This can be very good info and save you money!

That is probably what the optician was going to do.

Sweet, I'll be trying this. I'm on a second pair of Oakley RX whose anti reflective coating has been removed at the tops where they touch my brow. I was wondering if it was the sweat or the sunblock. thanks for the info.

mknoyce, I hope it works for you. I'm still wearing the ones I removed the coating from and my lenses are still clear. When I tried this it was at the point of, "what do I really have to lose?". Since everyones lenses may be made of different material as well as the coating, people should try this as a last resort.
