These are the lightest, most comfortable, sharpest cycling glasses I have ever owned. I love the fact that I can use them in all daytime conditions. They are great is bright sun and equally good on foggy or cloudy days. They are so comfortable I sometimes forget I have them on. Perhaps best of all is that there are no frames obstructing vision. Every other pair I owned had some limiting factor which created blind spots, something that can be a major problem when you ride the roads, as I do. My last glasses had frames which got in the way when I turned to check for cars coming up on my left side. These allow unobstructed periferal vision at times like that, a major safety factor. I cannot recommend this highly enough.
