The American National Standard Institute’s ANSI Z87 Committee published an
updated standard for safety eyewear, which is now effective.
Make sure your specs meet these specs!
Impact Resistance: There are two classifications for safety eyewear lens impact resistance, basic-impact and high-impact. Consequently, when assessing eye safety risks, it will be
necessary to identify the type of safety eyewear according to the level of risk. Low mass/low velocity risk means that the basic impact lens is adequate. High velocity/low mass or low
mass risks will usually require high-impact lenses.
Marking: All lenses are required to have the manufacturer’s logo embossed on the lens. High-impact lenses must include a “+” following the manufacturer’s logo. Basic-impact lenses will not have the “+” following the logo.
Lens Thickness: Minimum lens thickness for basic-impact prescription lenses will be 3.00 mm, except those having a plus power of 3.00D or greater, which must have a minimum thickness of 2.5 mm. High-impact prescription lenses shall have a minimum thickness of 2.0 mm at their thinnest part. Non-prescription basic-impact lenses have the same requirements as those for prescription basic-impact lenses. Non-prescription high-impact lenses shall not be less than 2.00 mm thick when used in a frame marked “Z87-2”. No minimum thickness is required if the non-prescription protector is mass-produced.
Warning Label: If the protective eyewear meets only the basic-impact rating, it must have a warning label attached. The warning label informs the wearer of the impact limitations of the eyewear. By rule, the warning label should only be removed by the wearer.
