Thanks you all, its good to know I'm in good company now.
I did find that amber lenses with UV protection really increase the contrast looking THROUGH brush. I have tryed this and it works, you guys try it and let me know if you find the same thing. Look at a tree line/brush line from a field or road that is about 50 yards away while your not wearing the amber lenses. Then put the glasses on, while you are looking. I find that with the glasses on, i notice stuff through and behind the cover very easily, and withouth them, the cover is like a wall, and i cant see thru it as good.
When its really cold, and they fog easily when your walking or climbing, i slide them about a third of an inch down my nose, and the ventilation keeps them clear.
