THIS IS MY FIRST BAD EXPERIENCE WITH ANY PRODUCT I HAVE PURCHASED FROM THE AMAZON SITE, BUT IN GOOD FAITH, I CANNOT GIVE A GOOD REVIEW TO THIS PRODUCT. I WOULD EXPECT A MUCH BETTER PAIR OF SUNGLASSES FOR $30. THESE LOOK AND FEEL EXACTLY LIKE CHEAP DOLLAR STORE RACK GLASSES. SAVE THE MONEY AND BUY 30 PAIRS AT THE DOLLAR STORE AND NOT THESE!!!!!!
