Since the glasses has a continuous tone and Category 3 is, one must still take their car. But I would only do this in the sunshine, because by the strong tint it is otherwise with a few clouds in the car too dark.
The glasses are nickel free, which I find very good. The joints of the glasses have a screw, with which they can be possibly made tighter. The joints are spring-loaded, so can also be easily pushed outward. Otherwise, the processing is simple, but absolutely fine.
The dark tint goes well with an aviator glasses, his eyes are only vaguely visible. Who is looking for what abchecken, should choose a colored mirror coating - can not be seen by the eyes ;-)
