What kind of lense is used for 20/20 vision?

I am waiting for new glasses. I have a very odd case of having one eye that is 20/20 and another eye that is really bad ( can't remember what number ) I only need a perscription for the one bad eye, i was wondering, what kind of Lens will they use for the 20/20 eye? Will it have any kind of perscription? Or will it just be a piece of glass?
