I have this beautiful Oakley Whisker sunglasses that are prescription lenses. I've babied them ever since I got them. BUT both lenses are showing a delaminate of the inside coating. Lencrafters will not fix them. a replacement set of lenses is north of $360. They are about 4 years old with no scratches or blemishes. Any chance that Oakley can fix this defect? If this is common, then my next pair wont be a set of Oakley's.
