Combined with Uvextra anti-fog coating on both lens surfaces, the Tirade addresses the two primary failure modes of budget eye protection: fogging and particle ingress from the frame perimeter.\u003c\/p\u003e\n  \u003cp\u003eBoth lens options — clear for general indoor\/outdoor use and gray for bright-light outdoor environments — carry the ANSI Z87.1+ high-impact rating. The polycarbonate construction keeps total weight under one ounce, reducing fatigue in full-shift wear.\u003c\/p\u003e\n\n  \u003ch2 style=\"color:#c8a84b\"\u003eLens Options Comparison\u003c\/h2\u003e\n  \u003ctable style=\"width:100%;border-collapse:collapse;margin-bottom:24px\"\u003e\n    \u003cthead\u003e\n      \u003ctr style=\"background:#1a2433\"\u003e\n        \u003cth style=\"padding:8px 12px;text-align:left;border:1px solid #333;color:#c8a84b\"\u003eModel\u003c\/th\u003e\n        \u003cth style=\"padding:8px 12px;text-align:left;border:1px solid #333;color:#c8a84b\"\u003eLens\u003c\/th\u003e\n        \u003cth style=\"padding:8px 12px;text-align:left;border:1px solid #333;color:#c8a84b\"\u003eCoating\u003c\/th\u003e\n        \u003cth style=\"padding:8px 12px;text-align:left;border:1px solid #333;color:#c8a84b\"\u003eBest For\u003c\/th\u003e\n      \u003c\/tr\u003e\n    \u003c\/thead\u003e\n    \u003ctbody\u003e\n      \u003ctr style=\"background:#111\"\u003e\n        \u003ctd style=\"padding:8px 12px;border:1px solid #333\"\u003eS4040\u003c\/td\u003e\n        \u003ctd style=\"padding:8px 12px;border:1px solid #333\"\u003eClear\u003c\/td\u003e\n        \u003ctd style=\"padding:8px 12px;border:1px solid #333\"\u003eUvextra Anti-Fog\u003c\/td\u003e\n        \u003ctd style=\"padding:8px 12px;border:1px solid #333\"\u003eIndoor, manufacturing, temperature transitions\u003c\/td\u003e\n      \u003c\/tr\u003e\n      \u003ctr style=\"background:#1a2433\"\u003e\n        \u003ctd style=\"padding:8px 12px;border:1px solid #333\"\u003eS4041\u003c\/td\u003e\n        \u003ctd style=\"padding:8px 12px;border:1px solid #333\"\u003eGray\u003c\/td\u003e\n        \u003ctd style=\"padding:8px 12px;border:1px solid #333\"\u003eUvextra Anti-Fog\u003c\/td\u003e\n        \u003ctd style=\"padding:8px 12px;border:1px solid #333\"\u003eOutdoor, construction, bright sunlight\u003c\/td\u003e\n      \u003c\/tr\u003e\n    \u003c\/tbody\u003e\n  \u003c\/table\u003e\n\n  \u003ch2 style=\"color:#c8a84b\"\u003eSealed Frame Design and Foam Gasket\u003c\/h2\u003e\n  \u003cp\u003eThe defining feature of the Tirade over standard safety glasses is the continuous foam gasket bonded to the inner lens perimeter. This seal prevents fine particles — metal filings, wood dust, concrete dust, and fine chemical powder — from entering around the frame edges. The seal does not make the Tirade equivalent to a sealed indirect-vent goggle: it is not rated for liquid splash and does not replace goggle-class protection for chemical exposure. For particle and dust environments at or below the safety-glass hazard threshold, however, the gasket provides meaningful additional protection over open-frame alternatives.\u003c\/p\u003e\n\n  \u003ch2 style=\"color:#c8a84b\"\u003eANSI Z87.1+ and Uvextra Anti-Fog\u003c\/h2\u003e\n  \u003cp\u003eBoth models carry the Z87+ marking, confirming high-velocity impact certification at 150 fps — not just the basic drop-ball test required for standard Z87 glasses. This satisfies OSHA 1910.133 and 1926.102 requirements for eye protection in grinding, machining, and high-particle environments. The polycarbonate lens absorbs 99.9% of UV-A and UV-B radiation.\u003c\/p\u003e\n  \u003cp\u003eUvextra is a permanent anti-fog chemistry bonded to both inner and outer lens surfaces. Unlike wipe-on treatments that degrade quickly, the bonded coating maintains fog resistance through repeated cleaning with lens cloths and mild cleaning solutions. This matters in cold-storage and food-processing environments where glasses fog immediately when workers move between climate zones.\u003c\/p\u003e\n\n  \u003ch2 style=\"color:#c8a84b\"\u003eStrengths and Limitations\u003c\/h2\u003e\n  \u003cp\u003e\u003cstrong\u003eStrengths:\u003c\/strong\u003e ANSI Z87.1+ high-impact certified; peripheral foam gasket blocks particle ingress at frame edges; permanent Uvextra anti-fog on both lens surfaces; lightweight polycarbonate construction; adjustable temples for varied head sizes; UV 400 protection standard.\u003c\/p\u003e\n  \u003cp\u003e\u003cstrong\u003eLimitations:\u003c\/strong\u003e foam gasket seal does not qualify the Tirade for liquid splash or chemical splash environments — a sealed indirect-vent goggle is required for those hazards; gray lens is not polarized, providing brightness reduction without polarized glare elimination; no rubberized nose pads, which reduces grip during high-perspiration conditions; not suitable for over-glasses use on prescription wearers.