I've been wanting a pair of Oakleys for a long time and when I saw these and the price they were listed at, I decided to finally take the plunge. I'd love to say these are easily 5 star sunglasses, but a couple things keep that from being true. At least for me. First, the fit. I checked the measurements before ordering and they should have fit well. They don't. I can still wear them, but if you have a small head like me, they will feel a little loose. They won't fall off or anything as they aren't that large, but they aren't as secure as I was expecting. Second, the light blocking capabilities. I have a pair of Tifosi's that are polarized and have dark lenses. Those do a great job of blocking out bright sunlight while still making it easy to see. Being light sensitive, that is important to me. These don't really do that. Don't get me wrong, they filter pretty well, but they are listed as being good for bright light. Unfortunately, I still found myself being sun blinded. Again, I am light sensitive so your experience may be different. Ok. If we are going to mention the negatives, we have to include the positives. Let's start with the Prizm technology. Ah! This is really cool. Even though the sunglasses provide a bronze outlook, certain colors just kind of pop. Blues, greens and reds really stand out more. I won't go as far as saying they are vibrant, but it's definitely noticeable and I'm a fan. The frames. They are very lightweight yet durable and the glasses are comfortable to wear despite being a tiny bit too large. They don't dig into my nose or around the ears. I can't really feel them when I have them on. That's how light they are. They seem sturdy and as long as you take care of them, these should last. The colored lenses. These are really beautiful and give off a nice mirrored look, even though they aren't. It makes them very fashionable and they can be worn with anything. For your protection, they are 100% UV coated, filtering UVA, UVB and UVC as well as harmful blue light up to 400mm. They are also polarized, which you can tell while wearing them. So, there you go. Even though they are a little big and don't provide what I personally need for bright sunny days, I have no plans on returning them. They have proven to work well when it's overcast, or at least not so bright out, and they look great. Not to mention they were a fantastic deal considering the name brand.
