I am leaving one star because I've only had these glasses for two months and they already show a crack in the glass in two separate places. One right by the nose piece and the other one (totally independent) at the mount of the ear bracket. Both cracks run through the little tiny hole that mounts the hardware pieces to the glass indicating that the little hole creates a material weakness which I'd consider a clear design flaw. I've had other Maui Jim sunglasses in the past with similar problems. I love the light weight design and super clear vision but these sets don't last long enough for the cost.
