Is there a way to swap the lenses in a new zero. I cant even figure out how they are held in place. I've seen quite a few pairs on ebay that are called "custom" but just look like the lenses have been switched around fro other pairs.
I haven't tried it, but I imagine it's some sort of hook system that's just snug enough to hold. I haven't had the courage to try it for myself though.
I'm in the same boat. I've got two pairs that are in fair condition that I could make one good one out of but I'm not sure if I'm willing to risk it yet.
