Okay, so the blog is called "Glassy Eyes" and they have links to tons of websites. The site where "Erica" got her great glasses is called "Zenni Optical". Here are some faves from there.
For ten dollars you are allowed to follow the big nerd glasses trend. I give you permission.
These look a lot like the glasses I already have but they were no where near being $12!
These are math-teacher-chic and for all of you who want to look like an American Apparel model but don't want to spend the moolah, these $8 glasses are for you.
These are $30 with the prescription and the frames, but really, can you argue with that?
Oh, and just so you know you have to look at the measurements and make sure they will work because I do not think they can be returned. But for 10 bucks it's no big thang.
