Thanks BTB for a Great Pair of Sunglasses October 7, 2011
Reviewer: jdnavy from Park City, UT  
While I was a little unsure of ordering online without trying them on first, I was very happy with these glasses – clear and lightweight and fit my face perfectly after adjusting the nose pieces to my comfort level (cool feature by the way).  I compared these lenses with a much more expensive hi-end pair and was amazed to find the clarity of these glasses were much better.  I played golf last weekend and this was the first time in my life I’ve kept my sunglasses on the entire 18 holes – for every shot and putt – never before have I done that with a pair of sunglasses – they hugged my face and never moved.  Thanks again for a quality pair of glasses at an excellent price!
