I've had my RB4181s for years now, been ordering replacement polarized lenses through Luxottica for years as well (when they were $40 shipped), but now that they charge $75 for a pair I'm happy to have stumbled on these. These G15 polarized lenses are almost identical to the ones that come with the sunglasses. The only difference I've spotted is that RayBan lenses are just a tad more green/blue in color, maybe slightly more clarity as well but not enough to warrant spending $40 more. Check out my photos, the right side are Raybans lenses, left side are the Lenzflip.Thanks for an excellent product!EDIT: ebay isn't allowing me to post photos for some reason.
