Prescription polarized amber. Similar to the Zurich. I don't know if it is the color or polarization or both but they seem to enhance the sharpness and actually makes the plane easier to see. I even wear them when it is cloudy just because of this.
Me too Missileman, I didn't think I would like the amber when I first got them, but they seem to work better than the gray I used to were..
