new goggles off whiskey militia. they usually come with a replacement lense so i'd say thats your best bet. sometimes a new pair of goggles with a nice lense is cheaper then a whole new lense
i got the Mace's and i cracked the lens. im not really interested in paying $70 to replace them. haha. esp when i paid $50 from WM. its cheaper to just find new goggles. waiting for some spy soldiers first.
