Hello. I have a pair of crystal black Monster Dogs, and the black iridum lenses are getting pretty old, these are my beater pair of glasses so i didn't take a whole lot of care into the lenses. I want to replace the lenses, but would try not to pay $65+tax for new MD lenses. I also want to get suggestions for good color lenses that match the crystal black frame. I know that's sort of a hard color frame to find matching lenses for. Maybe titanium iridium? that's pretty neutrual and i do love the titanium iridium. any help is appreciated, thanks!
