Mirrored visor legal ?

Hi, I ordered the following in connection with an HJC FG-15 on Saturday in the Polo Online Shop:http://www.polo-motorrad.de/…-antifog-blue-reflected-56035.html I wonder if the visor is also legal, since there is a package leaflet on which it says that the visor can only be used for race tracks or for decorating purposes and not for public road traffic. However, the description says that all colours are allowed, unless they are strongly toned. On the polo page there is this visor also as strongly tinted, which I did not order. My question is whether someone uses the same visor and if he can tell me that you can also use the visor – of course on the day – in traffic. Thank you in advance.
