I mentioned it in another thread, but Oakley offers pretty good discounts for vets and first responders if you fit into any of those categories in their OSI (Oakley standard Issue) area
I just placed a significant order from them and saved about 50% ----- my order was clothing, a backpack and a couple pairs of everyday shades, -- but they do have a "ballistic " line that is more LE and Mil specific that i believe meets standards for safety glasses --
- I have always liked the quality of their stuff, but always found their stuff was cost prohibitive without the discount. I've used other sporty brands as i like to mountain bike , like Tifosi and just miscellaneous stuff i can find on sale. Also the optics areas at places like Sams club or Costco a lot of times have good deals on shades, but these are usually more "everyday use" shades like aviators and wayfarer type stuff, but possibly worht a peek if ever in there
