ESS – CDI – Black – Clear / Smoke Gray – 740-0296

This lightweight high-impact sunglass is the first of its class. 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. Temples now feature slide resistance and holes to accomodate the retention strap
Includes:
– Black frame with Clear and Smoke Gray high-impact lenses,
- an adjustable neck leash,
- micro-fiber cleaning cloth,
- and a protective soft case.
Mil Spec MIL-PRF-31013 and ANSI Z87.1-2015 compliant (when not used in conjunction with Rx Inserts).  All CDI lenses provide 100% UVA/UVB protection.

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.

We invite you to read the ESS lens and glasses sizes chart presenting:

• value of visible light transmission (VLT) for all ESS lenses – it is helpful in choosing the color of the lens in terms of the environment in which it will be used
• information on the impact resistance – why should we choose the ESS glasses
• frames sizes of all ESS glasses models – useful in the optimal adjustment of glasses to the size and shape of the user’s face
• information about the completion of ESS glasses sets – One?, 3LS?, 2X? – these markings will no longer be a secret
