My wife loves the Vonzipper Alta Farva sunglasses. She has trouble finding sunglasses that sit well on her petite nose. For example, "asian fit" Oakley's still rest on her cheeks. These fit like a charm for her (and are great on my much more protruding sniffer).

Performance-wise, the lenses perform in a wide variety of light conditions. They even do pretty well backcountry skiing, though mostly she uses them for driving and wearing around town.
