Essilor, Zeiss, TAG Heuer, Seiko, Komi and Rothschild all did well. China Gusu (Suzhou) is the birthplace of China glasses. Suzhou's glasses production not only has a long history, but also plays a great role in promoting the development of China's glasses industry. In the early years of Chongzhen in Ming Dynasty (AD 1628), an outstanding technician Sun was born in Wujiang. He has been studious since he was a child. At that time, it was painful for him to see people with poor eyesight, but it was inconvenient to use a "single lens" mirror or the like. So he carefully developed a kind of lens that can often be placed on glasses. After repeated experiments, he invented and created a lens grinder-tractor by using mechanical principle. This tractor, the so-called water orange processed by the classical method, uses the pedal to rotate, and uses mineral sand, white mud and brick ash as abrasives or polishing materials to grind the lenses into convex and concave lenses to meet the needs of eye refraction. Finally, I mastered the polishing technology and polished the lens with natural crystal stone. At the same time, he mastered the "aiming light" (optometry) technology, developed lenses with various luminosity such as presbyopia, myopia and hyperopia according to people's age and vision, and compiled an original "aiming at the mirror with eyes" optometry method to check the environment. In this way, the glasses can fit the eyes, the effect is not bad at all, and it is more convenient and comfortable to wear on the face to meet everyone's vision needs. This is the beginning of independent optometry in China. Later, Sun invented and developed optical lenses with different uses, such as Baihua mirror, Yuan Yang Jing, magnifying glass, polygon mirror and magic mirror. Since then, the glasses made by Sun Qiu Yun have become world-famous. Unfortunately, such an accomplished technical talent died at the age of 33, but he left behind a scientific and technological work called "History of Mirrors", which played an immeasurable role in promoting the glasses manufacturing technology in later generations. After Sun, during the Qianlong and Jiaqing years of the Qing Dynasty, there was another person who made glasses in Suzhou, named Chu Sanshan. He further developed the technology of making glasses, which was quite influential. Suzhou produced two outstanding technical talents who made glasses, Sun and Chu Sanshan, which promoted the formation and development of Suzhou glasses industry at that time. 1735, Suzhou has a manual workshop specializing in the production of glasses. By the Kangxi period of the Qing Dynasty, the production and sales of glasses had flourished in Beijing, Shanghai, Suzhou, Tianjin, Guangzhou and other places. Glasses have become a special commodity.
