OSHA 29 CFR 1910.133: Eye and Face Protection Requirements

OSHA’s eye and face protection requirements sit in 29 CFR 1910.133 and require every general-industry employer to provide appropriate protective eyewear, at no cost in most cases, whenever workers face flying particles, molten metal, chemical splashes, gases or vapors, or harmful light radiation. The employer picks the right gear based on a written hazard assessment, ensures it fits, trains workers on how to use it, and enforces consistent use on the job.

The Six Hazards That Trigger the Rule

Section 1910.133(a)(1) lists six hazard categories. If any are present, affected workers must wear appropriate eye or face protection:¹

Flying particles from grinding, chipping, woodworking, or machining
Molten metal from pouring, casting, or welding
Liquid chemicals that could splash toward the eyes
Acids or caustic liquids that damage tissue on contact
Chemical gases or vapors that irritate or injure the eyes
Harmful light radiation from welding arcs, lasers, or furnace work

If a task involves none of these, the standard does not require eye or face protection for it. Whether a job actually involves one of them is decided by the hazard assessment, not by assumption.

Written Hazard Assessment

Before choosing any protective eyewear, the employer must conduct a workplace hazard assessment under 29 CFR 1910.132(d). The assessment identifies hazards that are present or likely to be present, so the employer can choose the correct protection, communicate those choices to workers, and select gear that fits each person.²

The assessment has to be documented with a written certification identifying the workplace evaluated, the person who did the evaluation, the date, and a statement that the document is a hazard-assessment certification.³ Missing paperwork is a common citation trigger even when appropriate gear is actually in use. Right goggles on the shelf, no certification on file, still out of compliance.

Who Provides and Pays for the Protection

The duty runs to the employer, not the worker. The employer must ensure each affected employee uses the right eye or face protection whenever a listed hazard is present, and “ensure” means enforcing consistent use, not just handing out safety glasses on day one.¹

Under the PPE payment rule at 29 CFR 1910.132(h), the employer generally provides protective equipment at no cost and pays for replacements, unless the employee lost or intentionally damaged them. There is one meaningful exception for eyewear: the employer does not have to pay for non-specialty prescription safety glasses so long as the worker can wear them off the job.² “Non-specialty” is the key word. Basic prescription safety glasses that double as everyday eyewear fall into the exception. Specialty prescription eyewear built for a specific hazard, such as filter-lens prescription goggles for welding, does not.

Fit matters as much as availability. Safety glasses that slide down the nose or leave gaps at the temples defeat the purpose, and providing ill-fitting gear can produce a citation just as easily as providing none.

Side Shields, Marking, and ANSI Standards

When flying objects are a hazard, front-only lenses will not do. Section 1910.133(a)(2) requires side protection, either built into the frames or added as clip-on or slide-on shields that meet the same protective standards as the primary lenses.¹ Detachable shields must stay in place during an impact; if a side shield is lost or damaged, the assembly is out of compliance until it is replaced.

Every piece of protection must carry a manufacturer marking. Gear without one is noncompliant and should be pulled from service. Beyond that, the regulation incorporates three ANSI consensus standards, any one of which is acceptable:

ANSI/ISEA Z87.1-2010
ANSI Z87.1-2003
ANSI Z87.1-1989 (R-1998)

Compliant equipment carries a “Z87” mark on the lens or frame, with a “+” indicating high-impact testing. Other markings you may see include “D3” for splash protection, “D4” for dust, “W” plus a shade number for welding filters, and “Z87-2” for prescription safety lenses. OSHA has not incorporated the newer ANSI/ISEA Z87.1-2020 or Z87.1-2025 editions, so gear marked only to those newer editions sits in a gray area unless it also complies with one of the three listed versions.¹

Protection also has to be designed for disinfection and cleaning. Equipment that cannot be properly sanitized fails the minimum design requirement, which matters most when gear is shared across shifts. Scratched or pitted lenses that reduce visibility should be replaced.

