ANSI Z87.1 Standards for Safety Glasses


The ANSI Z87.1 standards are used to test and certify the impact resistance of z87 safety glasses and face shields. These standards are used by manufacturers and organizations involved in the construction industry, sports, manufacturing, medical professionals, and more.


The ANSI Z87.1 standard for safety glasses is a comprehensive guide for manufacturers, distributors, and users of eye protection equipment. These standards provide a framework for developing and testing protective eyewear products to ensure they are safe to use in a variety of environments. The ANSI Z87.1-2015 document contains two parts:

Z87.1-2015 Standard for Industrial Eye and Face Protection

This standard was published in 2015, and it is important to note that this version supersedes all previous versions of the standard. The purpose of ansi z87 safety glasses is to provide guidelines for the selection and use of safety glasses, goggles, face shields, and other types of eye protection devices. In order for an eye protection device to be considered compliant with ANSI Z87.1-2015, it must meet certain requirements outlined in this document.


The current standard is ANSI Z87.1-2015, which was adopted by the American National Standards Institute (ANSI) in 2015. It’s a voluntary consensus standard that’s designed to protect against injuries such as cuts and abrasions, impact injuries, chemical splashes, and explosions. The purpose of this guide is to help you understand what’s required by the new regulations so you can meet them–and keep employees safe while they’re on the job!

Eye and Face Protection, General Requirements

Eye and face protection is required for all types of work. The requirements are different depending on the type of work. They are based on the hazards of the work environment, as well as your risk of injury. The new regulations require eye and face protection for:

  • The protection of eyes and face from flying particles, molten metal splash, and sparks
  • Protection against chemical splashes or vapors in areas where they may be present
  • Protection against flying objects such as fragments from hand tools, equipment, or material handling devices

The following table lists some examples:

Impact Resistance

Impact resistance is the amount of energy a lens can absorb before breaking. This is measured in foot pounds (ft/lbs), which is the amount of force required to accelerate one pound of mass at 1 ft/s2.

The most common way to test a lens’ impact resistance is by dropping a weight on it from 80 inches high. The size and type of weight used depend on how much impact protection you need:

  • Smaller weights are used for lighter lenses like safety glasses or reading glasses. Larger weights are best suited for heavier lenses like sports goggles or welding helmets since they’re more likely to break if there’s no protection against impact forces.*

Nonimpact Resistance

Nonimpact resistance is the ability of the lens to withstand everyday wear and tear. Everyday wear and tear can include scratches, abrasions, or abrasions from contact with other surfaces.

To test nonimpact resistance, place a piece of sandpaper on a flat surface and rub it back and forth against your lens for 30 seconds. Then look at your lens through a magnifying glass; if there are any scratches or marks visible on top of your lens they will show up under magnification as small dots or lines that run parallel to each other across the entire surface area of your eyeglass lenses. If you see any such markings then this indicates that your safety glasses do not meet ANSI Z87+ standards for Nonimpact Resistance (NIR).

Face Shield Testing

To test the face shield, it must be placed in front of a head form that is mounted on a test fixture. The impactor is then dropped from a height of 1 meter onto the center of the face shield at 0 degrees (horizontal). This simulates a head hitting the face shield directly in front of it.

The nonimpact test uses an airbag to push against one side of your face while you’re wearing your safety glasses and standing still with good posture. This simulates someone falling into you while they’re wearing their own pair of safety glasses, which could cause them to strike yours as well if they hit at an angle that pushes them toward yours instead of away from theirs.


We hope that you’ve found this guide helpful and informative. If you have any questions or concerns, please contact us! We’re here to help ensure that your safety glasses are the best they can be. Safety glasses are an important part of your uniform. They’re one of the first things that people notice about you, and they can make or break a first impression. You have to be sure that your safety glasses are not only comfortable but also stylish—after all, you want them to look great on anyone who wears them!
