The PC space lens is made of polycarbonate lenses, and the normal resin (cr-39) lenses are essentially different!PC is commonly known as bullet-proof glass, so the PC lenses adhering to the excellent characteristics of the raw material is super resistance to impact, and because the high refractive index and proportion of light, greatly reduce the weight of the lens, there are more advantages such as: 100% uv protection, 3 to 5 years not yellow.If there is no problem in the process, the weight is 37 percent lighter than regular resin, and the impact force is 12 times as high as ordinary resin.
With the continuous development of science and technology, our company can reach the surface hardening of about 3H.
