Love the idea. I an'say anything about the quality of the sunglasses or whether they worth the price tag or not. But try to imagine how things would be if all those bottles were just left around. It could easily take decades or even centuries in some cases. That's not good. We have evolved when it comes to bringing convenience to our lives. But we haven't developed enough technology to counter the harms towards the environment.
Good Citizens sunglasses are actually working to get rid of the waste in productive a. these efforts should be applauded. I hope they won't stop at simply making sunglasses and go on to make all sorts of products with recycled materiel.
