After just 2 months the arm dropped off the pair of frames. In my opinion the frames are not fit for purpose. Most glasses the arms are screwed on but these had hinges which are glued or soldered onto 2 little metal bits on the frames. The manager would only swap the frame for the identical substandard frame. I tried to contact their Customer services by phone. I basically ended being told they would only replace the same frame as no one else has had an issue with the same frames. Was told the manager at Asda opticians in Roehampton would order me the frames and the branch would let me know when they were ready. She didn't order them instead she chose to send 2 emails to her head office querying the order and even they didn't respond to her. For some strange reason She couldn't be bothered to contact me to query things so after waiting 10 days I rang to find out if my glasses were ready and they hadn't been order. So my advice is AVOID Asda. I certainly regret ever going there
