Having no bottom/side frame is great for cycling, and I was looking forward to these. Unfortunately, it was immediately apparent when I tried them on that the lenses simply didn't provide enough coverage at the bottom end. In the five minutes I wore them, the glare from the driveway was uncomfortable and the lens edge in my field of view was slightly disorienting. They appear to be well-made, but the lenses are just too short.
I returned them and replaced them with the Oakley Half Jacket XLJ. These are considerably more expensive (of course!) but they are excellent. I haven't skied in them yet, but they're great for biking (road & mtn) and running and I haven't had any fogging issues.
