The following 7eye frames are ANSI Z87.1 compliant:
We can supply these glasses with a choice of 7eye clear, copper, grey, polarised grey, polarised copper, light-reactive grey to clear, or light-reactive brown lenses - see our page on lens colours.
ANSI stands for the American National Safety Institute and Z87. 1 is the name of the standard pertaining to safety eyewear.
For eyewear to be ANSI Z87.1 compliant, it must pass a series of stringent tests ranging from the optical quality of the lenses to the impact resistance of the frame.
The 7eye glasses listed above have been tested by an accredited third party company and pass all pertinent tests.
What does impact resistance mean?
For eyewear to be classed as having "impact resistance" it means that it has passed the high mass impact resistance test.
This test consists of a 500 gramme pointed metal projectile being dropped on the lenses from about 4 feet above. The eyewear must remain intact with no frame or lens pieces detaching. Upon impact in an accident for example, inferior lenses will shatter into many pieces which increases likelihood to pierce the eyes.
All lenses by 7eye are impact resistant which means that they will not fracture into many pieces, thereby decreasing the likelihood of damaging the eyes.
