Amber or copper seems best to me. Note, "green mirror" is not a green lens, it's typically amber, green is just the reflector. Light transmission is important, look it up for contenders. 10-14% is pretty typical for many, but frankly is too dark for evenings, or for small stream fishing under a heavy canopy. So they end up being useful for only mid day, big stream work. Something closer to 20%, or beyond, helps a lot. Even high teens is a large improvement over 10 or 12, though you'll still take them off a few minutes earlier while waiting for a spinner fall.
Glass is huge for scratch resistance and clarity but not impact resistance, so they aren't safety glasses. Straight polycarbonate is the opposite, sucks in clarity and scratches easily, but count as safety glasses. I'd go for glass. Though many high end makers make harder plastics that fall in between on all measures, and vary considerably which way they lean. High end makers often have material choices, too. For Maui Jim, for instance, they make poly, glass, and MauiPure is their tweener that leans toward glass, while maui evolution is a tweener that means toward poly.
I've never understood the logic of going high end and then choosing poly. Yeah, it's cheaper. But still much more than other poly lenses. And will scratch just as quickly. Scratch resistant coatings are limited in what they can handle, the material underneath is what matters.
I love Maui Jim and Costas 580 lenses. They infuse lenses with certain elements that block specific wavelengths, which makes the rest of the colors pop. It works. Colors are brighter. But it is a bit of a parlor trick, and you can decide whether it's worth the extra price. The polarization of those two are great, but so are Smith, Kaenon, Native, and the like. Just stay away from Luxottica stuff (Ray Ban, Oakley, and all the fashion brands), which use inferior polarizing filters.
As always, fit means everything. Don't even think about getting a pair without trying multiple models on, and ensuring you can't see light out the sides or top. Don't worry about lens color while trying on. You can typically order that model with whatever lenses you like.
