Here is one of my two favorite Bling sunglasses.  The purple/blue haze lenses are made to enhance light and contrast in medium to low light conditions.  The lenses are quite dark and have VERY comfortable rubber noseguards that will fit a wide range of bridge sizes and keeps the glasses from slippage.  It protects against harmful UV rays and have a superior coated scratch resistance application to the lenses.  I've applied 125 Swarovski crystals throughout the frame and temple arms to make you look like a goddess!  These crystals are clear, if you want a different color--check the drop down menu.   Please clean lenses with water only, but use a soft damp cloth & a Q-Tip to avoid getting crystal areas wet.
