Very strange, I had previously bought the same pair and this pair just seemed different in a number of ways:<br /><br />1. The construction seemed far more flimsy than the previous version I bought<br />2. There was a serious amount of &#34;haze&#34; in the lenses which was not present in the previous one I bought. I tried cleaning them and it didn't make the haze go away, so it appears to be something about the lenses themselves.
