The ANSI Z87.1-2015 high-impact velocity test consists of a 1/4″ steel ball shot at 150 fps, which is around 102 mph. Chances are most polycarbonate lenses may survive a 500 fps impact, but they haven’t been officially tested. In my opinion, it’s not worth the risk!
You should seriously consider wearing ballistic rated eyewear because they’re tested using the US Military standards for impact protection (MIL-PRF-32432). In brief, the U.S. military standard requires that ballistic eyewear must be able to withstand up to a .15 caliber at 640 fps for spectacles and .22 caliber at 550-560 fps for goggles.
Thanks Jerome, this is exactly the point I have been saying this whole time. But it seems like everyone around here is so stuck in their ways of attempting to prove me wrong, that they prove themselves wrong in the process.jeromeL wrote: ↑Thu Apr 20, 2017 2:34 pmTo be fair to LFAK ANSI Z81.1 doesn't actually test using a bullet. Only the military standard test that way.

Now I am a reasonable guy here, I'm just trying to have a decent conversation with everyone. And all anyone has ever done in this thread is try to make me look ignorant, but as everyone here can see, the only thing that looks ignorant around here are the people trying to pick a fight with me. I'm very sorry you guys look like a bunch of big idiots right now, but it's not my problem. If you guys would forget about the hate you have for me this forum would be a better place and you would look a lot better, instead of trying to bash me all the time like a sorry piece of trash. Everything I have said so far has been spot on, 100% fact. Why would you want to pick at that?
Like I said before I am willing to forget all of this mess and pretend like it never happened. This is so stupid, and so idiotic, that I want nothing to do with it.
Have a good day
Water reflects only 10% of UV rays so that may actually be enough. Even if plummet thinks it looks kookyWindstoked wrote: ↑Thu Apr 20, 2017 5:21 pmThe best solution to sun-related eye pain/visual impairment I've found is a visor/cap, preferably a wide-billed one. It made an incredible difference.
I was having significant eye issues at my local beach when morning kiting due to a dominant west wind pattern and resultant facing the sun in the east. Sunglasses were a hassle, but the problems went away with a cap. For real early sessions I add polarized sunglasses to block the glare off the water.
I tie the cap to my wetsuit zipper-pull string, or use my helmet to hold it on.

Did you read anything in this whole thread? We're talking about spy sunglasses being bulletproof, not "Millitary graded eyewear"
