ESS CDI Tactical Sunglasses

The ESS CDI is a medium-fit tactical sunglass built for military and security professionals who need shatter-resistant, high-impact eye protection across changing light conditions. Its 2.2mm lenses meet U.S. MIL SPEC high-impact standards and deliver distortion-free optical clarity across the full field of view. Three variants are available: Black or Terrain Tan frames, each paired with a Clear/Smoke dual-lens kit, and a Black frame with Grey Polarized lenses.

Built for Demanding Environments

The ESS CDI's 2.2mm high-impact lenses are rated to U.S. MIL SPEC standards, meaning they are designed to resist shattering under the kind of ballistic fragmentation and impact forces encountered in hostile environments. For a buyer whose eyes are a mission-critical asset, that baseline matters more than comfort features alone. The lenses also provide 100% UVA/UVB protection, so extended outdoor exposure does not compound the risk.

Optical Precision Without Distortion

ESS's ESSOPTICS system delivers distortion-free optical precision throughout the entire field of view, not just at the center. For tasks that require accurate depth perception and situational awareness at the edges of vision, a lens that distorts at the periphery is a liability. The CDI is designed so that clarity holds from edge to edge.

Fast Lens Changes in the Field

The CDI's Lateral Exchange System allows any available lens color to be swapped quickly without tools. When light conditions shift (moving from bright sun to low-light or indoor environments), a fast lens change means the frame stays on and the transition takes seconds. The Clear/Smoke dual-lens kit included with two of the three variants supports that adaptability directly.

Who This Is For and Isn't

The ESS CDI suits military personnel, law enforcement, and security professionals who need MIL SPEC-rated impact protection and reliable UV blocking across variable light conditions. The Lateral Exchange System and dual-lens Clear/Smoke kit make it a practical choice for buyers who move between bright outdoor and lower-light environments. The medium-fit frame is designed for a mid-range face geometry.

The CDI carries no stated certification to a named ballistic fragmentation standard such as MIL-PRF-31013 or ANSI Z87.1; buyers with a specific duty-rated ballistic eyewear requirement should verify the applicable standard before purchase. The medium fit may not suit buyers who need a small or large frame. The Grey Polarized variant does not include a secondary lens.

Common Questions

What does U.S. MIL SPEC high-impact mean for these lenses?

The ESS CDI's lenses meet U.S. MIL SPEC high-impact standards, meaning they are constructed to resist shattering under significant impact forces. No specific MIL-PRF standard number is stated for this product. Buyers with a duty requirement for a named ballistic standard should confirm the specific applicable specification before purchase.

How does the Lateral Exchange System work?

The ESS CDI's Lateral Exchange System allows the wearer to swap lenses without tools by sliding them out from the side of the frame. This lets the same frame accept any of the available ESS CDI lens colors, so a buyer can adapt to changing light conditions in the field without carrying a second pair of glasses.

Which variants include two lenses, and which include one?

The Black/Clear+Smoke and Terrain Tan/Clear+Smoke variants each include two lenses: a clear lens for low-light use and a smoke lens for bright conditions. The Black/Grey Polarized variant includes a single grey polarized lens. All three variants use the same Lateral Exchange System frame, so additional ESS CDI lenses can be interchanged.

What face size does the CDI fit?

The ESS CDI is designed for a medium fit. No specific measurements such as lens width or temple length are listed for this product. Buyers with a small or large face geometry may find the fit less secure and should consult ESS's fit guidance or try the frame before committing to a duty application.

The Bulletproof Zone Promise

When you buy body armor, you're buying your safety. We don't take that lightly. Here's what every order from Bulletproof Zone includes.

1. Authorized dealer of every brand we carry

Every plate, vest, and carrier we ship comes from the manufacturer directly to our warehouse. We don't sell gray-market product, surplus, or returns. That means factory-fresh stock, the full manufacturer warranty, and real after-sale support — the kind only an authorized dealer can offer.

We maintain authorized-dealer relationships with America's leading body armor brands, including Spartan Armor Systems, AR500 Armor, RMA Defense, Shellback Tactical, Caliber Armor, DFNDR Armor, Protection Group Denmark, BulletSafe, BulletBlocker, and over 40 more.

2. Best price, guaranteed

If you find a lower price at another authorized dealer of the same product within six months of your purchase, we'll refund the difference.

Why the "authorized dealer" requirement? Because gray-market and surplus armor may not be genuine, may have a compromised supply chain, and almost never comes with a manufacturer warranty. We won't price-match against products that may not actually protect you.

3. Free fitment consultation

Body armor only protects you if it fits. Email us a photo and your measurements before you order, and one of our specialists will help you size your carrier and plates correctly — at no charge, no obligation.

4. Trusted by thousands of customers

Bulletproof Zone has been a trusted authorized dealer of America's leading body armor manufacturers for over five years. We have over 4,000 verified Trustpilot reviews from real customers across all 50 states.

Price Match Guarantee — Terms

  • You must have purchased the item from our website before requesting the price match.
  • Discounted items and "free with purchase" items are not eligible.
  • The item must be in stock on the competitor's website at the time of your request.
  • The price match is valid for six months from the date of your purchase.
  • The competitor must be an authorized dealer of the product. Auction sites (eBay, Overstock), discounters, and gray-market resellers do not qualify.
  • The competitor must operate an online store. Brick-and-mortar-only retailers do not qualify.
  • Price match applies to the item price plus shipping. Sales tax is excluded.

To request a price match, email us a link to the product on our site and the same product on the competitor's site within six months of purchase. We'll process the refund.
