But these are completely different devices, these are sold for 330 Euro here, which on one side is a lot of money, but on the other they are not that much more expensive than any "normal" designer pair of sun glasses. If any "influencer" will start using them you can be sure that everyone will want them, and they will become a way to show off not unlike the latest-latest iPhone or similar fashion items, and if they become common enough they will be misused.
