Even when you can’t see the sun, the indoors can be brighter than you might think. Bright overhead LED bay lights, reflective metal surfaces, and computer screens can make indoor industrial environments glaringly intense, which might lead some workers to reach for tinted or dark safety glasses.
But does OSHA allow tinted safety glasses indoors, or would wearing these cause your workplace to fail an inspection? Although the agency doesn’t specifically ban tinted safety glasses indoors, OSHA standard 29 CFR 1910.133(a)(1) requires every worker’s personal protective equipment (PPE) to match the specific workplace hazards they face. And if wearing darkened lenses indoors creates secondary hazards, such as poor visibility or altered color perception, it becomes an OSHA violation.
Read on for a breakdown of OSHA’s indoor tinted safety glasses rules, the risks of wearing dark lenses indoors, and recommended compliant solutions for indoor glare protection.
DECODING STANDARD 1910.133
The Occupational Safety and Health Administration (OSHA) is a federal agency of the United States Department of Labor that sets and enforces workplace health and safety standards. OSHA 1910.133 requires employers to ensure workers use eye or face protection that’s appropriate for the specific hazards present, such as impacts, dust, splashes, or radiation.
The agency clarifies in several official letters of interpretation that although no blanket OSHA tinted-glasses regulation exists for indoor work, employers must conduct a hazard assessment to evaluate the worksite and identify the specific chemical and physical hazards present.
To be compliant for indoor use, tinted safety glasses must meet three specific criteria:
The lenses must comply with ANSI/ISEA Z87.1 safety standards and feature the appropriate safety markings.
Employers must assess workplace hazards and ensure that the selected tint does not dangerously restrict employees’ vision or interfere with their tasks.
Photochromic lenses must not create visibility hazards when workers move between areas with different lighting conditions.
Essentially, if dark tints impede a worker’s ability to see hazards, machinery controls, or color-coded safety warnings, you must prohibit them in those specific indoor areas.
WHY INSPECTORS TAKE NOTICE
Dark tints affect how the eyes process light transmission, contrast, color, depth, and glare. The following are the specific dangers workers face while wearing dark-tinted lenses.
Dark sunglasses tints drastically reduce the amount of light entering the eye, causing retinas to adapt to the dark and pupils to dilate. These effects heighten long-term light sensitivity (photophobia), cause eye strain, and create physical safety risks in low-light environments. For example, dark tints can blind workers to drop-offs, forklift pathways, recessed machinery, and other low-light hazards.
Heavy amber and brown tints can alter how the eyes and brain interpret color wavelengths. This can be catastrophic for electricians working with wires, technicians viewing color-coded control panels, or anyone who must decipher color-coded warning signs, indicator lights, or digital displays.
Moving from a brightly lit area into a darker workspace while wearing dark tints forces the eyes to adjust slowly. This temporarily impairs visual and spatial perception, making it difficult for employees to see puddles, obstacles, and changes in floor elevations.
During and after their hazard assessment, employers must confirm that workers follow OSHA eye protection indoor lighting regulations. To help prevent poor visibility, RX-Safety offers these OSHA-friendly lens options.
When you’re considering clear vs. tinted safety glasses, you don’t need to forego tints completely. Very light yellow, pink, or blue tints soften the harsh glare from overhead fluorescent or LED lights without significantly affecting vision.
These specialized lens coatings eliminate glare from any light reflecting off the front and back of the lenses, which dramatically reduces eye strain without impeding VLT.
Featuring a light clear or faintly tinted base, I/O lenses have a subtle mirror coating that reflects bright overhead indoor lights while allowing maximum light transmission.
RX-Safety’s cutting-edge optical lab manufactures high-impact safety glasses that are ANSI Z87.1 certified and equipped with specialized indoor lens treatments.
If you need prescription safety glasses, we build custom prescription lenses directly into your safety frames, providing an alternative to wearing everyday sunglasses indoors.
As long as the tint doesn’t introduce new visual hazards or impair job performance, OSHA regulations don’t prohibit them. Dark outdoor sunglasses are dangerous indoors, but you can still protect your team by opting for specialized anti-glare, light-tint, or photochromic indoor safety lenses.
Keep your team safe, comfortable, and OSHA-compliant. Explore RX-Safety’s comprehensive catalog of ANSI Z87.1-approved safety glasses, and customize your pair with custom anti-reflective, indoor/outdoor, or photochromic lenses today.
