I bought a very expensive pair of Oliver Peoples Glasses. After about 6 months I noticed that the lenses were developing a defect. I sent the glasses back to them to get new lenses under the warranty. They happily replaced the lenses but after only a few weeks I noticed that the lens defect was happening again, basically, there is a misty part to the lens appearing in the top corner. I contacted Glasses now about 4 times and never had a reply to my emails. I have worn glasses for 30 years and this has never happened to any other lenses I have, I will not be using them again as I believe their lenses are substandard.
