S.C.
We have no insurance and several of us wear glasses, so we go to America's Best. Here is alink:
For $70 you get two pairs of glasses and that includes the exam, frames, and lenses. They even have a kids' package that covers accidents. You can also upgrade to any of the extras you want like tinting or transitions or designer frames. Anyhow, we have been going there for years and they are a great deal.
