Buying glasses is the trickiest part of the equation. You can't change spectacles like socks—you're stuck with whatever style you choose, planted on the crest of your nose like a harbinger for your social life. Our advice? Stick with a style that's worked for other folks, one that's stood the test of time, because the last thing you need is the eyeglass equivalent of shoulder pads or leisure suits on the face. FrameGeek, a new blog highlighting the vast array of options in eyeglasses, has made a handy reference poster of styles that won't be a flash in the pan. Print it out and bring it along the next time you're shopping for specs, although we can't guarantee that Lenscrafters carries frames like the Dame Edna or Bootsy Collins.
