I wore these for the first time the other evening on our new bike as it was evening and I didn't know where my sunglasses were. I knew it would be dusk by the time we left the restaurant and we were on our bike, so I grabbed these and can honestly say, I loved them. They are lightweight, perfectly clear, it looked like i was wearing a pair of glasses. They didn't occlude my vision after dark the way sunglasses do (even though I was the passenger on the back of the bike, I still like to see). I have decided to just leave these on the bike now for those times when I don't need my sunglasses and just need eye ware. They look like trendy glasses, I do need to stick them in a hard case so they don't get smashed by a helmet or something in our hard cases but I have to say, I really like them.
