I use the same glasses that I shoot Sporting Clays in which are Oakley M-Frame. I have several lenses that I have acquired over the years for different light and background conditions. You can use any sunglasses as long as their rated with impact resistant lenses. A yellow, clear or even an orange lens for low light and maybe a grey or brown lens for full sun. I will say one thing, use as light a tint as you can get away with and still not squint as your eyes focus much better with more light being transmitted to the eye.
