I don't know much about Oakley as i can only get my prescription into Rudy Project sunnies.

I would try and pick up a few differnt coloured lenses for dark, shady & sunny times. If you mtn bike, the orange lenses are great! When i leave at 5am for a ride & it's still dark (I keep my spare glasses at work so i don't have to carry lots of stuff when i ride) I have my clear lenses in my sunnies. I then have my other lenses in my ground effect pouch thingy.
