Review on Enhanced Eye Protection: 3M Virtua Glasses - Polycarbonate Anti-Scratch Technology by Alex Mitra

I use them as cycling glasses. They protect the eyes very well from wind, cold air, dust and bugs. The fact that they don't have a bezel makes for a really good, uninterrupted view. They are very light and I forget I'm wearing them most of the time. They're affordable enough that I don't have to worry about dropping, scratching, or sitting on them. I've never had them fog up while riding, but body heat makes them fog up in cold weather when there's no airflow around them.
