ESS CDI Sunglasses, Black & Terrain Tan, Clear & Smoke Grey Lens Set

(description copied from archived official webstore, 2008 ver.) This lightweight high-impact sunglass is the first of its class. Available in five colors, the CDI’s™ extra-thick polycarbonate lenses can be easily interchanged for quick adaptation to your environment. Its high-speed low-drag frame and shatter-resistant lenses make the CDI™ comfortable and cool enough for downtime yet functional and rugged enough for the battlefield. Medium Fit. The CDI’s Lateral Exchange System™ allows quick lens interchange. Includes: Black frame with Clear and Smoke Gray high-impact lenses, an adjustable neck leash, micro-fiber cleaning cloth, and a protective soft case. Other lens colors are available in Hi-Def Copper, Hi-Def Yellow, and Mirrored Silver. * Mil Spec MIL-PRF-31013 and ANSI Z87.1-2003+ compliant (when not used in conjunction with Rx Inserts). All CDI™ lenses provide 100% UVA/UVB protection. Important safety note for CDI™ Rx Insert users operating in proximity to fragmentation hazards: ESS strongly recommends the use of high-impact polycarbonate prescription lenses to optimize impact resistance in the CDI™ sunglass. High-impact polycarbonate prescription lens material will maximize the impact resistance of the system well beyond that offered by CR-39 resin or other common materials used in prescription lens manufacturing.
