Do you have a specsavers near you?? If so I would recommend them highly. I have had great service from all of them, and they have a great range at cheap prices. Otherwise "budget eyewear" may have some cheaper but still decent looking glasses.

FYI - think yourself lucky you only have to pay for normal lenses - I am so shortsighted that I have to pay approx $300 for my lenses and then pay for the frames on top of that.
