Garage and Workshop — FAQ
What does ANSI Z87.1 certification actually mean?
ANSI Z87.1 is the American National Standard for occupational eye protection. It means the glasses passed high-velocity impact tests (6.35mm steel ball at 150 fps), penetration tests, and optical clarity requirements. Always look for the Z87+ marking on the frame—it's your proof of legitimate testing, not just manufacturer claims.
Can I wear safety glasses over my prescription glasses?
Most standard safety glasses don't accommodate prescription frames comfortably. Look for OTG (Over-The-Glass) designs with deeper temples and wider frames. The DEWALT goggle we tested fits most prescription glasses underneath, but dedicated prescription safety glasses or inserts provide better comfort and seal.
How long do anti-fog coatings typically last?
Premium permanent coatings last 1-2 years with proper care. Avoid wiping with abrasive materials or harsh chemicals. Wash with mild soap and water, then air dry. Temporary spray-on anti-fog treatments last days to weeks. Our winner's coating survived 500+ cleaning cycles in testing with minimal degradation.
Are clear lenses suitable for outdoor work?
Yes, if they have proper UV protection. UV blocking is independent of tint—many clear lenses block 99.9% of UV rays. For bright sunlight, consider tinted or polarized lenses to reduce glare and eye strain. The Bullhead Pompano we tested excels at transitioning between indoor and outdoor environments.
What's the difference between safety glasses and safety goggles?
Glasses provide impact protection but allow airflow around the edges. Goggles create a sealed barrier against dust, liquids, and chemical splashes. Use glasses for general impact hazards (woodworking, grinding). Choose goggles for chemical handling, dusty environments, or infectious material exposure. The DEWALT DPG82-11 is our top goggle pick.
How do I prevent scratching my safety glasses?
Store glasses in a microfiber pouch or hard case when not in use. Clean with lens cleaning solution and microfiber cloth—never use paper towels or your shirt. Avoid setting lenses face-down on surfaces. Rinse off debris before wiping to prevent grinding particles into the coating. Our scratch test winner was the NoCry with its hardened polycarbonate.
