UPDATE 2: Finally got response after posting to Luxottica's Facebook site wall. Eventually mailed new glasses and charged $25 handling fee--- feel like I had to twist their arm to do the right thing, so upgraded 1-star-- End of the day, not worth the 8 months it took to get this issue resolved.  UPDATED: Within warranty period, a small hairline crack emerged from within one of the lenses. The lens seemed intact except for the very fine crack. This took place with normal use during a cold winter day while outdoors-- glasses have never been dropped. I've had several Ray Ban glasses over the years with no issues until now (most were lost while boating etc). Contacted Luxottica which refused to honor repair alleging it was not a manufacturing defect. Customer requested additional review which after 4 months came back with same result. Luxottica sent a letter offering to repair for $70, but I have been unable to reach Warranty service at 800-343-5594 despite repeated attempts over the past 2 months (now totaling 6 months of effort to resolve this!). Emails initially took weeks to receive response, but in recent weeks I no longer receive any response (consumerwarranty@mailmw.custhelp.com). Filed BBB complaint for lack of compliance with terms of the Warranty and poor customer service (an unheard of for Ray Ban) support. At this point I've lost hope in getting my sunglasses (even in its current condition) back.  Best sunglasses ever, great for motorcycle riding with the Polarized glass lenses-- won't scratch or break
