There are four or five BIG threads on this site that disscuss this. A search will yield quite a bit of insight.
I have found Maui Jim glasses to have terrific quality lenses and frames, but they are too dark for sight fishing and lower light conditions.
Action Optics seems to have the best lens colors, best selction and decent fames. Costa Del Mar also has some good fishing glasses. Keanon is up and coming.
I prefer amber and copper for all around site fishing (and fishing in general). I prefer yellow for over cast and low light. I like grey for styling around and I like dark lenses for scoping the ladies and welding.
I like glass lenses because they last longer and have better optics. I like poly lenses because they are lighter an more comfortable (just scratch too easily).
One cast can change your day...maybe your life.
