Top notch "barely there" sunglasses that work well in any condition. It is incredibly light weight, sits on the nose and temple softly, has no frame to obstruct the view....so practically you can forget that you are wearing anything. Except that you see better in rain, shine and shade. I have been abusing my first pair and still works like new. No matter how aero the position, when I look up I never have to look OVER the lens, always through, so no wind and bugs hit my eyes either, which has been an issue with smaller lenses.
The Oakley EVZero Sunglasses are super lightweight. The Prizm lenses give you great contrast and are very clear. I love the frame less design it gives you a great field of view of the road.
