Glasses impact rating

[47chevycoe]

Hey guys, I was looking to buy some replacement clear lenses for my Oakley frames. There are some aftermarket options that are about 1/2 the price. Their impact rating is 80.3 and I think the oakley lenses are 87. Can someone school me on impact ratings? Primary use will be pistol shooting and also work on the lathe and milling machine.

ANSI Z80.3 - establish standards for noncorrective lenses that are intended for attenuation of light and for fashion eyewear, and for the flammability and durability of frames and lenses.

In other words, NOT impact rated.

ANSI Z87 certification standards are for blunt impact, radiation, splashes and droplets, dust, and/or mall dust particles.

For impact rating, they need to be Z87+

87.1 is a basic, low impact spec, the "+" gives it a high impact rating. Isn't that what you're buying them for? I've worked around machinery all my life, I always go for the highest rating available.

As long as you don't need prescription glasses (like I do), even the "+" spec is cheap. But there is a difference, just look at that McMaster page
