I have the havana/brown lens and they work great! I like the higher contrast the brown lens gives me, makes cloudy days brighter and yet I don't have to strain my eyes on the sunny ones. I just wish they had nose pads to prevent sliding when I start to sweat. I tried on a ton of Native glasses because they had the temple and nose pads, but they just didn't fit on my face well. I have a medium sized head, hat size is around 7.5-7.75.
