This is one of my only main complaints with Oakley lenses, is that they don't do AR coating. I have a pair of Maui Jims, Persol, and a few RX lenses all of which feature an AR coating noticeable as a blue or green tinted slightly reflective coating on the inside of the lens. But most Oakleys (at least the sport models I use) tend to let so little light in from the sides that it's rarely an issue.
