I bought a pair of Smith`s polarized glasses (with real glass) and they are a bit pricey,,junk too.
Mine after about 16, 18 months clouded up for reason`s beyond me.
I called them and talked to them about it and they are warranted for a year
so it was basically tough luck.. (I won`t get into the pleading part.*L*)
One of the girls on my soccer team jumped and gave me a hug after scoring a goal
and snapped both, yes, both of the earpieces off. They were around my neck on a
croakie at the time. which I figure now was a good ending to them as by then they
had definite smokey hue to them.
I bought a cheaper pair of Bolle`s polarized and they seem to work to just as good
as the Smith`s for a about 1/3 the cost.
Just my .02
