They are available from some time in Germany also. And here they don't say they come from Japan (but from other asian country, korea i think) so the article reads like cheap propaganda.

Do you have a link to where they can be bought from in DE? Or the brand name?

They are called something like"myo smart glassses" or myo smart. They are available in Ingolstadt at "Sichtbetont". Also the Augenklinik from the LMU München can AFAIK recommend some suppliers.
