WileyX goggles may be virtually bombproof, but the lenses do get scratched with normal industrial use. I work on an oil rig and my work area ranges from outdoors to enclosed spaces below decks. Lens fogging became an issue for me while working, so I modified my original lenses by cutting out some of the foam padding in contact with my face to increase the air flow over the lens. Last month, I needed to get some spare lenses for my WileyX SG-1 goggles. I found the SG-1 V-Cut Clear replacement lenses (WX-SA-LENS-70C) on OpticsPlanet.com. These were exactly what I needed. The V-Cut design has larger ventilation slots and this has gone a long way in reducing fogging of my goggle lenses while I work. The goggle insides maintain their good looks, with no "customization" required. An excellent prduct!
Pros: V-Cut lenses allow for better ventilation - less fogging
Cons: None
