Main Business: PC lens production and sales
Business development process:

In Danyang glasses industry in Jiangsu Province, some people said: "Gao Dongbao is a tempered person who once sharpened." At the age of 16, Mr. Gao entered Danyang Cotton Mill as an apprentice worker. At that time, it was hard to find a steady job. Mr Gao treasured his chances of employment. Although he was a small man, he was ambitious and said to himself: "To eat hard and bring the best Technology learns to be the best skilled worker in the factory. "
To this end, Mr. Gao set himself a study plan, while he studied culture, while learning technology, especially in learning technology, he often "melody, fist", others praised him in learning "art" there is a real one on the path of perseverance the spirit of. Many old workers are often touched by this spirit, so they pass on the technology to him without reservation.
Mr. Gao savvy is very good, with the hands of the old masters who did not have a long time he has become a good mechanic, in a technical contest he also won the award too!
Art Supreme daring! In 1992, Deng Xiaoping's southern tour speech was published, the spring breeze of reform once again blowing all over the motherland. At this time Mr. Gao has been skilled in technology, he not only mastered the lathe technology, but also on machinery, mold, design and other processes are also quite a study.
It is this year, Mr. Gao, with his extraordinary courage and courage, founded a glasses factory screws. However, the screw is small, but the process requirements are high! Therefore, under the conditions to produce high-quality glasses screws is not an easy task. No equipment, Mr. Gao himself; no skilled workers, Mr. Gao hand to teach; no mold, he developed. After untold hardships, high-independent development of stainless steel screws finally popular optical industry, the products are exported to Europe and the United States and Russia and other optical market. Therefore, Mr. Gao also became the first domestic private enterprise to develop stainless steel eyeglasses screws. Today, Mr. Gao's stainless steel screws are still an "evergreen tree" in the industry. The sales are prolonged, but also applied to the aerospace, electronics and other products. Our god Shenliu to God ten use the screws of Mr. Gao product.
Mr. Gao's career development laid a solid foundation for his second pioneering work. In 2001, Mr. Gao is the age of a flower, but he grows strong, the old knife, resolutely to higher and further goals!
After market research, Mr. Gao keenly discovered that PC lenses are the leading products in the future optical market. However, it is difficult to develop and huge investments. For Mr. Gao, lens development is an unfamiliar industry. However, even then, Mr. Gao prefers Tiger Hill, and he solemnly pledged to the industry: "To bring the best PC lenses to the market!"
Mr. Gao said that PC lenses are also called "space films" and "universe films". The chemical name is polycarbonate and is a thermoplastic material. That is, the raw material is in a solid state and is shaped into a lens after being heated. Therefore, the overheated lens of the lens will be distorted after being heated, which is not suitable for hot and humid occasions. PC lenses have a strong toughness, not broken (2cm can be used for bullet-proof glass), it is also known as safety lenses. The proportion of only 2 grams per cubic centimeter, is the lightest material for the lens.
At the same time, Mr. Gao also pointed out that although the PC lens has a broad market prospect, some technical problems have plagued PC chips for better and faster development and popularization. In order to solve technical problems and produce promising PC lenses, Mr. Gao set up his own team of talents on the one hand and long-term cooperation with institutions specializing in the development of PC lenses in foreign countries and Taiwan to make first-class PC lenses by using high-tech means. On the other hand, innovation as its mission, uphold independent research and development, bold innovation, the courage to explore the corporate philosophy, and always take the product development as the core competitiveness of enterprise development; the same time, invest huge sums of money, take the lead in the domestic use of independent intellectual property rights, advanced Production technology, first-class testing equipment, modern management, efforts to enhance Dongbao product quality.
Hard work pays off! After years of hard work, Toho company relies on independent research and development capabilities, and finally successfully overcome the PC lens scratch resistance and internal stress two major technical problems, developed in line with international standards of stress-free PC lenses, while developing a double Strengthen the function. Because of this, Mr. Gao Dongbao has gained a reputation as "the first domestic manufacturer of PC glasses without internal stress".
At present, Dongbao optics set PC lens research and development, production and sales as one, the plant covers an area of 7,000 square meters, the company uses imported PC raw materials, and has a complete set of advanced thermoplastic PC lens dedicated production lines, the production of PC lenses can be achieved More than 6 million.
In addition, the company's products also passed the ISO9001: 2015 quality management system certification, the product fully in line with European Community CE and the United States FDA quality standards, and by the National Eyewear Product Quality Supervision and Testing Center of the test, the product of the technical indicators have reached the standard production .
So far, Dongbao PC lens manufacturing technology has become more mature, and has a vast market space.
As we all know, PC space lenses are made of polycarbonate lenses, and ordinary resin (CR-39) lenses are essentially different! PC is commonly known as bullet-proof glass, so PC lenses adhering to the excellent super-impact resistance of raw materials, and because of high refractive index and light weight, greatly reducing the weight of the lens, there are more advantages such as: 100% UV, 3-5 years will not yellow. Weight 37% lighter than ordinary resin, impact resistance is up to 12 times more than ordinary resin!
Today, Dongbao Optical Co., Ltd. of Jiangsu Province has become a professional manufacturer of polycarbonate (PC) optical glasses. Since its launch, its products have enjoyed huge market competitive advantages with high quality and low price, becoming the leading supplier of PC lens in China "darling". According to market research, Toho PC lenses compared with ordinary PC tablets, its advantage is very prominent.

The wear resistance of more than 1000 grams, the PC lens has a hard and durable anti-flower function, strong anti-attack, can effectively reduce the lens wear probability, long-term to keep the lens clear and natural. At the same time, Dongbao PC lens to improve and improve the PC lens manufacturing process, eliminating internal stress, fundamentally solve the lens rainbow on the visual impact, so that users feel more comfortable visual sense, will not be caused by the distortion of the material Wearers feel dizzy, eye swelling, eye fatigue and other adverse reactions, and the production process does not involve liquid resin raw materials, does not produce any waste, its good thermal stability of the multi-cycle injection molding process possible. After the product life cycle, all kinds of lenses in the only recyclable materials, truly reflects the friendly environment, is an authentic environmentally friendly products. In addition, Dongbao PC lens vacuum plating  have seven inner and outer surface, so that the transmittance of more than 98%, which can effectively eliminate the parties
Reflective, suitable for driving at night, while reducing light dispersion. The Toho PC lenses with lightweight high-quality materials, it is effective in reducing the pressure on the bridge of the nose, so that wearers more comfortable.
