The thing that’s extra nice about the Ray-Ban Aviator Folding Ultra Limited Edition Collection ($480) is the fact that they fold up. Don’t you wish other things would fold when you wanted them to? An unruly slice of pizza; a stubborn bed sheet; the Yankees. None of these things fold on command the way these glasses do. They also come in crystal green, blue and brown P3 Plus lenses, to go with silver, yellow and gold-plated frames.
