Knowledge about PC lens

Polycarbonate comes from scientists in order to make space exploration equipment to adapt to the special environment of space and research out of the material, it is commonly known as Space lens. Space lenses impact resistant than traditional resin sheet 10 times, 60 times stronger than glass, is the world's most impact resistant lenses, 2.5cm in thickness do bulletproof glass, but also cockpit cover materials, PC is made of viscous material, toughness, not easy to break. Space optics lens become a class lightest lenses, lens space 57% lighter than conventional glass, lighter than traditional resin sheet 37%, due to the high refractive index of the optical PC material is material, so when the lens space at -5.00, thinner than conventional resin sheet 26 percent, with 1.6 high refractive resin sheet as thin.

Excellent impact properties, thin and light, high-definition, high-fidelity, UV, so that such lenses become recognized worldwide movement with glasses.

Consider football, basketball case of physical contact against a strong movement, it is recommended to participate in sports such strong impact users assemble a PC lens, so that you can effectively protect your eyes.
