I bought a pair of Orvis polerized glasses with copper lenses a few years ago. They were very good until last October when I got all excited and stepped on them while landing a 17 pound coho. I called Orvis regarding repair and after a month's wait, they replaced them with a new pair! (These are $150 glasses). The copper lenses were discontinued, so I requested vermillion, which are good low-light lenses. I fish mainly for steelhead and mainly in mornings or dark days when I can. Amber or vermillion are better in these conditions than gray. I have a gray pair I use for lakes in sunny summer. During the month I was without my copper/vermillion lenses (December 01), I not only caught few fish, I fell in a number of times because I couldn't see boulders under the river surface.
