Electrical Safety Glasses: Non-Conductive ANSI Z87+ Eyewear for Electricians
Energized conductors, flying debris, and arc-flash all live on an electrical job. Here is what OSHA 1910.133 and 1910.335 require, why your frame should be non-conductive, and where NFPA 70E arc-flash protection layers on top.
Shop ANSI-rated safety glasses →We have supplied prescription and non-prescription safety eyewear to electrical crews for years, and the electrical trade has one requirement most industries do not: the frame itself can be part of the hazard. Metal hardware near an energized conductor is a path for current, which is why electrical eye protection starts with a non-conductive frame and a polycarbonate lens. OSHA 1910.133 sets the general eye and face protection rule, OSHA 1910.335 requires eye and face protection wherever there is danger from electric arcs, flashes, or flying objects from an electrical explosion, and ANSI/ISEA Z87.1 is the technical spec the protection has to meet. This guide covers the hazards, the non-conductive build, how arc-flash protection works under NFPA 70E, and the prescription options for electricians who wear a correction.
The eye hazards electricians actually face
Electrical work mixes the ordinary jobsite hazards with two that are specific to the trade: current through conductive eyewear, and the thermal energy of an arc-flash event. Knowing which ones you face decides the frame, the lens, and whether you need face protection over your glasses.
- Energized conductors near metal frames — metal hinges, screws, and temple cores near live parts can carry current; non-conductive frames remove that path.
- Arc-flash and arc-blast — an arc-flash releases intense heat, light, and pressure; thermoplastic frames can melt, so frame material and arc-rated face protection both matter.
- Flying particles and debris — conduit cutting, knockouts, drilling into masonry and concrete, and fish-tape work throw fragments.
- Optical radiation and glare — bright arcs, plus UV and glare on outdoor line and solar work.
- Dust and fine particulate — drywall, masonry, and ceiling-cavity dust during rough-in and service work.
Buyers often think “non-conductive” means a plastic-looking frame, but a frame can read as plastic and still carry metal hinge pins, nose-pad screws, or a metal temple core. OSHA’s electrical work-practice rule (1910.335) treats conductive eyewear like other conductive articles near energized parts. For energized work, a truly non-conductive frame has zero metal hardware anywhere in the structure, paired with a polycarbonate lens that is non-conductive by nature.
What OSHA and NFPA 70E require for electrical eye protection
Electrical eye protection sits under more than one rule, and they stack rather than compete:
- OSHA 1910.133 — the general industry eye and face protection standard; protection has to meet ANSI Z87.1, with the Z87 or Z87+ mark on the lens and frame.
- OSHA 1910.335 — the electrical safe-work-practices rule; requires eye and face protection wherever there is danger of injury from electric arcs, flashes, or flying objects from an electrical explosion, and restricts conductive articles near energized parts.
- NFPA 70E — the consensus electrical-safety standard most contractors work under; it sets the arc-flash hazard assessment and the arc-rated PPE that follows from it.
- ANSI/ISEA Z87.1 — the technical eye-protection spec all of the above reference; Z87+ is the high-impact mark you want for cutting, drilling, and knockout work.
What is specific to the electrical trade is the added expectation that frames used near energized conductors are non-conductive. There is no separate cert mark for “non-conductive” on most frames; it is verified through the maker’s material and construction (a metal-free chassis), which is why the frame’s build matters as much as its Z87+ mark.
For energized or potentially energized work, start with a non-conductive Z87+ frame. If the task crosses an arc-flash boundary, the arc-rated face shield or hood from your site’s arc-flash assessment is the primary face protection, and your Z87+ glasses go underneath as the primary eye protection, not the other way around.
What a non-conductive frame actually means
A non-conductive safety frame has no metal hardware anywhere in the frame structure. That is a stricter requirement than it sounds, because metal turns up in places buyers do not check:
- Hinge pins — the most common spot where metal hides in an otherwise plastic frame.
- Nose-pad screws — often metal even on frames marketed as plastic.
