Great shades!  I own two pairs, and love them both; keep 1 pair in the car and 1 in the house.  Fit wonderfully, no discomfort from too tight nose pieces.  EASY EASY lens changing.  My only complaint is that I only have one pair with the cool clarion lenses!!  I have had one pair for at least 3 years, and the other for 2 full years with near daily wear.
