Look. You have to use protective eyewear. In semi- and non-permissive environments, you’ll find that there’s a need to cut the risk to your vision by wearing some sort of protective lens.
At the top of my list of approved protective eyewear is Arena Flakjak Goggles. When I am in the turret scanning for IEDs and bad guys these goggles keep the dust, grit, and flying crap out of my eyes when on the move.
As well, the Arena Flakjak Goggles lens system provides ballistic protection when the rounds start flying and the debris related to combat assails your visual senses.
If you’re kicking around and need a pair of bug eyes, these should be near the top of your list. They most certainly have a nesting place on my head when meeting my objectives.
