Where to buy discount prescription eye-glasses?

[bifocal eyeglasses]

I'm looking for a place to buy some discount eyeglasses. Like most products in China, shops tend to concentrate in particular areas and I was wondering if anyone knew of any such places selling eye-glasses. I've seen pairs for around $100(lenses, frames, all inclusive), which I consider a pretty good deal but I was just wondering if others have other experiences. Thanks a million for any suggestion.

You can try some online shop such as Buy Cheap Eyeglasses Online: Discount Prescripton Glasses Direct maybe that's a nice try for you, prescription glasses start from $7.95, and you will find other good-looking glasses with high quality at a discount price.
