Smith Optics vs Costa Del Mar
Costas for sure. I worked at a sporting goods retailer for quite some time, and I took just about everypair of sunglasses outside for a test on colors and clarity. For me the Costas were the best, but everyones' eyes are different. Ask the retailer if you can step outside with them and take a look at natural colors. Revo also makes a very high quality set, but they are not aimed for the fisherman in mind. If you want to save some cash don't hesitate on the glass 400 Costas either. I've got a set and they are wonderful to look through. The 580 is a tad better, but it is not a night and day difference.
