EXTREMELY COMFORTABLE, ERGONOMIC FRAME — The soft rubber seal molds to your face. The adjustable elastic band helps you get the fit just right. And that’s not all: these comfy splash proof goggles for chemistry have a secret. You can turn these safety goggles for chemistry lab into glasses by swapping the headband for the arms! VANGUARD PLUS ANTI FOG COATING — This K&N certified lens treatment increases fog resistance by 5x and scratch resistance by 2x, compared to the EN166 standard.

WIDE ANGLE, WRAPAROUND CLEAR LENSES — The tough, impact resistant polycarbonate lenses help you see clearly and reduce optical distortion. That’s why these lab glasses chemistry are a go-to for nurses, medical and healthcare workers, lab and dental workers, and school students taking biology, science or chemistry class. ANSI Z87.1 CERTIFIED — Looking for dust goggles that looks great on men and women? You’ve found it! These lab goggles for women are great for construction, metal grinding, manufacturing, mowing, cutting trees, or weed whacking. But remember: these ppe goggles don’t fit over prescription glasses.

Swap out the comfortable headband for the fully adjustable arms whenever you need glasses. And then swap things right back. (Quick note: because they’re both goggles and glasses, this pair is a little heavier than traditional glasses and doesn’t fit over prescription glasses.) Thanks to the Vanguard PLUS treatment, these chemistry lab goggles won’t fog up. We coated both sides of these safety googles with Vanguard PLUS so you can enjoy 5x higher fog resistance than standard glasses, 2x higher abrasion resistance than the EN166 norm and complete UV protection. Help the coating last longer by storing the lab googles in a protective case and avoiding abrasive cleaning materials. Get serious onion goggles you can wear all day long. The polycarbonate lenses protect your eyes against high speed particles at extreme temperatures. When you use them as goggles, the indirect vents keep drops and dust away from your face. And when you use them as chem goggles, the adjustable SoftPad frames feel great on. You can even pair these D3 compliant goggles with a mask or respirator. Let air in and keep dust out thanks to clever indirect venting with these saftey goggles. The sophisticated ventilation works by adding angled vents that face away from the front of the face. This keeps debris away and lets air circulate so you stay comfortable all day long. If you switch temperatures fast, your z87 safety goggles may mist up a little. If that happens, re-adjust the band.
