{"product_id":"ess-cdi-tactical-sunglasses","title":"ESS CDI Tactical Sunglasses","description":"\u003cp class=\"product-lead\"\u003eThe 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.\u003c\/p\u003e\n\n\u003ch2\u003eBuilt for Demanding Environments\u003c\/h2\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003ch2\u003eOptical Precision Without Distortion\u003c\/h2\u003e\n\u003cp\u003eESS'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.\u003c\/p\u003e\n\n\u003ch2\u003eFast Lens Changes in the Field\u003c\/h2\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2.2mm High-Impact Lenses:\u003c\/strong\u003e meet U.S. MIL SPEC high-impact standards; shatter-resistant construction\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eESSOPTICS:\u003c\/strong\u003e distortion-free optical precision across the full field of view\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e100% UVA\/UVB Protection:\u003c\/strong\u003e full-spectrum UV blocking on all lens options\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLateral Exchange System:\u003c\/strong\u003e tool-free rapid lens interchange between available colors\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMedium Fit Frame:\u003c\/strong\u003e high-speed, low-drag profile suited to a medium face fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003eBlack \/ Clear+Smoke (740-0296)\u003c\/th\u003e\n      \u003cth\u003eTerrain Tan \/ Clear+Smoke (740-0458)\u003c\/th\u003e\n      \u003cth\u003eBlack \/ Grey Polarized (740-0529)\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFrame Color\u003c\/td\u003e\n      \u003ctd\u003eBlack\u003c\/td\u003e\n      \u003ctd\u003eTerrain Tan\u003c\/td\u003e\n      \u003ctd\u003eBlack\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLens Color\u003c\/td\u003e\n      \u003ctd\u003eClear \/ Smoke\u003c\/td\u003e\n      \u003ctd\u003eClear \/ Smoke\u003c\/td\u003e\n      \u003ctd\u003eGrey Polarized\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLens Thickness\u003c\/td\u003e\n      \u003ctd\u003e2.2mm\u003c\/td\u003e\n      \u003ctd\u003e2.2mm\u003c\/td\u003e\n      \u003ctd\u003e2.2mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWeight\u003c\/td\u003e\n      \u003ctd\u003e0.34 lb\u003c\/td\u003e\n      \u003ctd\u003e0.35 lb\u003c\/td\u003e\n      \u003ctd\u003e0.33 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFit\u003c\/td\u003e\n      \u003ctd\u003eMedium\u003c\/td\u003e\n      \u003ctd\u003eMedium\u003c\/td\u003e\n      \u003ctd\u003eMedium\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eUV Protection\u003c\/td\u003e\n      \u003ctd\u003e100% UVA\/UVB\u003c\/td\u003e\n      \u003ctd\u003e100% UVA\/UVB\u003c\/td\u003e\n      \u003ctd\u003e100% UVA\/UVB\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eImpact Standard\u003c\/td\u003e\n      \u003ctd\u003eU.S. MIL SPEC high-impact\u003c\/td\u003e\n      \u003ctd\u003eU.S. MIL SPEC high-impact\u003c\/td\u003e\n      \u003ctd\u003eU.S. MIL SPEC high-impact\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLens Exchange\u003c\/td\u003e\n      \u003ctd\u003eLateral Exchange System\u003c\/td\u003e\n      \u003ctd\u003eLateral Exchange System\u003c\/td\u003e\n      \u003ctd\u003eLateral Exchange System\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003eKRC-ESS-740-0296\u003c\/td\u003e\n      \u003ctd\u003eKRC-ESS-740-0458\u003c\/td\u003e\n      \u003ctd\u003eKRC-ESS-740-0529\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWho This Is For and Isn't\u003c\/h2\u003e\n\u003cp class=\"product-fit-yes\"\u003eThe 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.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThe 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.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWhat does U.S. MIL SPEC high-impact mean for these lenses?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe 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.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eHow does the Lateral Exchange System work?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe 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.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWhich variants include two lenses, and which include one?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe 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.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWhat face size does the CDI fit?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe 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.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eCan the ESS CDI ship to my state?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe ESS CDI is eyewear, not body armor, and is not subject to the New York or Connecticut body armor shipping restrictions.
