Try Costco -- my last pair of eyeglasses from my ophthalmologist's office were $300+ (and I was re-using my old frames!)
I just got progressive bifocals with thin lenses and no glare and every other option as well as prescription bifocal sunglasses with all the same specifications for $450 total at Costco. VERY happy.
I have a pretty complicated prescription, so I was concerned, but everything worked out great. They have an optometrist on site, but I already had my scrip from the doc, so I dealt with the technician at the counter who took all the measurements and placed the order. They were ready within a week.
The frames were pretty much all <$125, and most under $100 -- designer names.
