I had been seriously shopping for a pair of folding glasses for some time to toss in my pocket to use at restaurants and the like.  When I saw a news segment about these glasses I immediately came on to Amazon and, Lo!, there they were. Mostly, I think these things are great. I bought the &#34;universal case&#34; and simply carry it in my pocket for the times when I'm without my reading glasses (restaurants, in a meeting, on a plane, etc.). I've never gotten the impression they are to be considered replacements for ones regular reading glasses and they're not.  With that said, they sit comfortably and firmly on my nose and I never feel like they are going to slip off and, at the same time, they are light enough to be comfortable to wear for longer periods if need be.<br /><br />With that said, my one complaint about them, and this is why I only rated them 3 stars, is that the lenses have scratched quite noticeably.  I've been using these glasses for about a month now and most of that time they are in the case in my pocket and, still, they are pretty scratched up. I'm not sure if there is some lint/dirt from my pocket making its way into the case and causing the scratching or what the issue is. When I read the product description, I read &#34;shatter-proof lenses&#34; as &#34;scratch resistant&#34; as well - apparently that isn't the case.  As another reviewer mentioned, maybe lining the case with felt or some other material would mitigate the issue.<br /><br />Overall, I would, and still do, recommend these glasses to people, but now caveat my recommendation with the warning about scratching.  If they get a handle on the scratched lens issue, this would be a 5 star review, no questions asked.
