Over the years, I've been buying my glasses from HK Optical, Optical 88 and the like. But I'm told that some places offer a huge discount on designer frames and that I'm a sucker for paying Central prices. One of my colleagues paid $600 for his frame + lenses! He said that there are places away from the street front and you find them through the touts handing out flyers, but he couldn't tell me exactly where to go. Any ideas where to find such deals?
