Si vis pacem, Para Bellum.
"If you want peace, Prepare for war"
I use my everyday sunglasses... oakley gascans with HD polarized lenses u can pick up a pair at hibbit sports for about $185
I used the general 5 dollar safetyglasses from walleyworld, i've had them take all sorts of sh!t and not bust, but next time out I'm going to try my riding glasses with clear lenses.
------------Space Not for Hire.-----------
I use the amber ones which allows me to see the target brighter in gloomy weather. I may have to check the stores to sample the Oakleys this week.
I'm not trying to sell for rudy and if any other brand has the light changing or "auto darken" red lenses. I would give them a try.
