I've been pretty happy using regular 'scrip glasses behind Giro Air Attack lens. Especially with dirt road group riding, where there's a lot of abrasive particulate getting blasted at glasses, and where I might need to quickly wipe a glob of mud or something off, lenses just don't last very long before getting scratched up. Replacement Air Shields are $40, so mich less pricey than scrip lenses.
I was lucky to find the right kind of frames to fit behind both the Giro and the DuxHelm visors back in '12; there's not a lot of room back there, so they need to have wrap-type frames.
