Engineered with a flexible over-the-glasses (OTG) chassis, these goggles accommodate prescription eyewear without compromising the sealed fit, making them a practical upgrade from conventional \u003ca href=\"\/collections\/safety-glasses\"\u003esafety glasses\u003c\/a\u003e in environments that demand dust and splash protection. Available in clear (60479) and gray tint (60480) lens configurations, they represent Klein Tools' commitment to Optical Class-1 clarity across its \u003ca href=\"\/collections\/eye-protection\"\u003eeye protection\u003c\/a\u003e lineup.\u003c\/p\u003e\n\n\u003ch2\u003eConstruction and Design\u003c\/h2\u003e\n\u003cp\u003eBoth models share an identical black-and-orange polycarbonate frame with a soft inner rim that seals against the face without requiring a separate foam gasket. The wraparound nine-base curvature provides peripheral coverage, and the flexible temples are interchangeable with an included headband for secure positioning during high-activity tasks. The frame is lightweight and compact enough to fit under most hard hat brims.\u003c\/p\u003e\n\n\u003ch2\u003eCompliance and Certifications\u003c\/h2\u003e\n\u003cp\u003eThe Klein Tools 60479 and 60480 are certified to ANSI Z87.1+ (2020) and CSA Z94.3-20 for high-velocity impact, and to MIL-PRF-32432A Class 2 for ballistic fragmentation — a level of certification rare among general-purpose industrial goggles. Both models carry ANSI Z87.1-D3 (droplet and splash) and ANSI Z87.1-D4 (dust) ratings, qualifying them for chemical splash environments where unrated goggles fail compliance review. UV protection is integral to the lens material.\u003c\/p\u003e\n\n\u003ch2\u003ePerformance Assessment\u003c\/h2\u003e\n\u003cp\u003eFour independently adjustable vents distinguish these goggles from fixed-seal designs. Each vent can be opened for cross-ventilation during moderate-exertion tasks or closed individually to eliminate particulate pathways in high-dust environments. The anti-fog coating maintains optical clarity under humidity and temperature differentials that would compromise uncoated lenses within minutes. In practice, the OTG fit is functional with most standard prescription frames up to medium temple width; oversized frames may reduce the peripheral seal.\u003c\/p\u003e\n\u003cp\u003eThe gray-tint 60480 carries an 85% visible light transmission rate, suitable for outdoor work in bright conditions but less appropriate for dim interiors or low-light overhead tasks. The clear 60479 maintains near-full transmission and is the correct selection for indoor industrial use.\u003c\/p\u003e\n\n\u003ch2\u003eStrengths\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eMilitary-grade ballistics certification (MIL-PRF-32432A) — uncommon at this price tier\u003c\/li\u003e\n  \u003cli\u003eFour independently adjustable vents provide genuine ventilation control\u003c\/li\u003e\n  \u003cli\u003eOTG design verified to accommodate prescription eyewear\u003c\/li\u003e\n  \u003cli\u003eOptical Class-1 lens minimizes distortion across the full field of view\u003c\/li\u003e\n  \u003cli\u003eDual dust (D4) and splash (D3) ratings satisfy most chemical-handling compliance requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eLimitations\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eNo dielectric rating — not appropriate as primary protection for live electrical work above low voltage\u003c\/li\u003e\n  \u003cli\u003eGray tint (60480) reduces light transmission, limiting utility in low-light conditions\u003c\/li\u003e\n  \u003cli\u003eVent design, while adjustable, does not achieve the fine-mist chemical splash protection of a fully sealed indirect-vent goggle\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eRecommended Use Cases\u003c\/h2\u003e\n\u003cp\u003eThe 60479 and 60480 are well suited for grinding, cutting, demolition, overhead fastening, woodworking, concrete work, and any dust-generating task where standard safety glasses provide insufficient coverage. The 60480 gray-tint variant is the preferred selection for outdoor construction, roofing, and landscaping. Both models meet the sealed-eyewear standard required by many industrial hygiene programs and OSHA 1910.133 compliance reviews.

The military ballistics certification and dual ANSI dust\/splash ratings place these above most residential-grade goggles. Prescription-eyewear users who cannot wear traditional goggles over their frames will find the OTG design particularly practical. Buyers needing indirect-vent chemical splash protection or full dielectric certification should evaluate purpose-built chemical-splash goggles for those applications.\u003c\/p\u003e","brand":"Klein Tools","offers":[{"title":"Clear","offer_id":44133756764248,"sku":"60479","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Gray","offer_id":44133756797016,"sku":"60480","price":22.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0594\/1900\/0920\/files\/41HAg5aRvkL._SL500.jpg?v=1779508436","url":"https:\/\/wcsafety.com\/products\/klein-tools-safety-goggles-60479-60480-otg-anti-fog","provider":"WC Safety","version":"1.0","type":"link"}
