KleenGuard Nemesis V30 Safety Glasses

The KleenGuard V30 Nemesis is the widest-spanning safety eyewear in the KleenGuard line, offering 18 distinct variants under one frame platform. The wraparound polycarbonate frame balances all-day comfort with genuine Z87.1+ impact protection, and the variant range stretches from a $6.09 standard clear lens for basic indoor use all the way to $29.00 premium polarized options for high-glare outdoor work. Workers who split their day between inside and outside tasks often choose the Nemesis I/O (Indoor-Outdoor mirror) variant, while crews in welding observation areas opt for the Shade 3 or Shade 5 tint. For workers who need an over-the-glasses fit for prescription eyewear, consider the Law OG1 OTG; for a minimalist two-variant model focused on anti-fog performance, the KleenGuard Maverick is a cleaner stocking choice.

Key Features

• 18 Variants, One Frame Platform — Stocking the Nemesis covers the widest range of jobsite conditions without introducing multiple frame SKUs into your inventory; lens tint is the only variable that changes between orders.
• ANSI/ISEA Z87.1+ High-Impact Rating — The "+" denotes high-velocity impact testing (1/4-inch steel ball at 150 fps), meeting or exceeding the threshold required under OSHA 1910.133 and 1926.102 for flying-particle hazard environments including grinding, chipping, and nailing.
• Anti-Fog Coating Option — Anti-fog variants (Clear AF, Gray AF, Amber AF, Clear AF/Camo, Gray AF/Camo, Amber AF/Camo) use a permanent bonded coating on the inner lens surface, reducing condensation when moving between temperature-controlled and outdoor environments — the primary failure mode for uncoated safety glasses in warehouse and roofing applications.
• Polarized Options for High-Glare Outdoor Work — The Polarized Gray ($28.39) and Polarized Brown ($29.00) variants use a multi-layer polarized filter that eliminates horizontal glare from water, pavement, and metal surfaces. Polarized lenses outperform mirror lenses in glare reduction for sustained outdoor exposure like landscaping, roofing, and marine work.
• Welding Observation Tints (Shade 3 and Shade 5) — The Shade 3.0 ($10.59) and Shade 5.0 ($11.79) variants are rated for welding area observation (not primary arc viewing). Shade 5 is appropriate for gas welding and light cutting operations where a worker is in the vicinity but not the primary operator.
• Wraparound Fit with Extended Peripheral Coverage — The sport-wrap frame geometry reduces the gap between lens edge and face compared to flat-lens rectangular frames, lowering the risk of debris entry from the side — relevant for grinding, sawing, and high-wind outdoor tasks.

Available Tints & Coatings

All lenses are polycarbonate with UV400 protection. Select the tint by primary work environment.

Applications

• Construction and Roofing — Gray AF or Smoke Mirror for outdoor sun; Clear AF for interior framing where workers move between conditioned and unconditioned spaces throughout the day.
• Manufacturing and Assembly — Clear standard or Clear AF is the default choice for production floors with overhead fluorescent lighting; anti-fog is essential near autoclaves, wash stations, or temperature-controlled clean rooms.
• Welding and Fabrication Areas — Shade 3 for gas welding bystanders and welding helpers; Shade 5 for light cutting and gas welding operators. Neither shade is appropriate for arc welding primary operators (requires a welding helmet).
• Outdoor and Landscaping Work — Polarized Gray or Polarized Brown for crews with sustained sun exposure across an 8-hour shift; Blue Mirror or Smoke Mirror for tasks with intermittent shade.
• Automotive and Chemical Plants — Clear standard or Clear AF; the wraparound geometry provides better side-debris protection than flat-lens glasses during undercar work and fluid handling in confined spaces.
• Warehousing and Dock Operations — Indoor-Outdoor Mirror (I/O) is purpose-built for workers who repeatedly step from a dark warehouse onto a bright loading dock; eliminates the need to swap glasses between environments.

ANSI Z87.1+ Compliance

The KleenGuard V30 Nemesis carries the ANSI/ISEA Z87.1+ marking, which indicates the lens passed the high-velocity impact test: a 1/4-inch (6.35 mm) steel ball fired at 150 feet per second. This is the "+" suffix on the Z87.1 standard — base Z87.1 covers basic impact from slower projectiles, while Z87.1+ covers the higher-velocity debris produced by grinders, nail guns, and high-speed cutting tools. OSHA 29 CFR 1910.133 (general industry) and 1926.102 (construction) require employers to provide appropriate eye protection whenever flying particles, molten metal, liquid chemicals, acids, caustic liquids, chemical gases, vapors, or radiation hazards are present. For most industrial applications, Z87.1+ is the minimum acceptable marking.

Polycarbonate is the lens material of choice for Z87.1+ compliance because it is inherently impact-resistant at a material level — not because of a coating or treatment — making it significantly more impact-resistant than glass or CR-39 plastic. All KleenGuard V30 Nemesis variants use polycarbonate lenses and provide 99%+ UV protection across all tints, including the clear lens.
