If it were my money, I wouldn't waste it on Oakley. I've worked at several optical shops and was a lab manager at a Pearle Vision. The quality of Oakley product is not up to par with other brands costing half the price. Little do most people know that to get your Rx Oakleys. it takes up to ten weeks!
That's pretty bad service. Most decent retailers can fit a Rx into a quality opthalmic frame for under $300.00 depending on Rx.
The best route in my book, is to find a zyl (plastic) frame with a lot of wrap. Find a polarized lens (brown polarized is a great tint for riding.) It makes scenery like grass and trees more vivid. Polycarbonate is the best choice for impact resistance. You wouldn't want a glass or plastic lens breaking if your hit by a stone while riding. (Though I wear glass, purely for optical clarity.
Backside anti-reflective coating is great to cut glare in combination with the polarized.
I would choose a well made frame from Rudy or Porsche, or Rayban, and choose the options I recommend above to fit your needs. Just avoid Oakley your paying for their marketing, not quality.
P.S. Their awesome "plutonite lens" that they claim is so special... standard polycarbonate lens blanks. About $3 wholesale. Think about it???
