I wanted to save money for my new specs. After my exam and prescription I shopped on Amazon for my frames. After receiving the glasses I took them into the Optometrist of my chose and had them filled. Everyone commented on my new glasses. I am welled please. They are modern, my bifocal looks good in them, and the fit is perfect.

Terrible quality for Burberry

I am really careful with my glasses, I have some Gucci frames for 20 years now. These did not even last me 6 months. The Burberry color turned out to be a sticker which came off in a couple of months. The hinges don't work well and they keep slipping off my nose every few minutes. I had very expensive lenses fitted in to these frames and they should have lasted at least 2 years. Now I am stuck with uncomfortable frames that just drive me crazy.