- Temple cores — some industrial frames run a wire core through the temple arm for stiffness.
- Logo plates and reinforcement — metal decorative inlays or eyewire reinforcement.
Combine a fully non-conductive frame with a polycarbonate lens (which is non-conductive on its own) and the whole pair is electrically isolated, so the eyewear is not a conduit for current. For service troubleshooting, equipment work, and switchgear access that occasionally crosses into energized conditions, the non-conductive build is the baseline. If a non-conductive frame is visibly cracked or damaged to the point that internal structure is exposed, retire it; damaged eyewear also no longer meets Z87.1.
Arc-flash: where NFPA 70E layers on top of non-conductive
Non-conductive construction handles the electrical-isolation case. It does not, by itself, handle an arc-flash event, which is a different hazard: intense heat, light, and pressure released in a fraction of a second. NFPA 70E is the standard that governs it, and the order of protection is the part crews most often get wrong.
Standard ANSI Z87.1 safety glasses carry impact certification; they are not arc-rated, and “arc-flash safety glasses” is not really a product category. For arc-flash work, NFPA 70E calls for an arc-rated face shield or an arc-flash hood, selected for the calculated incident energy at the working distance per your facility’s arc-flash study. That face shield or hood is the primary face protection. Under it, you still wear ANSI Z87+ safety glasses (or goggles) as the primary eye protection, because a face shield is a secondary device and does not replace the glasses underneath. Higher-energy work uses a full arc-rated hood that integrates the face protection.
Z87+ glasses alone are not arc-flash protection. For any task inside an arc-flash boundary, the arc-rated face shield or hood specified by your site’s arc-flash hazard and incident-energy assessment is required, with Z87+ glasses worn underneath. Frame material matters too: thermoplastic frames can melt in an arc event, so verify the combination against your facility’s arc-flash study before approving it.
Recommended protection by electrical work type
The right setup depends on the work and its arc-flash exposure. Match the eyewear to the task in front of you.
Coatings and lenses that earn their keep
A few options make the difference between glasses electricians wear all shift and glasses that end up on the hard hat:
- Anti-fog — the one most crews want, for warm panel rooms, attic and ceiling-cavity work, and cold-weather line work. Look for the X mark, or shop our anti-fog safety glasses.
- Anti-scratch (hardcoat) — a hardened surface that holds up to dust and grit; it does not make a lens scratch-proof, but it buys real life on the job.
- UV tint — for outdoor line and solar work, a tinted lens with UV protection (the U-scale mark) that still meets Z87+.
- Polarized — cuts glare on outdoor work, with one caveat: polarized lenses can wash out LCD screens, so techs reading meters and equipment displays may prefer a plain tint.
Prescription safety glasses for electricians
If you wear a correction, you can meet the requirement two ways: prescription lenses built into a rated frame (marked Z87-2 or Z87-2+), or compliant over-the-glasses (OTG) protectors worn over your everyday glasses. For an all-shift fit, built-in prescription lenses are usually the better call, and for electrical work the frame should be non-conductive. At SafetyGearPro, your prescription is cut in our U.S. optical lab and checked by our team before production, with high-index lenses for stronger prescriptions to keep them light. Prescription safety glasses are FSA/HSA eligible, ship free over $99, and typically take about 10 business days to make. Start with ANSI prescription safety glasses, or browse the full prescription safety eyeglasses range and filter for non-conductive frames.
Inspection, care, and the non-conductive damage trigger
Inspect every shift for cracks, pitting, scratches, or loose side shields, and clean with mild soap and water rather than dry-wiping a dusty lens, which drags grit across it and scratches it. Replace a lens the moment it is cracked, pitted, or badly scratched; a damaged lens no longer meets the standard. Electrical work adds one inspection point other trades do not have: damage to the non-conductive frame material that exposes internal structure, or a crack in the chassis or hinge that could create a metal-exposure path, means the frame is no longer fully non-conductive. Retire it right away, even if the lens itself is intact.

