I did some research and found out that Jamie is probably wearing Swissflex glasses. I would love to have a pair myself so I looked up some stuff and heard someone on a forum say that they're nigh invulnerable. That he stepped on them, dropped them on concrete, put 'em in his pocket with keys, et cetera... and they aren't bent, scratched, or broken. Are they really this strong, and do they really weigh only 2.5 grams?
Oh and as a side note, I live in western Washington, how do I find out how to get me a pair???

they also render women's clothing transparent.

If it were Adam's glasses I might agree, but Jamie seems like the kind of person who wouldn't be as amused by that.
