What Does ANSI Z87.1 Certified mean in Safety Glasses?
January 26, 2025

When it comes to protecting your eyes in hazardous environments, the importance of wearing the right safety glasses cannot be overstated. Whether you’re working in a laboratory, on a construction site, or in a manufacturing plant, ANSI Z87.1 Safety Glasses are designed to shield your eyes from potential dangers.
But what does ANSI Z87.1 certification mean, and why is it so critical when selecting safety eyewear?
In this article, we’ll break down the essentials of ANSI Z87.1 certification, its requirements, and how to ensure you’re getting the best protection for your eyes.
The ANSI Z87.1 certification is a safety standard established by the American National Standards Institute (ANSI). It outlines the criteria that safety glasses and other protective eyewear must meet to effectively guard against workplace hazards. These hazards can include impact, radiation, liquid splashes, and even dust or fine particles.
The standard is widely recognized across various industries and serves as a benchmark for high-quality eye protection. Employers often require workers to wear safety glasses that meet ANSI Z87.1 standards to comply with workplace safety regulations and reduce the risk of eye injuries.
To understand what ANSI Z87.1 certification means, it’s essential to delve into the specific elements covered under the standard. The certification ensures safety glasses meet the following criteria:
One of the most critical aspects of ANSI Z87.1 certification is the ability of safety glasses to withstand high-impact forces. Certified glasses undergo rigorous testing, including high-mass and high-velocity impact tests, to ensure they can protect against flying debris and other hazards.
Safety glasses that meet the ANSI Z87.1 standard are marked with specific codes on the lens or frame to indicate their compliance and level of protection. For example:

Understanding ANSI Z87.1 Certification
The ANSI Z87.1 certification is a safety standard established by the American National Standards Institute (ANSI). It outlines the criteria that safety glasses and other protective eyewear must meet to effectively guard against workplace hazards. These hazards can include impact, radiation, liquid splashes, and even dust or fine particles.

Key Elements of ANSI Z87.1 Certification
To understand what ANSI Z87.1 certification means, it’s essential to delve into the specific elements covered under the standard. The certification ensures safety glasses meet the following criteria:
Impact Resistance
One of the most critical aspects of ANSI Z87.1 certification is the ability of safety glasses to withstand high-impact forces. Certified glasses undergo rigorous testing, including high-mass and high-velocity impact tests, to ensure they can protect against flying debris and other hazards.
Lens Markings
Safety glasses that meet the ANSI Z87.1 standard are marked with specific codes on the lens or frame to indicate their compliance and level of protection. For example:
- Z87: Indicates basic impact protection
- Z87+: Signifies high-impact protection
- Additional markings may denote resistance to radiation, splashes, or dust
- UV Radiation: Many safety glasses provide ultraviolet (UV) protection to safeguard against long-term exposure to harmful rays.
- Liquid Splashes and Droplets: Essential in environments involving chemicals or biological materials
- Dust and Fine Particles: Important in construction, woodworking, or other dusty settings
- Environment: Assess the specific hazards in your workplace, such as impact risks, radiation, or exposure to chemicals.
- Fit and Comfort: Proper fit is essential for effective protection. Glasses that are too loose or tight may not provide adequate coverage or could become uncomfortable during long shifts.
- Prescription Needs: If you require vision correction, opt for prescription safety glasses that meet the ANSI Z87.1 standard.
- Durability: Choose glasses made from robust materials that can withstand daily wear and tear without compromising protection.
Protection Against Non-Impact Hazards
Beyond impact resistance, ANSI Z87.1 Safety Glasses must also protect against:
Optical Clarity
Certified safety glasses must meet stringent standards for optical clarity to ensure they don’t distort vision or cause eye strain. This is particularly important for those who need prescription lenses integrated into their safety glasses.
Why ANSI Z87.1 Certification Matters?
Workplace hazards can vary significantly depending on the industry, but eye injuries are a universal concern. The ANSI Z87.1 certification is your assurance that the safety glasses you choose provide reliable protection against specific risks.
Compliance with Workplace Regulations
Many workplaces adhere to safety regulations that require employees to wear ANSI Z87.1-certified eyewear. Without the proper certification, both employers and employees could face fines or increased liability in the event of an accident.
Peace of Mind
Knowing that your safety glasses meet the ANSI Z87.1 standard ensures you’re investing in high-quality protection. For workers who face daily exposure to potential eye hazards, this peace of mind is invaluable.
Versatility Across Industries
From healthcare and manufacturing to construction and laboratories, the versatility of ANSI Z87.1 Safety Glasses makes them a trusted choice in diverse settings. The certification ensures that the glasses are suitable for various tasks and environmental conditions.
How to Identify ANSI Z87.1 Certified Safety Glasses?
To ensure your eyewear meets the ANSI Z87.1 standard, look for specific markings on the frame or lenses. These markings indicate compliance and help you understand the level of protection provided. Additionally, purchasing from a trusted supplier like RX Safety Canada ensures that the glasses you receive are genuine and meet the necessary safety standards.
