I have been a customer of 39 $glasses.com for over eight years. Wow the prices of the glasses do go up quickly when increasing the quality of your lenses, these are still half the price of prescription glasses from stores. I have always been happy to return to the site and get well-made products quickly. Granted, I'm pretty easy to please when it comes to cheap glasses, whether they be metal frames or plastic frames. But I've also loved their transition lenses and sunglass options!
