After 100K plus miles, my lenses are pretty pitted. Can glass be polished? That's actually a slight benefit to the poly lens as I see it. They can be polished to remove "small" pits caused by road debris. Myself, I also like the smooth clean look of them. Not yet sure I'm going to pick-up a set. The fact that they're not D.O.T. approved, and can get me a ticket because of it, has me hesitant.
