Glasses tint peeling

I noticed 2 days ago my Oakley glasses has the tint which bubbled and looks like it's cracked but its not.I have went into sunglasses hut and because the glasses is 3 years old it's not in warranty anymore and they have to provide a quote however this seems to be a common issue after I looked at the exact same situation with another customer.is Oakley ripping us off where the tint on their glasses starts to peel after the 2 year warranty period .I have owned many Raybans and no such issue .I think this needs to be investigated as others have the similar issue ...doubt I would buy or advise anyone to buy this brand .
