Fortunately, /I don't have any duties, so I don't need duty sunglasses. The sunglasses I pick only need to stand up to the rigors of being carried on a palanquin to and from my chauffeured car to and from the range. Since I'm too lazy to change into shooting glasses at the range, they need to be ballistic rated, and since I'm too lazy to order one of my bearers to pick them up if they fall from my head while I'm in the palanquin, they need to not fall off my head. Also, I want the lenses to be mirrored in an icy, cold, heartless blue to match my eyes.
So far, a pair of Wiley-X AirRage sunglasses has managed to hold this job for the last four years without being lost or broken.
