Someday, when I grow up, I want some Costas with the 580 lenses
They are the sweetest of all the ones I have tried (I've owned the 420s, not the 580s)
Costa has (least they had last time I looked) a color lense guide that suggest colors based on type of fishing/activity. So for the 420 series, offshore were blue I think, driving is gray, inshore brown I think, sunrise & sunset were vermilion.
Nice glasses, I almost keep getting them but then I'd need to hide the receipt plus I would need to insure them