\u003c\/p\u003e\n\n  \u003ch2 style=\"color:#c8a84b\"\u003eRecommended Use Cases\u003c\/h2\u003e\n  \u003cp\u003eThe Tirade is well suited for grinding, cutting, sanding, concrete work, and dusty manufacturing environments where standard open-frame glasses leave gaps at the lens perimeter. The sealed design and anti-fog coating also make it a strong choice for food processing and cold-storage operations. For prescription eyeglass wearers, the \u003ca href=\"\/products\/uvex-astro-otg-3001-safety-glasses\" style=\"color:#c8a84b\"\u003eUvex Astro OTG 3001\u003c\/a\u003e remains the correct format. For liquid-splash environments, a goggle-class protector is required regardless of frame seal rating.\u003c\/p\u003e\n\n  \u003ch2 style=\"color:#c8a84b\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n  \u003ch3 style=\"color:#e0e0e0\"\u003eWhat is the difference between the S4040 and S4041?\u003c\/h3\u003e\n  \u003cp\u003eThe S4040 has a clear lens and the S4041 has a gray tinted lens. Both use the same sealed Tirade frame with Uvextra anti-fog on both lens surfaces. The clear lens is suited for indoor and low-light environments; the gray lens reduces glare for outdoor work under direct sunlight. Protection level and coating are identical between models.\u003c\/p\u003e\n\n  \u003ch3 style=\"color:#e0e0e0\"\u003eDoes the foam gasket make the Tirade rated for chemical splash?\u003c\/h3\u003e\n  \u003cp\u003eNo. The foam gasket is a dust and particle seal, not a liquid seal. The Tirade does not carry a splash-proof or goggle-class rating. For liquid or chemical splash hazards, a sealed indirect-vent goggle rated to ANSI Z87.1 D3 (splash) or D4 (dust and splash) is required. The Tirade addresses particle ingress at the frame perimeter — it is not a goggle substitute.\u003c\/p\u003e\n\n  \u003ch3 style=\"color:#e0e0e0\"\u003eIs the Uvextra anti-fog coating permanent?\u003c\/h3\u003e\n  \u003cp\u003eYes. Uvextra is a bonded chemistry applied during manufacturing, not a surface wipe-on treatment. It withstands repeated cleaning with lens cloths and mild solutions under normal conditions. Harsh chemicals, abrasive wiping, or undiluted alcohol will degrade any lens coating over time — standard lens care practices apply. The coating does not wear off through normal daily cleaning.\u003c\/p\u003e\n\n  \u003ch3 style=\"color:#e0e0e0\"\u003eIs the Uvex Tirade ANSI Z87.1+ rated?\u003c\/h3\u003e\n  \u003cp\u003eYes. The Tirade carries the Z87+ marking on the lens, indicating it passed the high-velocity steel ball test at 150 fps required for the + designation. This satisfies OSHA 29 CFR 1910.133 requirements for eye protection in environments with flying particle hazards. The + suffix distinguishes it from basic Z87 (drop-ball only) certification.\u003c\/p\u003e\n\n  \u003ch3 style=\"color:#e0e0e0\"\u003eCan the Tirade be worn over prescription glasses?\u003c\/h3\u003e\n  \u003cp\u003eNo. The foam gasket and close-fitting frame design are incompatible with prescription frames underneath. Prescription eyeglass wearers require an over-the-glasses (OTG) model. The \u003ca href=\"\/products\/uvex-astro-otg-3001-safety-glasses\" style=\"color:#c8a84b\"\u003eUvex Astro OTG 3001\u003c\/a\u003e is designed to bridge over Rx frames while meeting Z87+ requirements.\u003c\/p\u003e\n\n  \u003ch3 style=\"color:#e0e0e0\"\u003eHow does the Uvex Tirade compare to the Uvex Hypershock?\u003c\/h3\u003e\n  \u003cp\u003eBoth are ANSI Z87.1+ rated Uvex safety glasses, but they serve different use cases. The Tirade adds a foam gasket for particle sealing, making it better for dusty environments. The Hypershock offers more lens coating options (HydroShield, polarized, photochromic) and has rubberized grip elements for active wear. For grinding and dusty work, the Tirade's sealed frame is an advantage. For comfort and coating variety in cleaner environments, the Hypershock has a broader selection.\u003c\/p\u003e\n\n  \u003cp style=\"margin-top:32px;padding-top:16px;border-top:1px solid #333;font-size:0.9em\"\u003e\n    \u003cstrong\u003eRelated from WC Safety:\u003c\/strong\u003e\u003cbr\u003e\n    \u003ca href=\"\/collections\/safety-glasses\" style=\"color:#c8a84b\"\u003eAll Safety Glasses\u003c\/a\u003e  | \n    \u003ca href=\"\/products\/uvex-hypershock-safety-glasses\" style=\"color:#c8a84b\"\u003eUvex Hypershock Safety Glasses\u003c\/a\u003e  | \n    \u003ca href=\"\/products\/uvex-astro-otg-3001-safety-glasses\" style=\"color:#c8a84b\"\u003eUvex Astro OTG 3001 (OTG)\u003c\/a\u003e  | \n    \u003ca href=\"\/collections\/safety-glasses\" style=\"color:#c8a84b\"\u003eAll Uvex Safety Glasses\u003c\/a\u003e  | \n    ANSI Z87.1 Compliance Guide\n  \u003c\/p\u003e\n\u003c\/div\u003e","brand":"Uvex","offers":[{"title":"Clear \/ Uvextra Anti-Fog","offer_id":44142841495640,"sku":"S4040","price":13.99,"currency_code":"USD","in_stock":true},{"title":"Gray \/ Uvextra Anti-Fog","offer_id":44142841528408,"sku":"S4041","price":13.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0594\/1900\/0920\/files\/31wab4pvfVL._SL500.jpg?v=1779745385","url":"https:\/\/wcsafety.com\/products\/uvex-tirade-safety-glasses","provider":"WC Safety","version":"1.0","type":"link"}
