Rated ANSI Z87.1+ and MIL-PRF-32432 ballistic fragmentation Class 1, the LOKI provides versatile protection across general safety glass applications and dust\/debris environments in a single pair. Available in Clear, Indoor\/Outdoor, Blue Mirror, and Smoke lenses with Black frame at $14.99–$27.99.\u003c\/p\u003e\n\n\u003ch2\u003eConstruction and Materials\u003c\/h2\u003e\n\u003cp\u003eThe LOKI features a wraparound polycarbonate lens in a co-polymer frame with removable rubber temple arms. An included foam gasket insert fits around the frame perimeter to form a partial seal against dust and airborne debris when worn in glasses configuration. The included elastic strap replaces the temple arms for goggle configuration, providing head-retention for high-movement applications. The foam insert is flame-resistant and hypoallergenic closed-cell foam. All lens options provide 99.9% UV protection. Variants include Clear (56000), Indoor\/Outdoor (56080), Blue Mirror (56092), and Smoke (56030).\u003c\/p\u003e\n\n\u003ch2\u003eCompliance\u003c\/h2\u003e\n\u003cp\u003eANSI Z87.1+ for high-velocity and high-mass impact. MIL-PRF-32432 ballistic fragmentation Class 1 — this military standard requires the lens to withstand a steel projectile at 660 ft\/s (201 m\/s), approximately 4x the velocity required by ANSI Z87.1+.

Rather than carrying two separate pairs, the LOKI provides both configurations with the same lens and frame. The foam gasket's sealed configuration is effective for airborne dust but is not a certified chemical splash goggle.\u003c\/p\u003e\n\u003cp\u003eThe MIL-PRF-32432 ballistic rating extends the LOKI's applicability to law enforcement, range safety, and security applications alongside standard construction and industrial use. For anti-fog performance in the goggle configuration, the LOKI-AF variant adds anti-fog coating to address the fogging that sealed goggles create by trapping body heat.\u003c\/p\u003e\n\n\u003ch2\u003eStrengths\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eConverts between safety glasses and sealed goggles — one pair serves both dust-protection and open-temple applications\u003c\/li\u003e\n\u003cli\u003eMIL-PRF-32432 ballistic fragmentation Class 1 certification exceeds ANSI Z87.1+ impact standard\u003c\/li\u003e\n\u003cli\u003eFoam gasket reduces airborne dust and debris ingress in glasses configuration\u003c\/li\u003e\n\u003cli\u003eRemovable elastic strap for secure goggle-mode retention during high-movement work\u003c\/li\u003e\n\u003cli\u003eCSA Z94.3 certification for Canadian site compliance\u003c\/li\u003e\n\u003cli\u003eFour lens options cover clear indoor, variable-light, and outdoor bright conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eLimitations\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eNo anti-fog treatment — the sealed goggle configuration can cause significant fogging; consider the \u003ca href=\"\/products\/ergodyne-skullerz-loki-af-anti-fog-convertible-safety-glasses-goggles-ansi-z87-1\"\u003eLOKI-AF\u003c\/a\u003e for anti-fog goggle applications\u003c\/li\u003e\n\u003cli\u003eFoam seal is a dust barrier only — not a certified chemical splash or liquid-tight goggle\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eRecommended Use Cases\u003c\/h2\u003e\n\u003cp\u003eConstruction, manufacturing, utilities, grinding, cutting, masonry, demolition, and law enforcement\/range safety applications requiring ANSI Z87.1+ or ballistic-rated eyewear.

Install the foam gasket insert around the frame perimeter for a sealed dust barrier. The conversion takes approximately 30 seconds and requires no tools.\u003c\/dd\u003e\n\n\u003cdt\u003eWhat is MIL-PRF-32432 ballistic certification?\u003c\/dt\u003e\n\u003cdd\u003eMIL-PRF-32432 is the US military lens ballistic performance standard. It requires the lens to withstand a steel projectile at 660 ft\/s — approximately 4x the velocity of ANSI Z87.1+'s high-velocity impact test. This makes the LOKI suitable for law enforcement, military training, and range safety applications where ballistic fragment protection is required.\u003c\/dd\u003e\n\n\u003cdt\u003eDoes the foam gasket make the LOKI suitable for chemical splash protection?\u003c\/dt\u003e\n\u003cdd\u003eNo. The foam gasket provides airborne dust and debris barrier protection. It is not a certified chemical splash or liquid-tight goggle. Chemical splash applications require dedicated indirect-vent chemical goggles with ANSI Z87.1 splash rating.\u003c\/dd\u003e\n\n\u003cdt\u003eWhy should I choose the LOKI-AF over the standard LOKI?\u003c\/dt\u003e\n\u003cdd\u003eIn sealed goggle configuration, the foam gasket traps body heat and causes significant fogging on standard lenses. The LOKI-AF's anti-fog coating mitigates this, maintaining lens clarity during extended goggle-mode wear. If you plan to use the goggle configuration regularly, the LOKI-AF is the better choice.\u003c\/dd\u003e\n\n\u003cdt\u003eWhat ANSI rating does the LOKI carry?\u003c\/dt\u003e\n\u003cdd\u003eANSI Z87.1+ for high-velocity and high-mass impact. Additionally certified to MIL-PRF-32432 ballistic fragmentation Class 1 and CSA Z94.3.\u003c\/dd\u003e\n\u003c\/dl\u003e","brand":"Ergodyne","offers":[{"title":"Clear \/ Black","offer_id":44106334339160,"sku":"56000","price":26.25,"currency_code":"USD","in_stock":true},{"title":"Indoor\/Outdoor \/ Black","offer_id":44106334371928,"sku":"56080","price":26.25,"currency_code":"USD","in_stock":true},{"title":"Blue Mirror \/ Black","offer_id":44106334404696,"sku":"56092","price":26.25,"currency_code":"USD","in_stock":true},{"title":"Smoke \/ Black","offer_id":44106334437464,"sku":"56030","price":26.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0594\/1900\/0920\/files\/61liVHdMwTL._SX500.jpg?v=1777502191","url":"https:\/\/wcsafety.com\/products\/ergodyne-skullerz-loki-convertible-safety-glasses-goggles","provider":"WC Safety","version":"1.0","type":"link"}
