Maybe. If you look through the history of Oakley they had huge quality control issues all over the place. They are known for good quality polycarbonate lenses and impact resistance but high level daily durability was not something most would associate with Oakley, especially with their easy-to-scratch lenses. Similar to your story, Oakley has had issues with coatings all throughout its history. They still couldn’t get consistency on their FMJ coatings even after a couple decades which is why you do not see them around these days. Coatings on the X-metals took years and a couple generations to fix. The coatings on the Mag stuff was atrocious. That is not even including all the other issues including problems with spring hinges, O Matter getting brittle from the pre-1999 formula, spider cracks on some frames like the Riddle and Romeo, etc.
Maybe I’ve just been exceptionally lucky then. I did have an FMJ issue and one broken frame after 5 years of use, but I’ve had more hold up for many years of hard use. To be fair all that have been solid have been Pro and regular M Frames.
