Buying Eyeglasses Online

If you've ever ordered products online, you know that the Internet nearly always beats a regular store hands-down for convenience: you never have to leave your house! Plus, with just a few clicks of your mouse, you can comparison shop for a great price.

However, you need to consider certain issues when you buy eyeglasses online, because every pair of glasses is a custom-made item. Not only are there different designs and materials of both frames and lenses and different lens treatments, but everybody's head and eyes are different, too. So you or an optician must make various measurements for a proper fit.

An advantage of going to a traditional optical store is that an optician can walk you through the process. Sometimes, he or she will do this so smoothly that you're not even aware of all the choices. When you order online, you have to make each decision on your own, and it can seem overwhelming.

Most online eyewear providers feature a catalog that shows the frames they offer in detail. You can view each available color and read a description of the frames' features, such as what material they're made of (plastic or metal, for example), or whether they have spring hinges.

You also need to decide what lens material and which coatings, if any, you want. Are polycarbonate, high-index or regular plastic lenses best for you? Do you need ultraviolet (UV) coating? What about an anti-reflective coating? Is a tint a good idea?

If you're comfortable making these decisions yourself, you should have no problem with online ordering; if not, you may want to ask an optician for help.

The optical center of your eyeglass lenses is the part that gives you the truest vision, and it should be directly in front of your eyes. To determine how to place the lenses in your frames so the optical center is customized for your eyes, the eyeglasses lab needs to know the distance between your pupils, or PD.

It can be tricky to measure your own PD: it is somewhat akin to trying to cut your own hair. It takes dispensers lots of practice to be able to calculate PDs correctly, and even experienced opticians have difficulty taking their own in a mirror. Most online optical providers present you with several ways to go about this important task. Some suggest the simplest method, which is to have your prescribing eye doctor or an optician take the measurement for you. Alternatively, they offer step-by-step explanations of how to take your own PD in the mirror, or how to have a friend take it for you.

The way that eyeglasses fit your face and head is another issue that's important. Frames that are too large or that don't fit the bridge of your nose properly can slip. Not only is that uncomfortable, but you can also get a headache if you're not looking through the optical centers of the lenses.
 

Alternatively, if your glasses are too small, they will be uncomfortable to wear; they can pinch the sides of your head and leave red marks on your temples. They can also hurt you behind your ears or on your nose.

It can be challenging to try to fit yourself with eyeglasses, but some online stores offer tips. One site suggests that you select eyeglasses in a size that is close to your current glasses, or that you measure your head with a measuring tape or use your hat size as a reference.

It's important to note that prescription strength and the weight of the lenses you require also play into whether eyeglasses will be comfortable. Many times, an experienced optician is a good judge of whether the frames you love will work for you, or whether they will cause you problems once the lenses are inserted.

When you shop in a traditional optical store and want to know how a pair of glasses looks on you, you simply try them on. Optical websites offer creative solutions to address this important issue. Eyeglasses.com, for example, allows you to upload a photo of yourself to the site, and then superimpose the image of the frames you're interested in on your picture — a process they call TryItOn. Other sites offer tips on getting the right look by describing different face shapes and recommending styles of frames to complement each.

Bifocal lenses present an additional challenge. Fitting bifocals is an intricate process because an additional prescription power is added to the lens, and extra measurements must be taken. Most sites shy away from offering bifocals, although some give shoppers the option of contacting them via e-mail and going through the process on an individual basis, rather than by filling out a form.

Bifocals also come in many different styles. Determining which one is right for you often requires an in-depth discussion with a knowledgeable dispenser or doctor. Even if you already wear bifocals, if you are limited to just certain lenses on a website, you might not find out whether you're getting the optimal lens for your visual needs.

Some of the companies that offer web-based optical goods post their return policies on their sites, so that if you find that the glasses aren't right for you, you are entitled to some sort of refund. These policies seem consistent with what is offered at brick-and-mortar optical stores. Naturally, if you return a pair of eyeglasses that has been mistreated or is missing parts, you probably won't get much of a refund, or any at all.

In many ways, it is easier to select eyeglasses if you have an optician helping you.

However, counterbalancing these limitations of purchasing eyewear online are the benefits of convenience and price. If you already know which frames you want to purchase and have measurements taken by an optical professional, it can be a delight to sit down at the keyboard to order your new eyeglasses and wait for them to arrive in the mail. Certainly, those who have difficulty traveling, are in remote areas, or are just plain busy appreciate this option.

The bargains that you can get online can be attractive, but it takes a bit of work to make sure you're getting a good deal. Just as with any other product, a little comparison shopping by telephone, in person or at other websites can be valuable.

Like the eyewear itself, the decision whether to buy online or not is very individual. If you decide that buying eyeglasses online is for you, arming yourself with as much information as possible beforehand will help you get the most out of the experience.
