I have tried several other glasses and always had the problem that it takes somewhere in the eye. But the days are gone! I have (with the bright-orange glasses (black 331) here) bought me a year ago, the Alpina Drift in a Sprotgeschäft and am highly satisfied! Well I bought the same model with the very dark glasses here. I am more than happy with both! In the other reviews is that the glass from the frame triggers that I have not yet happened. Only if I drop the glasses or press them together in his pocket.
