ESS for life
Depends on what you're staking in these glasses. ESS makes awesome ballistic glasses that are no crap. We get issued their ICE glasses, and I decided to see how well they actually held up. I had an old lens that's pretty scratched up from last trip to the sand box, so I did my own little product test. I started with #8 low-brass lead shot at about 5 meters from a mossburg 12 gauge. Nothing penetrated. I worked my way up to #4 high-brass steel shot before anything penetrated the lens. If you want something that will honestly protect your eyes from anything (including IED's at a distance), get a pair. They're cheaper than oakley's, too. You can find the ICE's for $50.
