Got these replacement lenses 2 years ago. They work great and fit perfect. I was a little skeptical as these were plastic replacements and not the original glass type. I replaced them anyway as I had a bunch of scratches on the originals. Glad I did! The lenses being plastic are actually lighter and make wearing these sun glasses much more enjoyable as there is less weight. I am placing another order soon as I have a tendency of dropping my sunglasses off my head a lot and scratching the lenses. The lenses hold up really well to normal everyday use and cleaning with lens cloth wipes. No scratches from that kind of use, only ones I have are from me dropping them.
Thanks Dave - Please note though that you should only use warm, soapy water and a micro-fibre cloth to clean the lenses. Cloth wipes can cause the polarisation layer to bubble and lift. From the Sunglass Fix Team
