Eye Hazards in Welding: What You’re Protecting Against
Welding is one of the most eye-hazardous occupations in any industrial setting. The hazards are multiple, intense, and operate simultaneously. Understanding exactly what threatens welders’ eyes is the starting point for choosing appropriate protection.
UV and Infrared Radiation — The Invisible Threat
The electric arc created in arc welding processes (MIG, TIG, stick welding) generates intense ultraviolet and infrared radiation. UV radiation can cause photokeratitis — essentially a sunburn of the cornea — in as little as a few seconds of unprotected exposure. This condition, commonly called “arc eye” or “welder’s flash,” is intensely painful and debilitating, though usually temporary.
Repeated episodes of arc eye, or chronic low-level UV exposure, can lead to more serious long-term eye conditions. The cornea does not develop immunity to UV damage — every exposure is harmful.
Infrared radiation from the intense heat of welding operations can cause heat damage to the lens of the eye with cumulative exposure over a career.
Sparks and Spatter
Welding processes generate sparks and molten metal spatter that travel at high velocity from the weld point. These particles cool rapidly but retain enough heat and kinetic energy to cause serious burns and lacerations on impact with the eye.
Grinding operations associated with weld preparation and finishing add high-velocity metallic particles to this hazard environment.
Chemical Fumes and Flux
Welding fluxes, coatings, and base metals release chemical vapors and particulates. While primarily a respiratory concern, eye exposure to welding fumes can cause irritation and chemical exposure.
Physical Debris
The work environment around welding operations typically includes metal filings, wire offcuts, grinding dust, and scale that can enter the eye and cause abrasion or penetrating injury.
The Right Eye Protection for Welding
Welding eye protection requirements depend on the welding process and intensity. The key consideration is shade number — the darkness of the filter lens that reduces visible light and blocks radiation.
Shade Requirements by Process
- Gas welding (light): Shade 4-5
- Gas welding (medium/heavy): Shade 5-6
- MIG welding (light): Shade 7-8
- MIG welding (heavy): Shade 10-12
- TIG welding: Shade 8-10
- Stick welding: Shade 8-12 depending on amperage
- Plasma cutting: Shade 8-10
- Grinding only (no arc): Clear or light tint ANSI Z87.1 safety glasses
ANSI Z87.1 Compliance for Welding
Safety glasses and welding shields for use in welding environments must meet ANSI Z87.1 standards. This ensures they can withstand the impact of sparks and spatter, provide adequate optical protection, and meet the coverage requirements for the welding environment.
When purchasing safety glasses for a welding environment, look for the ANSI Z87.1+ marking on lenses and frames — this indicates high-impact certification suitable for welding environments.
Safety Glasses with Power for Welders Who Need Vision Correction
Many experienced welders require vision correction. A welder working with magnified detail, reading measuring instruments, or performing precision weld inspection cannot work effectively without clear vision. Safety glasses with power in appropriate shade configurations allow welders who need vision correction to work safely and accurately.
For welders requiring vision correction:
- Safety glasses with power in tinted/shade configurations are available
- Anti-fog coating is especially important given the heat of welding environments
- Side protection is critical for the high-spark environment around welding operations

Welding Eye Protection Beyond the Arc
Protection doesn’t stop when the arc is extinguished. The work environment around welding operations creates ongoing eye hazards:
Grinding and Deburring High-speed angle grinding generates metallic particles at much higher velocities than most people realize. Clear ANSI Z87.1 safety glasses are the minimum requirement for grinding operations.
Material Handling Moving, cutting, and fitting metal stock creates sharp edge, scale, and fibre hazards. Eye protection should be worn throughout the working day in a welding environment, not only during active welding.
Inspection Weld inspectors working in active welding areas need appropriate shade protection even when not welding themselves — the arc radiation from nearby operations is still hazardous.
Bulk Ordering for Welding Operations
Welding operations that employ multiple welders need to maintain adequate stocks of shade-appropriate safety glasses and welding shields. Safety glasses for grinding and prep work need to be available for all workers in the welding area.

Don’t Risk Your Vision
Welders have some of the highest rates of occupational eye injury in any industry. The good news is that nearly all of these injuries are preventable with appropriate eye protection. The bad news is that the damage from arc eye and UV exposure accumulates over a career — and may not be fully apparent until significant harm has already been done.
