archaeological excavations prove that China entered the Bronze Age about 4,000 years ago. Gold can be made more than 3000 years ago; Steel can be smelted 2500 years ago, which can provide more and more advanced tools for grinding glass.
At the same time, China's developed handicraft industry and silk weaving industry provide favorable conditions for glasses frame technology and packaging materials. Six, the emergence of writing, the invention of papermaking and printing.
Corrective refractive glasses are mainly used to watch small objects and words. The earliest mature characters in China were produced in Shang Dynasty. At that time, Oracle Bone Inscriptions's sculpture was quite small and looked laborious, so a magnifying glass was needed.
With the invention of papermaking in ancient China, the appearance of movable type printing and the introduction of Buddhist culture, scholars recorded and wrote a large number of classics, saying that the fine print of flies is difficult to identify, so it is natural to need an eye aid. Seven, the emergence and development of optics.
In the 5th century BC, Mozi put forward the theory that light shines in a straight line and has reflective characteristics. Shen Kuo in the Northern Song Dynasty discussed the imaging theory of geometric optics, concave mirror and convex mirror in Meng Qian Bi Tan, which further laid the foundation of China's optical theory.
According to Zhao Mengjiang's research, the earliest glasses in China are actually just a simple crystal lens, which has been matured and perfected in the long historical evolution since then. However, natural crystal stone itself is expensive, so China's ancient glasses can only be a luxury for the rich. It was not until the late Qing Dynasty that China began to produce optical glass that glasses gradually became popular and developed in China.
(End) (Source: Xinhuanet)-. There are many theories about the invention of glasses.

3. Why didn't anyone wear glasses in ancient times? There was myopia in ancient times, but not much.
Because there were no computers and televisions in ancient times, there were not many scholars in ancient times, and the font size of books was printed by block printing, so the font size was relatively large and it didn't look very hard. So there is not much myopia. Most people who are nearsighted are scholars, and the reason for myopia is that kerosene lamps are dim.
Ancient methods to deal with myopia
The ancients suffered from myopia and could do nothing. This can also be seen from some historical materials and jokes. In the Ming Dynasty, someone wrote a poem mocking myopia: "Laughing at your eyes is strange, so Gigi Lai asked who it was?" The sun shone marbles through the window lattice, and the moon moved to pick up sticks. I looked at the painted wall, black and blue, locked the book box and twisted my eyebrows. More funny, blowing lights burns lips and skin. "The image of myopia, which can only be lived in the fog of Yunshan for a lifetime, came alive in this limerick.
Li Bai, Lu You and many other poets were nearsighted, but there was nothing they could do at that time.
In the middle of15th century, western eyes were introduced to China.
4. Who are the players with glasses in 4.NBA history? There are many players who wear glasses in NBA history, such as Kareem Abdul Jabbar and Horace Grant.
Karim Abdel-Gabbar:1Born on April 6th, 947 in new york, USA, he is a former American professional basketball player and center, nicknamed "Tiangou". In 1980s, he invented a pair of glasses that can correct myopia and protect eyes during sports, which was loved by many athletes at that time, and Jabbar was one of the iconic figures.
From 1970, he joined the Bucks as the No.1 scholar, including NBA championship, regular season MVP, finals MVP, scoring champion, all-star, best rookie, first defensive lineup, best athlete and other honors for 20 seasons, which left the younger generation behind. Now many fans don't know much about Jabbar, but when you think about hook scoring and sports glasses, Jabbar will definitely appear in your mind.
Horace grant:1965 was born in Augusta, Georgia, USA. He is a former American professional basketball player, nicknamed "Cobra" and a power forward/center. Horace Grant is not only the main force of Chicago Bulls' first three consecutive championships, but also the third scorer in the team, and together with Michael Jordan and Scott Pippen, he forms the Jackson-Phil-Jackson triangle attack system.
He won the NBA championship four times, was selected into the NBA All-Star Team from 65438 to 0994, and was selected into the NBA Best Defensive Team four times. In 2004, Horace Grant announced his retirement.
5. What should the ancients do if they were nearsighted? Matteo Ricci, an Italian missionary, was introduced to China in the middle and late Ming Dynasty. At that time, only the nobles in the palace could enjoy it. China people began to make their own glasses in the early Qing Dynasty. Sun was a native of Wujiang County in the late Ming Dynasty. Born in Chongzhen for three years (1630). When he was young, he didn't like the imperial examination, but he was keen on scientific research. He especially likes to delve into mechanical manufacturing and measurement mathematics. Later, Sun specialized in the development of optical instruments.
At that time, there were no glasses on the bridge of the nose, but only one "mirror" in hand, commonly known as "single mirror". In the late Ming Dynasty, Zhu Yunming (Zhu Zhishan), one of the four gifted scholars in Gusu, often used a single mirror to "borrow light" because of his high myopia. Seeing that many people are inconvenient to do things because of poor eyesight, Sun made up his mind to develop a kind of glasses that can be placed on the bridge of the nose.
At that time, glasses imported from abroad were all made of glass. Inspired by the study of "glasses" by Song people in the past, Sun decided to use crystal as the raw material of lenses and polish them by hand. After many experiments, Sun finally mastered the technology of grinding glasses to get light. He grinds out reading glasses suitable for people over 60 years old, glasses with few glasses suitable for people over 40 years old, binoculars, low-beam glasses and other glasses, so that people in need can wear glasses according to their different eyesight to achieve the effect of seeing things clearly.
Sun Qiu Yun not only polished lenses of various degrees according to different vision defects, but also greatly improved the appearance and shape of glasses, so that the single-lens glasses that could only be held by hand developed into double-lens glasses with temples placed on the bridge of the nose.
Sun glasses made a sensation in the whole country at that time and were widely welcomed and used.
Besides making glasses, Sun also combined convex lens and concave lens to make the first telescope in China. At that time, the telescope was called a "thousand-mile mirror".
Sun also created the "storage eyepiece (magnifying glass)", which can be held in your hand to see tiny things, and the "inspection micromirror" (microscope), which is composed of magnifying glasses and other mirrors, and can be changed from small to large to see through autumn. He developed a "kaleidoscope" (also known as a "hundred flowers mirror"), which can melt dozens or hundreds of things; The "magic mirror" (similar to the current "ha ha mirror") can produce images that make people look great and ironic.
In addition, Sun also developed a "reflector", which is a searchlight device. Concave mirror magnified the light source and used it as a reflector to reflect the light in one direction, which was earlier than the "searchlight" made by Russian Kubin who put the reflector behind the light source 1779 years ago. Sun also made a natural clock (an ancient clock) to judge the time accurately, and created a night mirror, a sunset mirror, a demon mirror, a polygon mirror, a Yuan Yang Jing, a half mirror and a fire mirror.
Later, Sun wrote a book about his experience in making mirrors, called History of Mirrors. When the book was published, he asked his mother for a preface and thanked her for cultivating his kindness. The History of Mirrors systematically expounds the history, principle and making method of mirrors.
Joseph Needham, a famous scientist and professor at Cambridge University in England, wrote Sun's inventions and achievements into his monograph.
Sun died in the first year of Kangxi in Qing Dynasty (1662). However, his great invention and his book A History of Mirrors have become indelible memories in human history, handed down from generation to generation.