Frequently asked questions
What does OSHA require for electrical eye protection?
OSHA 1910.133 is the general eye and face protection rule, and protection has to meet ANSI Z87.1. For electrical work specifically, OSHA 1910.335 requires eye and face protection wherever there is danger of injury from electric arcs, flashes, or flying objects from an electrical explosion. Most contractors also work under NFPA 70E, which sets the arc-flash hazard assessment and the arc-rated PPE that follows.
What does a non-conductive safety frame actually mean?
It means zero metal hardware anywhere in the frame: no metal hinge pins, no metal nose-pad screws, no metal temple cores, and no metal logo plates or reinforcement. Paired with a polycarbonate lens, which is non-conductive on its own, the whole pair is electrically isolated, so the eyewear is not a path for current near energized conductors.
Are non-conductive Z87+ glasses enough for arc-flash work?
No. Non-conductive construction handles electrical isolation, not the thermal energy of an arc-flash event. Standard ANSI Z87.1 glasses are not arc-rated. For arc-flash work, NFPA 70E calls for an arc-rated face shield or hood selected for the calculated incident energy per your site’s arc-flash study, with Z87+ glasses worn underneath. Verify the frame and face protection combination against your facility’s arc-flash assessment.
Do safety glasses replace an arc-rated face shield?
No. For arc-flash tasks the arc-rated face shield or hood is the primary face protection. Safety glasses are a primary eye-protection device worn underneath it; a face shield is a secondary device and does not cover the eyes on its own. You wear both, never the glasses instead of the shield.
Can I wear metal-frame glasses for electrical work?
Not for energized or potentially energized work. OSHA’s electrical work-practice rule treats conductive eyewear like other conductive articles near energized parts. Use a fully non-conductive frame with no metal hardware. Metal-frame industrial styles are fine for non-electrical use but defeat the non-conductive requirement near live parts.
Can I use my regular prescription glasses on an electrical job?
No. Standard prescription eyewear is not impact-rated. You need prescription safety lenses marked Z87-2 or Z87-2+ in a rated frame, ideally a non-conductive one for electrical work, or compliant over-the-glasses (OTG) protectors worn over your everyday glasses.
Do prescription safety glasses come in non-conductive frames?
Yes. Many industrial prescription frames use non-metal materials such as polyamide and are non-conductive by default. When you choose a prescription frame for electrical work, confirm it is fully non-conductive and Z87-2 or Z87-2+ rated. Our team can help match a non-conductive frame to your prescription.
What about low-voltage and telecom work?
Low-voltage installation such as data, telecom, fire alarm, and building automation does not usually involve arc-flash boundaries, so non-conductive frames are not strictly required, though they are good practice. The bigger need is clear, lightweight, comfortable frames for close-detail and overhead cable work, with anti-fog for warm spaces.
When should non-conductive electrical eyewear be replaced?
Replace immediately for any scratch, crack, or pitting that affects optical clarity, since a damaged lens is no longer ANSI-rated. Electrical work adds one more trigger: damage to the non-conductive frame material that exposes internal structure, or a crack in the chassis or hinge that could create a metal-exposure path, means the frame is no longer fully non-conductive. Retire it even if the lens is intact.
Do you handle bulk and GSA orders for electrical contractors?
Yes. We provide compliance documentation, bulk pricing, and GSA-friendly processes for electrical contractors, utilities, and corporate safety programs, including non-conductive frame catalogs and program structures with damage-replacement workflows.
For safety managers and electrical crews
Outfitting an electrical crew is a program, not a one-off purchase. OSHA requires a written hazard assessment before assigning PPE (29 CFR 1910.132), and for arc-flash exposure your facility’s arc-flash study drives the face protection you specify. NIOSH publishes free guidance on electrical safety that pairs well with a toolbox talk. For volume or government work, we handle bulk pricing, non-conductive frame catalogs, compliance documentation, and GSA purchasing through our corporate safety program.
