If you have two rivets in the nose bridge,they are genuine most likely and if you see rivets at the bottom of the frames,fakes don't have that,i'm sure the juliets are the x metal frames...
Yup, rivets on the nose bridge, torx screws on the bottom of the frames and arms.
Although I know the lenses are fake, cos I put them in a few months ago! I took the originals out as they were non polarized, and the fakes I bought from the USA (about £40) were polarized. Perfect fit though.
