i totally agree with all of you...a good pair of glasses make all the difference in the world.
I have action optics and i love them. I have the fishbone model in both amber and gray. I would recommend them to anyone looking for a good pair. They are kind of pricey and not some glasses you will just want to throw on the dashboard of the car. I got mine somewhere in the $160 range per but there glasses range from $70-$170 so theres a pair for most any price range.
I had a pair of nice oakley's (forgot the action's at home) with no retainer to keep them around my neck and was out fishing the big thompson near our house in colorado they fell off into the fast current and were lost for good
I definitely reccommend having neckholders or a strap on them because not only do the glasses cost a bit of change, but most people dont keep two pairs on them at one time...and you dont want to risk a day on the stream losing them
