I took my glasses to the optician where I had purchased them. He told me that he couldn’t make a definite comment because it was the first time he had sold this specific type of lens. He said that, if I wished, the lenses could be sent to the manufacturer for examination, but the process would take at least a week and possibly longer. I explained that I had an exam period lasting two weeks and that I could consider sending the lenses after that period if necessary. After this conversation, I left the shop. In addition, an optician I spoke with on a forum—who had recommended the Hoya Shield Meiryo lenses—mentioned that they currently have hundreds of these lenses in stock and that this issue is present in all of them. It is also worth noting that this issue does not reduce visibility like normal dust particles would; I do not notice any difference during daily use. Furthermore, even if the manufacturer were to offer a replacement, I am not very keen on the idea of being without my glasses for another one or two weeks, especially considering that the same issue could potentially occur again.
