DEWALT DPG109 Polarized Safety Glasses

The DEWALT DPG109 combines two features you rarely see together in a half-frame safety glass: polarized lenses that cut horizontal glare off pavement, water, and reflective surfaces, and a rubberized brow guard that closes the gap above the lens where most safety glasses leave debris a path straight to your eyes. The over-molded rubber temples flex to fit a wide range of head shapes and stay put during active movement — no constant readjusting under a hard hat. Compare it to the entry-level DEWALT DPG100T Crosscut if you don't need polarized; see our full safety glasses collection for all options.

Key Features

• Polarized Smoke Lenses — Eliminates horizontal glare off pavement, standing water, and reflective job-site surfaces; improves depth perception and contrast outdoors in a way standard tinted lenses cannot.
• Rubberized Brow Guard — Closes the upper lens gap that standard open-frame glasses leave open; keeps sawdust, concrete chips, and overhead debris from reaching your eyes from above.
• Super-Flexible Over-Molded Rubber Temples — Flex to accommodate a wide range of head widths; grip holds under hard hats, bump caps, and helmets without leaving pressure marks during extended wear.
• Anti-Slip Rubber Nosepiece — Maintains position when you look down, bend over, or sweat — critical for overhead work or active site movement.
• ANSI/ISEA Z87.1-2020 Compliant — High-impact rated for use in OSHA-regulated environments involving flying-particle hazards.
• 99.9% UV Protection — Blocks UV-A and UV-B; important for full-day outdoor work where cumulative UV exposure is a real risk.

Why Polarized Lenses on Safety Glasses?

Standard smoke or gray tinted safety glasses reduce overall light but do nothing about horizontal glare — the flat, bright reflections that bounce off pavement, puddles, vehicle hoods, and glass panels at eye level. Polarized lenses contain a chemical filter oriented to block that specific horizontal polarization. On a bright construction site or road work zone, the difference is substantial: you see contrast clearly instead of squinting against wash-out. For indoor work, polarized is unnecessary (there's no directional glare from overhead fluorescent lighting), which is why we also carry the non-polarized DPG100T Crosscut for mixed indoor/outdoor use.

Applications

• Outdoor Construction & Site Work — Polarized lens and brow guard combination handles the two biggest outdoor hazards: glare and overhead debris.
• Road Work & Traffic Control — Polarized lenses cut glare off pavement and passing vehicles; brow guard stops chips from overhead passes.
• Roofing — UV protection and polarized smoke lens for full-day sun exposure; rubber temples hold secure when looking down the pitch.
• Landscaping & Grounds Maintenance — Brow guard keeps grass clippings and mulch out; rubber nosepiece holds during bending and overhead trimming.
• Automotive Exterior Work — Cuts glare off vehicle panels and glass; brow guard stops debris from hood-up work.
• Marine & Waterside Work — Polarized lenses designed specifically for water-surface glare; UV protection for full-day sun exposure near reflective water.

ANSI Z87.1 Compliance

The DEWALT DPG109 is marked ANSI/ISEA Z87.1-2020 for high-impact eye protection. This standard covers impact resistance (high-mass and high-velocity tests), optical quality (lens distortion must fall within specified limits), and UV transmittance (UV-A and UV-B must be blocked). The 99.9% UV protection claim is tested and standardized under this certification, not a marketing estimate. The polycarbonate lens material is inherently impact resistant, and the polarizing filter is applied as a laminated layer that does not compromise the structural impact performance of the lens.

Under OSHA 29 CFR 1910.133 (general industry) and OSHA 1926.102 (construction), employers must provide eye protection rated for identified hazards. For outdoor work with flying-particle risk, the DPG109 satisfies both. The rubberized brow guard — while not a goggle-style seal — provides meaningful additional protection from above-eye debris that unguarded frames cannot offer. For full chemical splash protection, a sealed safety goggle is the correct choice.
