The origin and development of glasses


According to information, the glasses first appeared in 1289 in Florence, Italy, it is said that the world's most important tool is named Al Mato optics and a home to live in the city of Pisa, Italy Spina invention. . American inventor Benjamin Franklin, suffering from myopia and hyperopia, myopia far in 1784 invented the dual-glasses to protect against frequent change of two glasses of torture. In 1825, the British astronomer George Avery invented glasses can correct astigmatism.


     Early images of the glasses and the kind of information few survive in the world. Qianlong, our country has been able to produce glasses, frames of black wooden frame fitted with tying ribbons, crystal grinding the lens to Jiaqing years, the popularity of glasses. Since the 13th century invention of human lens has been polished with crystal glass lens, invented in France in 1937 called acrylic plastic glasses, though not broken, but poor resolution. In 1954 the French company according to the ancestral way by an engineer from the production of materials in the cockpit inspired to the invention of resin lenses, and since then, this lens has become the world's supreme lens Kingdom, is still used today.

The formation and development of China's optical industry can be divided into three historical stages of development

1. The formation of inter-industry Ming and Qing Dynasties gang

     In the history of our country with the development of individual handicraft industry, glasses made from natural materials development spar to the rear glass, the use of glasses began to promote and expand civil, production technology also has a new development.

     China Suzhou (Suzhou) is the birthplace of our glasses, glasses Suzhou production not only historic, but also played an important role in promoting the development of China's optical industry. The early years of the Ming shock frame (AD 1628), Suzhou spectacles in the history of the mountain is now an outstanding technician named Sun Yun ball, Wujiang origin. He grew up studious, when he saw the vision is not healthy, it is very painful, but the "single photo" Mirror of the class and inconvenient to use. So he can devote themselves to develop a regular frame lens on the eye. After repeated trials, he invented the lens grinding machine - led by Tuo car. This led Tuo car, with pedal rotation, using ore sand, lime mud, brick dust and other abrasive or polishing material for, convex and concave lens ground into the lens to accommodate the refractive needs, and finally mastered the "grinding chip "technology. Natural crystal stone with a lens system. He has mastered the "light" now known as refraction) technology, according to the person's age and developed a different vision presbyopia, myopia, hyperopia and other varieties as well as various luminosity of the lens, and the preparation of a set of "Head on over mirror "of the original refraction method. Experience with projects for Habitat. This allows mesh with glasses, the effect is no less, wearing the face is also more comfortable and convenient to fit everyone's needs vision, this is the beginning of optometry territory.

      Following the Sun Yun ball to the Qing Dynasty Emperor Qianlong, Jiaqing, Suzhou and glasses out of a manufacturing talent, named Chu Three Hills. He further developed the technology of manufacturing glasses, influential.

      To the Qing Emperor Kangxi, production and sales of glasses has been booming in Beijing, Shanghai, Suzhou, Tianjin, Guangzhou and other places. Glasses have become a special commodity.

2. Qing Dynasty Shun from the glasses industry

      Since the Opium War in 1840, the successor of the West glasses technology, the rise of the optical industry has opened up a new path. Qing Dynasty, is the first Englishman John • High German (J.hnGoddard), opened in Shanghai in "high German Matheson" franchise machine grinding detection light glasses. After thus connected to other foreigners. Such as child care pole Division (TobiM) opened a "crystal clear Matheson", British Jews, Mao Lei Dayton (Ram5 than n) creation of "Ray Gordon Matheson Mao," and so on. After this point, to 19 years he was in the "high German Matheson" financing for Chinese people set up a "China Lean Optical Company." Since the opening of the company lean glasses, so my glasses industry has a new development. Especially with the great reform in optometry.

     Since the company lean glasses glasses adapted to the needs of our people, but also lower than the price of foreign goods Matheson, soon occupied the market in the country and opened a branch in the country. When the First World War, lean glasses company has opened offices in Beijing, Hong Kong and Chongqing eighteen.

     1935. Shanghai in addition to lean glasses company also opened several large professional eyewear company, including "Maochang, Wu Liang was glasses" and so on. These glasses are equipped with advanced professional optometry and lens processing equipment grinding, cutting edge special machine.

      At the same time, Beijing's glasses industry has been greatly developed. Beijing has opened Sims watches Opticians. Daming eyepiece company (founded in 1937), also have separate offices and posterior eye glasses shop in front of the lens processing workshop. Meanwhile, the original old-fashioned cottage industry production workshop, also will increase the development and innovation of its production techniques, the use of some of the imported materials, so the old glasses in the form sought to update.

3. After the founding of New China's optical industry changes and leap

      Old China, glasses industry, are private shops and family workshops hand in its production and distribution, and its products are mostly for the ruling class of decorations, yield small, expensive, and thus slow the development of invasion. Especially in industrial production. Until the eve of the liberation, the national production of spectacles manufacturers only very few, but very backward production technology, poor product quality, variety monotonous.

      After the founding of new China, under the guidance of the Party's correct line, glasses production began from the small family workshop-style manual production, and gradually to organize co-production of small businesses.

      In addition, a number of defense industry enterprises, instrumentation industry there are some enterprises are turning to optical industry production and processing, business services sector also expanded sales network and to add or increase L optometry equipment, apparatus. Beijing, Shanghai, Guangzhou, Chongqing, also runs short courses DING glasses technology workers and other professional and technical schools as a spectacles sector and train a large number of professional and technical personnel.

      The development of China's optical industry, is the result of thousands of years of development and changes. It has formed a large industry has a certain size and a certain matching production capacity in the whole national economy, which has become an indispensable part of the country and the people and make due contributions.
