if you want fashion or function is what you need to decide.
good sunglasses that will do what you want: oakley: jawbone, split jacket, flak jacket, half jacket, half jacket 2.0, fast jacket, radar series.
i think the jawbone, split jacket, fast jacket, and radars are your best bet since you get two lenses with them but you also pay the price.
glasses that will look great but wont stay on your head: oakley: dispatch, Jupiter, jury, frogskin, holbrook, fuel cell, pretty much anything under lifestyle on their website will not have rubber on the ear stems or nose which will cause the glasses to "fall" down your face.
so if you want to look good, you are going to sacrifice performance.
