Garage and Workshop — FAQ
What does ANSI Z87.1 certification actually guarantee?
ANSI Z87.1 means the glasses passed high-mass (500g drop) and high-velocity (150 fps projectile) impact tests. The Z87.1+ rating indicates even higher impact resistance for industrial grinding and cutting operations. Always check for the Z87 marking molded into the lens itself.
Can I wear safety glasses over my prescription eyewear?
Most safety glasses fit over slim prescription frames, but it creates pressure points and gaps. For regular use, order prescription safety glasses or choose OTG (Over the Glasses) specific models. Our top pick accommodates most frames under 140mm wide.
How long do anti-fog coatings typically last?
Premium anti-fog coatings last 6-12 months with proper care—clean only with microfiber cloths and avoid harsh chemicals. Wiping with paper towels or shirt sleeves degrades the coating within weeks. Replacement lenses are often cheaper than new glasses.
Are tinted safety glasses suitable for indoor work?
Only use tinted lenses indoors if the environment is extremely bright (e.g., welding screens nearby). Most indoor work requires clear lenses for maximum light transmission and color accuracy. Tinted lenses reduce visual acuity in normal indoor lighting.
What's the difference between safety glasses and safety goggles?
Safety glasses provide impact protection with ventilation gaps. Safety goggles create a full seal against chemical splash and dust. Use glasses for impact hazards; goggles are mandatory for chemical handling and fine particulate environments like powder coating.
How should I clean my safety glasses without damaging them?
Rinse with lukewarm water to remove debris, then clean with mild soap and microfiber cloth. Avoid ammonia-based cleaners, paper towels, and alcohol wipes—they destroy anti-fog coatings and scratch polycarbonate. Store in a hard case when not in use.
