This is nearly a perfect lens. I had purchased it along with Flak Jacket frames with the hopes of "warming up" cloudy conditions (I live near Seattle). I was comparing it to a mental image I had of some persimmon lenses I had with M Frames. Although the lenses did not warm up conditions as much as I was expecting, they have turned out to be my favorite lens to date. I've driven in tunnels with them, climbed mountains (with significant tree shade and snow on top) and have been very pleased. They do increase contrast. I feel that with this lenses on is almost the way God intended nature to look. I wear these lenses in the morning, they are great for overcast, and I wear them in dusk. The only condition I've found they are not suited for well is very bright days, but if you're wearing a ballcap with them, even that is doable. These are a great all around lens.

Really love this lens!! High contrast and great in lower light conditions. The world simply looks so much better with this lens. It's slightly less exciting to look at: it will look mostly brown (not pink like in the Oakley photoshop pics) but sometimes there's a slight reflection of blue.
