The PC panel is a lens made of polycarbonate, which is essentially different from ordinary resin (CR-39) lenses. The common name of PC is bulletproof glass. Therefore, PC lenses inherit the excellent characteristics of super impact resistance of raw materials. The high refractive index and light specific gravity greatly reduce the weight of the lens, and have more advantages such as 100% UV protection and no yellowing within 3-5 years. If there is no technical problem, the weight is 37% lighter than ordinary resin board, and the impact resistance is 12 times higher than ordinary resin.
The chemical name of PC is polycarbonate, which is an environmentally friendly engineering plastic. The characteristics of PC lenses: light weight, high impact strength, high hardness, high refractive index, good mechanical properties, good thermoplasticity, good electrical insulation, and no pollution to the environment. PC lenses are widely used in optical discs, VCDs, DVD discs, auto parts, lighting lamps and equipment, glass windows in the transportation industry, electronic appliances, medical care, optical communications, glasses lens manufacturing and many other industries.
The first use of PC materials to make PC lenses was in the United States in the early 1980s, and its characteristics are safe and beautiful. Safety is reflected in the ultra-high crush resistance and 100% UV blocking, the beauty is reflected in the thin and translucent PC lens, and the comfort is reflected in the light weight of the lens. Since the launch of PC lenses on the market, various manufacturers have been very optimistic about the development prospects of PC lenses. They have continuously adopted new processes and new technologies in the design, manufacturing and research of PC lenses to make PC lenses continue to move towards the lightest and thinnest , Development in the hardest and safest direction. With the continuous development of science and technology, high-tech, multi-functional and multi-purpose PC lenses have been continuously introduced to meet the comprehensive needs of consumers in terms of physiology, protection and decoration. The most worth mentioning is the various aspherical PC myopia lens products with polarized light or discoloration. Therefore, we have reason to believe that in the near future, PC lenses will become one of the leading products in the eyewear industry.
