I got these for work in nerdy costume, thankfully the bigness of them make me look even dorky but they keep sliding off my face when I look down.  They are more approprate size for guys, they fit my boyfriend perfectly.  I'm glad the price of them were affordable and they look just like they are in the picture.  I just wish the discription would explain the size.
So here are the size of the
Glass = 2.1 inches.
Bridge = 1/2 inch
Ear side total (I don't know what its called I don't wear glasses normaly) = 5.75 inches
Ear curve begins = 3 inch

If you have a smaller head like me my ear is about 2.5 inch from face.
