I have a pair of prescription Costa’s that I like a lot, I’ve had them for a few years but there are other quality options out there now for less. I’ve tried my friends Sunclouds and was pretty impressed. As far as lens color, copper or bronze type works for me on streams. I have gray/blue lenses I use on the Bay and ocean. The copper/bronze creates good contrast in freshwater and gives me a little more light when the sun sets.
If you are active/former military, law enforcement or fire, GovX.com offers good discounts on high end sunglasses.
