The US army has settled on Wiley X SG-1 glasses/goggles as a standard for many troops.
They can be used as glasses or goggles(if you detach the arms and attached the included stap attachment).
You can also interchange the lenses in seconds from prescription lenses to non-prescription or from clear to tinted. They are nearly indestructable and look like wrap around sunglasses.
