I am showing my age now, but my Dad loved those lens and he wore that huge frame. I used to wear Revo's in college, but now it is clearly not Nassau and the lens and frame quality is not the same either. As a competitive sailor, I think the the MJ glass lens is the only lens that has not changed but is actually much lighter than the old days and is still made in Japan or Italy by the same manufactures for the last 20 years, ahem to that as China has a long way to go.
