Rated ANSI Z87.1+ and MIL-PRF-32432 ballistic fragmentation Class 1, it addresses the fogging limitation of the standard LOKI in sealed goggle configuration. Available in five variants — Clear and Smoke lenses in Black and Matte Gray frames, plus Indoor\/Outdoor Black — at comparable pricing.\u003c\/p\u003e\n\n\u003ch2\u003eConstruction and Materials\u003c\/h2\u003e\n\u003cp\u003eThe LOKI-AF shares the same frame and conversion system as the standard LOKI — removable rubber temple arms, included elastic strap, and foam gasket insert — with the addition of an anti-fog lens coating. The anti-fog treatment maintains lens clarity in the sealed goggle configuration, where the foam gasket traps body heat that causes rapid fogging on untreated lenses. Frame options include Black (56003, 56083, 56033) and Matte Gray (56103, 56133), providing tonal variety beyond the standard LOKI's single Black frame. Variants: Clear\/Black (56003), Clear\/Matte Gray (56103), Indoor\/Outdoor\/Black (56083), Smoke\/Black (56033), Smoke\/Matte Gray (56133).\u003c\/p\u003e\n\n\u003ch2\u003eCompliance\u003c\/h2\u003e\n\u003cp\u003eANSI Z87.1+ for high-velocity and high-mass impact.

The sealed foam gasket traps exhaled warm air against the lens surface — without anti-fog treatment, fogging occurs within minutes of beginning physical work in goggle mode. The LOKI-AF's coating extends the usable time in sealed configuration before lens clarity is impacted, particularly relevant for grinding, cutting, and masonry operations where sustained goggle use is required.\u003c\/p\u003e\n\u003cp\u003eThe Matte Gray frame option provides an alternative to Black for facilities with specific frame color preferences or for workers who prefer a different aesthetic. Performance across all variants is otherwise identical — the frame color is the only differentiation between same-lens-tint variants.\u003c\/p\u003e\n\n\u003ch2\u003eStrengths\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAnti-fog coating resolves the primary limitation of the standard LOKI in sealed goggle configuration\u003c\/li\u003e\n\u003cli\u003eConverts between open safety glasses and sealed goggle with elastic strap and foam gasket\u003c\/li\u003e\n\u003cli\u003eMIL-PRF-32432 ballistic fragmentation Class 1 alongside ANSI Z87.1+\u003c\/li\u003e\n\u003cli\u003eTwo frame colors (Black and Matte Gray) provide more variety than the standard LOKI\u003c\/li\u003e\n\u003cli\u003eFive variants covering Clear, Indoor\/Outdoor, and Smoke lens applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eLimitations\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAnti-fog coating provides improved but not indefinite fog resistance in high-exertion goggle use — prolonged sealing in extreme humidity may still cause fogging\u003c\/li\u003e\n\u003cli\u003eFoam seal is a dust barrier only; not rated for chemical splash\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eRecommended Use Cases\u003c\/h2\u003e\n\u003cp\u003eConstruction, manufacturing, utilities, grinding, masonry, cutting, and demolition applications where the worker alternates between open safety glasses and sealed goggle configuration within the same shift, and where anti-fog performance is required in goggle mode.

In sealed goggle configuration, the LOKI-AF maintains lens clarity significantly longer than the untreated LOKI. If you use the goggle mode regularly or during high-exertion work, LOKI-AF is the better choice.\u003c\/dd\u003e\n\n\u003cdt\u003eDoes the anti-fog coating work in glasses mode as well?\u003c\/dt\u003e\n\u003cdd\u003eYes. The anti-fog coating is active in both glasses and goggle configurations. In open temple-arm mode, the coating prevents the fogging that can occur during temperature transitions and high-exertion outdoor work.\u003c\/dd\u003e\n\n\u003cdt\u003eWhat ANSI rating does the LOKI-AF carry?\u003c\/dt\u003e\n\u003cdd\u003eANSI Z87.1+ for high-velocity and high-mass impact. MIL-PRF-32432 ballistic fragmentation Class 1. CSA Z94.3.\u003c\/dd\u003e\n\n\u003cdt\u003eWhat is the difference between Black and Matte Gray frame options?\u003c\/dt\u003e\n\u003cdd\u003eBoth are the same frame in different colors. Protective performance, conversion system, and ANSI\/ballistic certifications are identical. The Matte Gray provides a muted color option for workers or facilities with specific frame appearance preferences.\u003c\/dd\u003e\n\n\u003cdt\u003eCan the LOKI-AF be used for chemical splash protection?\u003c\/dt\u003e\n\u003cdd\u003eNo. The foam gasket provides airborne dust\/debris barrier protection. Chemical splash protection requires dedicated indirect-vent chemical goggles with a liquid-tight seal and appropriate ANSI Z87.1 splash rating.\u003c\/dd\u003e\n\u003c\/dl\u003e","brand":"Ergodyne","offers":[{"title":"Clear \/ Black","offer_id":44106340761688,"sku":"56003","price":29.55,"currency_code":"USD","in_stock":true},{"title":"Clear \/ Matte Gray","offer_id":44106340794456,"sku":"56103","price":29.55,"currency_code":"USD","in_stock":true},{"title":"Indoor\/Outdoor \/ Black","offer_id":44106340827224,"sku":"56083","price":29.55,"currency_code":"USD","in_stock":true},{"title":"Smoke \/ Black","offer_id":44106340859992,"sku":"56033","price":29.55,"currency_code":"USD","in_stock":true},{"title":"Smoke \/ Matte Gray","offer_id":44106340892760,"sku":"56133","price":29.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0594\/1900\/0920\/files\/31nasa9I_jL._SL500.jpg?v=1778908221","url":"https:\/\/wcsafety.com\/products\/ergodyne-skullerz-loki-af-anti-fog-convertible-safety-glasses-goggles-ansi-z87-1","provider":"WC Safety","version":"1.0","type":"link"}
