The difference between MIL spec and ANSI Z87
Ballistic standards for eyewear go beyond the industrial safety eyewear standards. They are meant to protect our military against projectiles that travel at higher speeds than industry debris. Ballistic impact tests are more than 4x the velocity of ANSI high impact tests. In order to meet the MIL-PRF-31013 standard, eyewear must pass Vo test using a 0.15 caliber, 5.8 grain, T37 shaped projectile at a velocity of 640-660 feet per second. Check out our eyewear that meets these rigorous tests. MIL-PRF-31013 safety eyewear.
