The Rugged Blue SC-260 polycarbonate Diablo safety glasses are protective eyewear with untinted polycarbonate lenses that have anti-scratch coating and UV400 protection. Untinted lenses can be used indoors and outdoors without interfering with color recognition. This protective eyewear"s polycarbonate lenses resist impact and have an anti-scratch coating to prolong lens life. They protect the wearer"s eyes from ultraviolet A (UVA) and ultraviolet B (UVB) light with wavelengths up to 400 nanometers (nm). The polycarbonate wraparound frame provides impact resistance, and built-in nose pads provide comfortable, secure fit. Wide temples increase side protection. This eyewear meets the American National Standards Institute/ International Safety Equipment Association (ANSI/ISEA) Z87.1-2010 and European Standard (EN) 166:2001 personal eye protection standards for quality assurance. Protective eyewear, such as safety glasses or goggles, is worn to shield eyes from hazards, including flying particles, heat, chemicals, and harmful exposure to light. Face shields and helmets may be also be used with protective eyewear, especially when welding or working with molten materials, to provide additional protection. Eyewear is sometimes designed to wrap around the side of the head to extend protection to the periphery; the extent of this protection is measured as "base lens curve." Base lens curve has a typical range of 6 to 12, with a 6 being on the flat end of the scale and a 12 providing the maximum amount of wrap around the head. Protective eyewear is commonly used in the manufacturing and construction industries, among others. Rugged Blue manufactures clothing and safety equipment. The company is headquartered in New Stanton, PA.
