Oakley juliets are the best sunglasses that I have ever had and I intend on buying more pairs as well as at least one pair of pennys.  They are very durable and dont fall off of your face.  I havea pair juliets with a plasma frame and replacement fire lens, ice polarized lens and a ducati black iridium lens and I bought all of them off eBay, I give these glasses a 5 out of 5 rating for style, functionality and durability, I highly recomend them for anyone who wants stylish glasses with the ability to replace the lens and great functionality for an active lifestyle, hope this helps.
