Ballistic Rated

High Mass Testing
Frame and lenses must be able to withstand a 500g (17.6 oz) pointed steel projectile dropped from a height of 127cm (50 inches).

  • Lens cannot fracture.
  • Rear surface of the lens cannot be penetrated.
  • Lens must remain retained in the frame's chassis.
  • Frame and lens cannot touch the eye area during impact.
  • No parts or coatings can completely detach from the interior of the lens or frame chassis.

To pass the test no frame parts or lens fragments may be ejected during impact.

High Velocity Testing
A 6.35 mm (0.25 inch) diameter steel ball is shot at the lens at a velocity of 45.7 m/s (150 ft/s). In order to pass, the lens cannot crack, touch the eye area, or allow the projectile to pass through the rear surface. It must also remain retained in the frame's chassis.

6.35 mm (0.25 in.) diameter steel ball weighing 1.04 g (0.037 oz): 45.7 m/s (150 ft/s)

MIL-PRF-32432(GL)BALLISTIC FRAGMENTATION TESTING
A 0.15 caliber, 5.85 (+/- 0.15) grain, T37 shaped projectile is propelled at the lens at 195m/s to 201m/s (640ft/s to 660ft/s). To pass this test, a sunglass must meet all of the following conditions:

  • The lens must not crack or shatter.
  • The lens must remain retained within the frame chassis.
  • The sunglass must not fall off the head form during or after impact.
  • The projectile must not penetrate the rear surface of the lens.
  • No parts or coatings may detach from the interior of the lens or frame chassis.


0.15 caliber, 5.85 (+/- 0.15) grain projectile: 195m/s to 201m/s (640ft/s to 660ft/s)
