I've had my current Oakley frame for almost 6 years. Still looks new, so I picked out another Oakley frame. When I'm picking lenses for it, I have two options 1. $233.95 Hi-index 1.67, Transitions, Crizal coating or 2. $350 Oakley plutonite, transitions, Oakley AR coating I got option #1 last time and they have held up perfectly. Do I spend the extra $120 on Oakley lenses? Anyone have experience with them? Is Plutonite that much better?
