These are probably the most comfortable glasses you could wear for driving. The frame is light and flexible, the lenses cut out glare and are light enough to wear in low light situations (cloudy/dawn/dusk). Due to the flexibility of the frame, you do need to be careful that the arms are not hyperextended or folded under the frames as they may distort - they are easily moved into position again though. This model is so comfortable that I have 3 pairs in different colors and gradients.
Pros: light weight, great lenses, comfortable
Cons: very flexible frame may bend out of shape