Workers Who Wear Prescription Lenses

Workers who need corrective lenses have two options under 1910.133(a)(3): safety eyewear with the prescription built into the protective lenses, or protective goggles or a face shield worn over their everyday glasses.¹ The over-the-glasses setup must sit properly without shifting the prescription frames or pressing on the lenses.

Contact lenses are not eye protection and do not change the requirement for safety eyewear. OSHA specifically advises against contact lenses when working with acrylonitrile, methylene chloride, or ethylene oxide.⁴ Outside those substances, NIOSH guidance allows contact lens use with required safety eyewear on a case-by-case basis. A written workplace policy on contacts, informed by the hazard assessment, is the cleanest way to handle it.

Filter Lens Shades for Welding and Cutting

For operations that produce harmful light radiation, 1910.133 sets minimum filter-lens shade numbers. Using a shade below the listed minimum is both a violation and a real risk of permanent eye damage. The standard’s own practical guidance: start with a shade too dark to see the weld zone, then step down to a lighter shade that gives a clear view without going below the minimum.¹

Common minimums include:

Shielded metal arc welding: shade 7 under 60 amps, up to shade 11 above 250 amps
Gas metal arc (MIG) and flux cored arc welding: shade 7 below 60 amps, shade 10 at 60 amps and above
Gas tungsten arc welding (TIG): shade 8 below 150 amps, shade 10 for 150 to 500 amps
Plasma arc welding: shade 6 under 20 amps, up to shade 11 for 400 to 800 amps
Plasma arc cutting: shade 8 under 300 amps, shade 9 for 300 to 400, shade 10 above 400 (lighter filters may work when the workpiece hides the arc)
Gas welding: shade 4 light, shade 5 medium, shade 6 heavy (over 1/2-inch plate)
Oxygen cutting: shade 3 under 1 inch, shade 4 for 1 to 6 inches, shade 5 above 6 inches
Torch brazing: shade 3
Torch soldering: shade 2
Carbon arc welding: shade 14

For oxyfuel welding or cutting with a bright yellow flame, the standard recommends a filter that absorbs the yellow sodium line. The full table lives in the appendix to 1910.133 and is worth posting near welding stations.

One boundary: 1910.133 does not set selection criteria for laser radiation, even though harmful light radiation is one of the six triggering hazards. Laser eyewear selection depends on wavelength and power; employers using lasers need to work from ANSI Z136.1 and consult a laser safety officer rather than the shade table alone.

Training Every Worker Who Wears PPE

Under 29 CFR 1910.132(f), every employee required to wear PPE has to be trained on:⁵

When eye or face protection is necessary
What type is needed for each task
How to put it on, take it off, adjust it, and wear it correctly
The equipment’s limitations
Care, maintenance, useful life, and disposal

Each worker has to demonstrate understanding and correct use before doing work that requires the equipment. A signature on a sign-in sheet is not enough if the person cannot actually adjust their goggles.

Retraining is required whenever there is reason to believe the worker has lost the necessary knowledge or skill. Three specific triggers: workplace changes that make earlier training outdated, changes in the type of PPE used, or signs that a worker does not understand or is not properly using assigned protection.² The third one catches many employers off guard. If a supervisor sees a worker in a grinding area wearing safety glasses without side shields, the fix is not only correction in the moment; it is retraining.

Penalties for Violations

OSHA adjusts its civil penalty amounts each year for inflation. As of January 2025, the maximum for a serious violation is $16,550 per instance, and willful or repeated violations carry a maximum of $165,514 per citation.⁶ The 2026 figures will be somewhat higher once announced.

A single inspection can produce multiple citations. An employer with no written hazard assessment, no training documentation, and workers using unmarked safety glasses could face separate serious citations for each deficiency. The financial exposure adds up quickly, and that is before the cost of an actual eye injury, which will dwarf any fine OSHA can impose.
