Several CNET editors have bought their glasses on Warby Parker, which has a good selection of sharp-looking eyeglass frames. While glasses start at only $95 with a single-vision prescription, chances are you're going to pay a bit more -- around $150 to $200, according to my colleagues -- based on the type of frame options you choose, your prescription and type of eyeglass lenses.

Be aware that sometimes optometrists won't give your pupillary distance because they'll say they want to measure you for a specific set of glasses. Pupillary distance is key because when lenses are made it's important to know where your eye is in relation to the center of the lens. But insist on getting one. You'll need to know your prescription and pupillary distance from your optometrist before you use an online glasses retailer -- so make sure you get a hard copy the next time you get your vision checked.
