The Alpina mastered changing light conditions well. However, it always takes a few seconds until the tint is adjusted. I notice, for example, when I go from a forest in the sun and initially feel dazzled. But I got used to it. Rather unnecessary I feel the inclination adjustment of the bracket, especially the grid is quite smooth and the strap adjust unintentionally quickly. In the "normal setting" fits my glasses perfectly. In addition, they do not fog up.
Unfortunately, there are quite bulky glasses for no storage case, but only a ridiculous bag. Therefore, a star deduction, otherwise a great lightweight glasses, which works very well in practice.
