This is my second time buying Fuse lenses. The first was to replace lenses on an old prescription pair of Ray Bans. This time was to replace scratched up lenses on a pair of Ray Bans that I picked up for $20.00 on that auction site.
Both times my new Fuse lenses arrived very quickly and fit into both frames perfectly, taking less than five minutes to install. You can be comfortable buying Fuse lenses. These are high quality optics with perfect clarity, great scratch resistance, and a better than normal degree of polarization, which I didn't even know was a thing.
Fuse doesn't mention the polarization, I've just experienced it while pouring water into a black plastic cup on a sunny day and not being able to see any light reflection off of the water to tell if it was getting full. While thats a little spooky while pouring water it is amazing when driving or out on the water in a boat and reactions of the sun seem like nothing to your eyes.
One word of advice when picking your lense color, look at the percentage of light that is let through. My first Fise lenses, the gray polarized, let 11% through, and they were a little too dark to drive comfortably in a blizzard but great for very sunny days. The second lenses that I bought allowed 18% light through, the blue chromed lenses, and that, I feel, is perfect for all uses from driving, to going out on the water, to snow days, and leaving them on going in and out of stores.
