Hi there, thanks for your response. I have now sent the sunglasses back to the supplier for a full refund. On a side note, I purchased a pair of Deadbolt approximately 12 months ago with the exact same problem on both sides but I thought Oakley may have the problem sorted out by now.they were purchased from different suppliers from different countries. I have been purchasing from both suppliers since early 1980’s but I won’t be purchasing Deadbolt again.
