Since the Opium War in 1840, Western optician technology has been introduced to China, opening up a new path for the rise of the optical industry. At the end of the Qing Dynasty, first of all, the British John G. Goddard (J. hn Goddard) opened a "Gao De Yang Xing" in Shanghai, specializing in machine grinding and inspection glasses. After that, other foreigners will come. For example, TobiM has opened "Ming Jing Yang Xing", the "Lemmon Yang Xing" opened by the British Jewish Remington.
Since then, the Chinese who worked in the "Gao De Yang Xing" in 1911 have raised the "China Lean Eyewear Company". Due to the opening of the Lean Eyewear Company, China's optical industry has made new developments. In particular, there has been a great reform in the field of optometry:
1 began to abolish the long-standing "optical card" optometry glasses used in the old-style shops, using a combination of subject and object optometry.
2 Eliminated the method of making the lens by hand, set up the mechanical grinding equipment, and developed the grinding technology. At this time, not only can the lenses of different natures and specifications be ground, but also the self-made supervised frames. ).
3 In the aspects of inspection, grinding, cutting, loading, correction, and other technologies, due to the adoption of some foreign new technologies and equipment, we have trained a generation of professional talents to make glasses, and soon formed a new one for China's optical industry. The technical team has laid a solid foundation.
