I just have to say how happy I am. When I ordered the clip on, I didn't realize it was at a default size. When I did, whitin 5 minutes, I panicked. I sent emails and I called. Explaining that I need the largest size. It took a day or two but I got an email back saying they would adjust the order. These clip ons are perfect! They fit almost as if they were made for my glasses. Thank you so very much.
Sincerely,
John
