Good lens, material is the key. Yue Ming pioneered domestic lenses, broke the situation that materials have been monopolized by foreign countries for a long time, invested in establishing a raw material factory to master the core patented technology, achieved a historic breakthrough, and provided people with bright moon lenses with stable quality for a long time.
Yue Ming gathers global superior resources and cooperates with Mitsui of Japan and KOC of South Korea to establish a global R&D and production center for high-quality lens raw materials. It is one of the few lens enterprises in the world to realize self-sufficiency in raw materials. High-quality raw materials such as 1.7 1, KR resin, KR super-tough, PMC super-bright, etc. independently developed and produced are not only for personal use, but also open for supply to peers, benefiting the whole industry.
A brand integrating R&D, lens manufacturing and sales was established in 2002 and headquartered in Shanghai. Yue Ming takes care of visual health as his own responsibility, and does one thing with his heart, that is, he focuses on providing lenses with good experience and guaranteed quality for 654.38+04 billion people. At present, mainly engaged in optical resin lenses and diamond-encrusted glasses.
Eyeglasses lens
The lens, also called the mirror center, is the center of the picture after installation, which is suitable to be placed in the frame, so it is called the mirror center. Its form can be horizontal or vertical, and the installation is simple and convenient.
Classification, lenses can be divided into the following four types according to different materials. Resin lenses, special lenses, space lenses and glass lenses are mainly classified as glass lenses. Glass lenses are more scratch-resistant than lenses made of other materials, but their weight is relatively heavy and their refractive index is relatively high. Ordinary lenses 1.523, ultra-thin lenses 1.72 or more, and the highest is 2.0. The main raw material of glass lens is optical glass.
