because I have the glasses not worn until now, I am for the time being careful with this bewertung.von optics, comfort and handling at the moment I would give 4 stars which is to consider price. 2 small drawbacks, which is blue in the photo has more bluegray what I liked better. In reality, the glasses in a more vigorous blue which is not necessarily bad, but rather something more daring aussieht.die brackets are glued and not screwed so I can not say as yet whether they stood hält.also just so in a bag reinlegen probably not in it seems to sein.es looks like as if treating these glasses like a raw egg to muss..nach bear at least 10 times I will again post an update unless the glasses goes before zubruch.UPDATE the glasses was worn 3 times and is far good.The glasses are not too dark and the comfort is also okay. the design with the checks is extraordinary and not common so it Like mir.die glasses is not very sensitive but you should give it in an envelope or wear on his head instead of bang shut in a bag, if they are not even on the nose bears. if you treated them with excessive caution it does not go well to break as many of described herein. I would continue to be awarded 4 stars.
