The resilient, battle-hardened CDI™ sunglass has a long track record of saving eyes and lives in hostile situations. Now with high-impact, ANSI Z87.1-rated polarized lenses, the CDI™ offers new ways to protect your eyes from hazards and glare.

The ESS CDI Polarized Mirrored Gray high-impact lenses can be easily exchanged 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™ makes interchanging any of the seven available lens colors quick and easy.

Redesigned and Better Than Ever

CDI Polarized Mirrored Gray Kit Includes: A Black CDI frame, one set of 2.2mm high-impact Polarized Mirrored Gray lenses, a micro-fiber pouch/cleaning cloth, and a zippered hard case.

Accessory Lenses are available in: Clear, Smoke Gray, Hi-Def Yellow, Mirrored Copper, Mirrored Silver, Mirrored Gray, and Polarized Mirrored Gray.

All ESS lenses provide 100% UVA/UVB protection.

CDI Rx Inserts are also available.

* The ESS CDI Polarized is compliant with ANSI Z87.1-2010, CE EN 166 and U.S. Federal OSHA (when not used in conjunction with Rx Inserts).

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.
