oh yeah, could'nt do it with out them. Contact wearer as well. The only thing I worry about sometimes is that I wear GASCANS S and drivers cant see me make eye contact with them. Hopefully by my head liking right at them they get it, but you never know. Performance has some good interchangables on sale right now as I should be wearing some clear ones at night. I think I am gonna jump on these, if anyone has them......
