I received an email reply from Superfocus on December 23rd, saying that they wanted to discuss the details I previously provided. I called them this morning, and spoke to Brad, who was very helpful. He is sending me replacement stems, plus emailing me a UPS label to ship them my frames because the inner lenses are cloudy and scratched, which may be covered under warranty. Because I mentioned the possibility of buying a second pair, he’s offering a 10% discount on a new pair as well. I’m hopeful that they will replace the first pair under warranty because of the problem with the non-removable portion of the lenses. I will have to be much more careful in the future with these glasses if I expect them to last any period of time. What I’ll do is send back the bad ones first and see what they decide to do, before I decide whether to get a second pair.
