I plan to try to contact the seller. I have bought several pair of these AO glasses in the past few years. I really like them...but...this pair was way below standards. The lens did not fit the frames well. The back of the lens was sticking past the frames. They appeared very light ( less weight) compared to previous AO glasses I bought. I weighed them on a lab scale and they were 30% lighter (less weight) than my old pair that is two years old. I am not satisfied with the quality. I sure hope all of the AO eyewear has not been cheapened un like this pair.
