These lenses fit my two year old Fuel Cell sunglasses 'ok.' A couple of things. The overall diameter of these lenses is SLIGHTLY larger, which made popping them in slightly difficult. They're not big enough that it causes any distortion, so that's good. I will say that they were also slightly thinner than the Oakley lenses, which is fine. They work fine, they're clear, but they don't have that super sharp quality that a new pair of Oakley lenses would have. That said, for what they cost, they're a bargain.
