Yesterday I found a man with a pair of folding eyeglasses, I thought that was pretty cool, you only need a piece of space to place it, so where can I buy this kind of eyeglasses? Better if cheap ones!

I don't kown where can you get this kind of eyeglasses, but I suggest you don't take into account of them, one friend of mine has ever wore folding eyeglasses, but it can easily go distortion as long as the spring hinge get loosen.

Yep ,cool design,I think it`s must very suitable for those who work in the special areas that the space is limted or the light density changes frequently.Thanks.
