I wear Oakleys and they are really great. I don't think mine are women specific since Dh ordered mine for me when I first got into cycling and they're the same kind he has. It was sweet of him to get me sunglasses, but it would have been nice to choose my own frame.

But, having said that, I absolutely love the yellow lenses, which I wear when it's both dark and light out. The lenses block glare really well and are crystal clear to look through. More clear than without them sometimes! The lens wraps a little around the sides of my face, which helps keep the wind out of my eyes. My friend, who wears contacts, discovered she needed something that blocked more wind when her contacts kept drying out.

I have a reasonably small head, but probably not as small as yours. I wear a medium Giro. Yet my sunglasses are not women specific. So, if you tried their WS sunglasses, you might find a good fit. By the way, I wear mine on the outside of my helmet. The plastic thin part that touches my head. (Hope that makes sense.) This is, apparently, how Dh says they are supposed to be warn.
