Glasses have gone urban. Club kids, rappers and hipsters are all wearing funky frames. "A few years ago, everything was vintage," says an Optical Innovations employee. But that's not true anymore. Optical Innovations carries lenses too cool to find at your eye doctor: plastic frames, titanium frames, rhinestone-studded frames, tinted frames, rimless frames, cat's-eye frames, tiny frames, jumbo frames, buffalo-rimmed frames, round frames, square frames, octagonal frames. Theo glasses come from Belgium, featuring clean lines and eye-popping colors in shades of chartreuse, purple and pink. "Those are really crazy," the clerk says.
