"b+" stamped on lenses? - Bolle Silium Safety Glasses

I find it hard to believe that you are actually interested in my opinion on this product since I sent 2 emails concerning this purchase directly after I received them and they went unanswered. The glasses came with a "B+" stamped on each lens, which is not in the picture. It's just a nuisance and makes me wonder if these are factory seconds.
Pros: Well made glasses that wrap snuggly around my face. Solid construction with good ergonomics.
Cons: Your customer service doesn't answer customer emails.
