For the warranty, Oakley only offers 1 year against
manufacturing defects if you buy from local authorised retailers
where you will get the receipt together with a stamped warranty
card. My Oakley glasses do not come with the warranty, however,
buyers can always make thorough check on the glasses before closing
the deal. It is never easy to spoil a pair of Oakley and I am sure
you will take good care of such an expensive pair.
Thanks.
