After less than a year of light use, discolored rings started to appear on my green polarized lenses. I sent them back to Luxottica and ended up paying for the repairs.

After waiting for about a month, I decided to send them an e-mail asking for the status, it took them 3 days to reply.

Another month goes by and I finally receive my "repaired" sunglasses.(BTW, they do not provide you a tracking number)

2-3 months goes later and BAM THOSE DISCOLORED RINGS APPEAR. I searched around and turns out that other people have had the same issue as I have: [...]

This time they tell me that it is a manufacturer's defect and that they will replace it with no charge...SO WHY DID I EVEN HAVE TO PAY FOR IT THE FIRST TIME?! THEY WERE THE SAME EXACT PROBLEM.

I called them up and the representative (who BTW did not even tell me her name and was very rude) told me that during the first repair the lenses were replace due to scratches! ARE YOU KIDDING ME?! I SENT THEM A SUMMARY REGARDING THE DISCOLORATION AND ON THEIR SYSTEM THEY PUT SCRATCHES?!
