Not sure if there is a different style of the smith front man but the lenses don't fit. They are serviceable enough for me to use till I get new glasses. On the other hand the color and polarization are exactly like the ones that I had before.Lenses have worked great and are a good price. No complaints.This is the second time I have had problems with fuse lenses. First time they were flawed snow they don’t fit. They are way to small for my swingarm xl’s. I waited to install them for my vacation and now it’s past return time. Don’t know what to doSnapped right into place in my frames and my sunglasses look brand new. I've worn them in the Florida sun for a week and haven't had any problems.Great lenses, nice to have no scratches!AwesomePerfect fit. Good lenses for the price.
