    How long do AR coatings last?

    I've had two pairs with Crizal Alizé be perfectly fine and suddenly wear out quickly after almost exactly 5 years. What gives? I don't think they've been near too much heat, at not after exactly that much time.

    You can see it all around the rim but dings and dents also tend to leave a mark more easily.

    How long did your oldest pair last and what AR coating did it have?
