Ensure total electrical safety when working near energized equipment with our non-conductive, metal-free prescription safety glasses. Electricians, high-voltage linespeople, and utility technicians face severe risks from arc flashes and electrical grounding if their gear contains metallic components. Our dielectric safety specs are manufactured entirely from non-conductive polymers, containing zero metal screws, hinges, or core wires.
Designed to comply fully with UK BS EN166 industrial standards, these non-conductive frames eliminate the risk of electrical current transfer while delivering impact defense against electrical arcing particles and debris. Fitted with custom shatterproof prescription lenses, our dielectric collection provides safety and optical precision on every job. Explore our options below.

Non-Conductive / Metal-Free Safety Glasses
Working on live electrical panels, high-voltage distribution networks, or electronic assembly lines requires specialized PPE. Standard metal frames or plastic frames with internal wire cores or metal hinges can act as electrical conductors, increasing the risk of arc flash injuries. Our dielectric safety glasses replace metal fasteners with heavy-duty polymer pin hinges and nylon hardware to eliminate electrical conductivity.
In addition to dielectric safety, these frames are designed to withstand physical impacts from arc blast fragments and flying debris. Made from high-density nylon and TR90 composites, dielectric safety frames provide structural resilience without sacrificing flexibility or adding unnecessary weight, remaining comfortable throughout long service calls.
Custom-fitted with impact-resistant Polycarbonate or Trivex lenses, our non-conductive safety glasses accommodate single vision, bifocal, and progressive varifocal prescriptions. Upgrade your specs with permanent anti-fog coatings to keep vision clear when working in warm electrical closets or wearing arc flash face shields.

Frequently Asked Questions: Non-Conductive / Metal-Free Safety Glasses
1. What makes safety glasses non-conductive (dielectric)?
Non-conductive safety glasses are manufactured without any metal hardware, screws, or internal core wires, preventing electrical conductivity near live currents.
2. Who should wear non-conductive prescription safety glasses?
Electricians, utility workers, high-voltage engineers, and electronics technicians who work near energized circuits or high-voltage equipment should wear non-conductive eyewear.
3. Are metal-free safety frames as durable as traditional metal frames?
Yes. Dielectric frames use advanced high-density nylon polymers and TR90 composites that pass identical BS EN166 mechanical impact tests.
4. Can I wear dielectric safety glasses underneath an arc flash visor?
Yes, our low-profile dielectric frames are designed to sit comfortably underneath arc flash hoods and visors without slipping or causing pressure points.
5. Can I get varifocal lenses in metal-free dielectric safety glasses?
Yes, we fit single vision, bifocal, and progressive varifocal prescription lenses directly into our non-conductive dielectric safety frames.
