In today’s world, protective eyewear goes far beyond fashion—it’s about safeguarding one of your most delicate and essential senses: your eyesight. Whether on a construction site, in a laboratory, or enjoying outdoor sports, understanding ANSI eyewear standards can mean the difference between optimal protection and preventable injuries. This guide dives into the key types of ANSI standards and explains how they ensure safety, comfort, and performance.

What is ANSI?

The American National Standards Institute (ANSI) is a private, non-profit organization that sets voluntary consensus standards for products and safety in the United States. For eyewear, ANSI standards regulate design, durability, impact resistance, and the optical quality of lenses and frames. These standards are particularly crucial for industries where eye injuries are common, as well as for prescription and non-prescription eyewear.

Key ANSI Standards for Eyewear

1. ANSI Z87.1 – Occupational Safety Eyewear

The most widely recognized safety standard in the U.S., ANSI Z87.1, applies to safety glasses, goggles, face shields, and other protective devices used in workplaces with eye hazards.
Important Features:
  • Impact Resistance: Tested with high-velocity steel balls or heavy objects to ensure lenses and frames can withstand impact.
  • Splash and Dust Protection: Optional markings like D3 (liquid), D4 (dust), and D5 (fine dust) indicate protection against specific hazards.
  • Radiation Protection: UV (U) and infrared/visible light (R, L) filters may be included for specialized workplaces.
  • Markings: Z87 for basic protection, Z87+ for high-impact certification, Z87-2 for prescription eyewear, with additional symbols indicating specific protections (W for welding, H for small head sizes, V for variable tint, S for special purposes).
This standard is mandatory for workplaces under OSHA regulations and ensures workers are protected from the most common occupational hazards.

2. ANSI Z80.3 – Sunglasses and Non-Prescription Eyewear

ANSI Z80.3 focuses on consumer eyewear such as sunglasses, fashion glasses, and sports eyewear. It emphasizes optical clarity, UV protection, lens durability, and frame integrity rather than high-impact resistance.
Key Considerations:
  • UV Protection: Lenses must block harmful UVA and UVB radiation.
  • Luminous Transmittance: Ensures adequate visibility without distortion of traffic signals or natural light.
  • Frame Strength: Durable enough for outdoor activities and regular wear.
  • Applications: Ideal for sunglasses, casual wear, prescription-free lenses, and sports eyewear with optical correction.

3. ANSI Z80.1 and Z80.31 – Prescription Lenses

  • Z80.1: Governs ophthalmic lenses including prescription glasses and ensures that lenses are manufactured to meet precise optical quality and safety measures.
  • Z80.31: Applies specifically to over-the-counter reading glasses or non-prescription lenses, focusing on optical performance, safety, and durability.
ANSI markings provide immediate clues about eyewear functionality:
Marking

Z87+
High-velocity impact protection
Z87-2
Prescription eyewear
D3
Splash protection
D4
Dust protection
D5
Fine dust protection
U6
Maximum UV protection
R3

W shading (e.g., W3, W5, W10)
Welding lens shade levels
V
Adjustable/variable lenses
S
Special purpose lenses (e.g., color recognition)

These codes help workers and consumers quickly identify eyewear that meets the hazards they face, from industrial projects to outdoor recreation.

Types of Safety Glasses Aligned with ANSI Standards

  1. Prescription Safety Glasses: Combine vision correction with protective features. Customization options include wrap-around frames, anti-fog coatings, and polycarbonate lenses.
  2. Non-Prescription Safety Glasses: Versatile protective eyewear with clear, tinted, or polarized lenses. Ideal for high-impact environments without corrective needs.
  3. Polarized Safety Glasses: Reduce glare and improve contrast, particularly useful for outdoor work or bright environments. Often used in construction, driving, or water-based jobs.
  4. Anti-Fog Safety Glasses: Feature advanced coatings to prevent condensation, essential for fluctuating temperature or high-humidity workplaces.
  5. Blue Light Blocking Safety Glasses: Protect against digital screen strain while maintaining ANSI-compliant safety features.

Selecting the Right ANSI-Certified Eyewear

When choosing protective or prescription eyewear:
  • Assess Hazards: Identify the primary risks—impact, radiation, liquid splashes, dust, or UV exposure.
  • Check Markings: Confirm ANSI compliance and relevance to your hazards.
  • Consider Fit and Comfort: Proper fit ensures consistent protection. Adjustable features improve wearability over long periods.
  • Verify Authenticity: Buy from authorized manufacturers or retailers, check product labels, and consult official ANSI databases.
  • Balance Functionality and Style: Especially for sports or fashion eyewear, functionality should not be compromised by aesthetics.

Conclusion

ANSI standards set the benchmark for eye protection, ensuring that eyewear meets rigorous safety, durability, and optical quality requirements. From industrial Z87-rated safety glasses to casual Z80.3 sunglasses, recognizing these standards empowers you to make informed choices, improve workplace safety, and protect critical vision. Whether you’re navigating a hazardous worksite or enjoying the great outdoors, choosing ANSI-compliant eyewear is an investment in lasting eye health and peace of mind.
By understanding ANSI standards and their practical applications, you can confidently select eyewear that balances safety, comfort, and functionality, providing a clear view while keeping your eyes shielded against daily hazards.

Protect Your Style. Protect Your Grind.

When it comes to safety eyewear, the ANSI rating isn’t just a technical detail—it’s your frontline defense. Whether you're on a job site, in a workshop, or out in the elements, knowing which ANSI rating fits your grind is key to staying protected and compliant.

🛡️ What Is ANSI Z87?

ANSI stands for the American National Standards Institute. The Z87 standard sets the benchmark for impact resistance, coverage, and durability in protective eyewear. If your glasses don’t meet ANSI Z87 standards, they’re not built for real-world hazards.

🔍 ANSI Z87 vs. Z87+

  • Z87: Basic impact protection. Good for low-risk environments.
  • Z87+: High-velocity impact protection. Required for industrial, construction, and high-risk settings.

At Califas 22, we don’t mess with the minimum. Our Z87+ rated lenses are built to take hits and keep you moving—without compromising your look.

⚙️ When to Choose Z87+

  • Construction sites
  • Metalworking or carpentry
  • Landscaping or outdoor labor
  • Any job with flying debris or high-speed tools

If you’re working with power tools, machinery, or anything that throws sparks or fragments, Z87+ is non-negotiable.
