Fake Oakleys Frogskins Sunglasses Cheap for Sale PC resin is an excellent engineering thermoplastics, is only five plastic products with good transparency, but also the fastest growing in recent years, general engineering plastics. Now widely used in the field of optics, automotive, electronics, construction, health care, etc., is particularly suitable for the production of spectacle lenses.
PC lenses Material: POLYCARBONATE derived from space exploration equipment in order to allow scientists to be able to adapt to the special environment of space and come up with the material, so-called lens space.
Features: Thin and light
Space lens optical Cheap Mac Cosmetics Makeup wholesale Outlet lenses become the lightest one class of lenses, lens space 57% lighter than conventional glass, lighter than conventional resin sheet by 37%, due to the high refractive index material is PC material, so when the lens space at -5.00, thinner than conventional resin sheet by 26%, with 1.6 high refractive resin sheet as thin.
Super anti-collision and high toughness
Space than traditional lenses impact resistant resin film 10 times stronger than glass 60 times stronger, is the world's most anti-collision lens, the material commonly known as bullet-proof glass after thickening, PC material is viscous material, toughness, not easy to break.
UV
Both the optical glass or resin sheet material, which in itself is not a function of UV protection, but relies on its coating surface to UV, and PC material itself has anti-ultraviolet function, so the lens either white space or coated tablets s have long-lasting, good isolation UV 290nm-380nm wavelength, but also can prevent cataracts and other eye diseases, such as aging eye lens.
Fully words, Cheap Ray Bans Wayfarer Sunglasses Outlet Sale PC material with ultra-thin, ultra-light, highly crashworthiness, UV light transmittance and good, etc., is the only pan-used transparent plastic material, has good stability and non-conductive characteristics so wide range of applications, while those made of natural material PC lens has the above advantages, especially for a high number, focus on aesthetics, activists, children, older people wear, like the United States with Clause 13 of the children below the age of glasses family PC lenses must be worn.
Before selecting outstanding sunglasses suppliers as partners, provided the lens factory are rigorously tested. Space sheet (polycarbonate) referred to as PC tablets, which first applied to the window on the space shuttle on the sidelines, after the United States after 20 years of Oakley research and development, applied to the field of optical glasses, this material is commonly known as the thick bulletproof glass, PC sheet is also an extremely wear resistant resin lenses, new products are widely used PC ultralight Tiffany and Co Key Necklace Jewelry Outlet lens space, the intensity is 60 times that of glass, lighter weight than glass 7% to UV400 standard, multi-coated filter 100% In addition to UV rays.
