My only issue with this is...
I really don't want to wear glasses all the time. I mean, I guess I wouldn't have to wear them all the time. It would be kind of cool for concerts, but at the same time, I would hate to loose them or have them fall off while jumping around listening to music. Good idea, I just have never thought people would want to wear glasses. I mean, look at Google Glass.
I personally don't use Snapchat. Most of my friends do, I just dont see the need to be tied into another social network, but putting that aside, even if these were for Twitter, I don't think I would be vey interested in them.
