My only complaint is that they do fog up if I get stopped at a light, but I'm afraid that is pretty much unavoidable.
Now this is a nice feature - this might be worth getting another pair of single vision cycling sunglasses. I know that Tifosi can handle my astigmatism prescription (I've already checked), and this would be nice - but it would still be single-vision.

How sensitive are the lenses? Would they adjust to the light differences found in the woods over the sunny open roads? I hope that question made sense...

If I could find all of this in a progressive wrap-around frame with shatter-proof lenses that cost less than one of my bikes...
