I agree with katophan, as a full scale pilot I wear Serengetis. The optics are second to none and the driving lenses block blue light which in turn enhances all other light, once you try a pair you will never wear anything else. Just go into your local glasses store and try on a pair look through them then over them a couple of times, the result is quite amazing. Plus they now have more frame styles than just the aviators.
Only setback is they are true glass, when you drop them onto the ramp from the steps of a BE1900 they tent to crack. (totally my fault not the glasses)!!
