Wiley X continues to be the most widely used goggle on soldiers conducting Operation Enduring and Iraqi Freedom. The SG-1, seen on the cover of Time Magazine, is widely used as the replacement for the Sun-Wind-Dust Goggles (SWDG).

The Wiley-X SG-1 Spectacle System is commercially available protective eyewear for non-prescription lens wearers. The eyewear provides ballistic and UVA/UVB eye protection. The Wiley-X SG-1 is a dual lens eyewear that uses a foam seal around each eye socket to prevent infiltration of wind and dust. The system provides two functions in one: converting from a spectacle to low profile goggle. The lenses provide ballistic fragment protection (clear and sunglass) and have anti-fog and scratch resistant coatings. "Ultra-Foam" seals the eye orbits. The temples disengage with a push of a button and can be replaced with a snap loaded adjustable elastic headband. The frame provides a 90-degree wrap-back. Size: One size fits all.

The Wiley-X frames are on an Approved Products List, requiring units to purchase them using unit funds. But PEO Soldier no longer issues them free to deploying units.

Wiley-X SG-1 Spectacle System provides excellent ballistic protection, but does not provide eye protection from laser hazards. If a mission requires laser eye protection, the soldier must wear the Sun-Wind-Dust Goggles (SWDG), Ballistic-Laser Protective Spectacles (B-LPS), or Special Protective Eyewear Cylindrical System (SPECS) (with laser lenses).
