The holder of glasses sitting on the lenses, which is significantly in Sichtbereicht. I felt as if the glasses on the inner edges very dirty which makes it impossible to use for me.
Likewise, the glasses are in several places poorly sanded and put through this I can only see blurred. One then has the feeling not to wear his glasses. If I want to see only blurred contours, I can from my glasses, and only one 3D glasses put on.
My advice: Stay away, stay with a second spectacle or waiting for a better version, this is good here in my view (and even at such a price) nothing.
