Had my last pair for 5 years and would have had them longer if I did not leave them on the side of the road. They last forever compared with more expensive glasses and love the lenses that change with light conditions.
I purchased the clear-to-black photochromic replacement lens to utilize for most of my riding time in the fall/winter/spring of southern Oregon. I love how easily lenses can be replaced in the Oakley Jawbreaker glasses and the photochromic lens covers every base of my riding....sunny, cloudy, foggy, rainy, no matter what the weather this lens provides just the vision I want. This might end up being the only lens I will use year round. While the photochromic change in the color of the lens can never be instantaneous, I never notice the change in lens color...it just happens and it always appears to be just right. I love these lenses and glasses!
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.
