Another option is to buy from eyeglass websites. Doing that, we were able to save as much as 40 percent, compared to buying at a walk-in optical chain store such as LensCrafters.

The downside, of course, is that you have to wait for your glasses to be mailed to you, and it can be a hassle returning them if there's a problem. But if you don't mind paying more, or most of your purchase is covered by insurance, go for independent local optical shops or a private doctor's office, which got high scores for satisfaction from our readers and top marks for merchandise quality and customer service. If you want or need your glasses in an hour or so, be prepared to pay for the privilege. LensCrafters was, by far, the fastest place to get new specs – almost half our readers who shopped there had their glasses the same or next day. But it also was among the most expensive. The readers who responded to our survey spent a median of $244 out-of-pocket on their last pair of prescription specs. They gave Costco Optical the highest score for overall satisfaction among chains, with other discount retailers, including Sam's Club and Walmart, getting decent scores, too. Frame selection was the only category in which these particular discounters didn't get high marks.

So if these discount stores don't have that frame you want, consider shopping online. and reading the how-to information. Knowing something about the types of frames, lenses, and coatings available can help you understand your options and sense whether a store or website is trying to sell you more than you need. You might even upload a photo of yourself and use the virtual try-on feature on some sites to get an initial idea of which frames look best on you. Talk to Your Doctor If you're having your eyes examined (which you should do if you prescription is more than a year old), talk to the eye doctor about which lenses are best for you. Also discuss add-ons, such as anti-glare coatings. If your examination is at Costco or another discount store, check out the frames. If you find one or more that you like, you may not need look any further. If not, try a couple of other walk-in stores, noting the brands, models, and sizes of the frames you like. You'll find that information marked on the frame's temples.

They offer a complete pair of single-vision glasses for less than $100. And, depending on the site, you can even have multiple frames mailed to you so you can try them on at home. But these sites primarily sell their own proprietary frames not available elsewhere; so you won't find frames you saw at a store or another website. Unless you're interested in a proprietary frame, search the web with the brand and model number of your top picks to see if you can find better prices. If you plan to buy your lenses online as well as the frames, check the sites' lens prices as well. If you don't feel comfortable ordering lenses online or if you have a complex prescription or one that involves multi-focal lenses, you can still save by purchasing the frames online and having the prescription filled at a local discount store. Once you find the best price, go back to the walk-in shop where you initially saw the frames and find out whether it can meet or at least come close to your top deal. And keep in mind that buying your glasses at a walk-in store makes it easier to return them if there's a problem.
