8 Reasons to Avoid Online Glasses

Have you considered purchasing cheap glasses online? Or maybe you’ve been tempted to buy cheap sunglasses at a mall kiosk…or cheap reading glasses at a discount store?

After all, why should you pay hundreds of dollars for prescription eyeglasses when cheap glasses look every bit as good, right?

As much as we all want to avoid spending hard-earned money unwisely, deals that seem too good to be true when buying glasses are no different than deals that sound too good to be true when buying anything else — you may save money up front, but the product often doesn’t live up to your expectations.

And when it comes to eyewear, some cheap glasses can actually cause harm to your eyes that you’re not even aware of.

Being a wise eyewear consumer requires a little due diligence to understand factors that affect the quality and value of eyeglasses and sunglasses.

Here are 8 things to be aware of if you’re considering cheap eyeglasses or sunglasses:

1. Know what’s being cut to offer lower prices.

Online retailers that sell cheap eyeglasses and sunglasses often say they can offer low prices because they don’t have the same expenses associated with a “brick-and-mortar” store, such as the high rent paid in retail shopping areas.

But what they often don’t tell you is their lower prices come with a hidden cost — you no longer get the personalized attention and fitting expertise of a qualified optician. That’s a huge part of the value equation.

Instead, you’re on your own to select a frame and lenses for your cheap glasses and hope for the best.

2. Beware of claims of “same top quality.”

Sellers of cheap eyeglasses and cheap sunglasses are quick to claim they are providing glasses of the “same top quality” as eyewear you purchase from your local eye care professional.

But how do they determine that?

The fact is, there are significant differences in the scratch resistance of different lenses and lens coatings, different levels of optical performance among different lens materials and brands, and different levels of comfort and durability among different frames — even among frames with the same brand name.

Also, many online retailers who sell cheap prescription glasses fabricate the lenses in their own optical labs rather than using a wholesale optical laboratory that specializes in providing this service to eye care professionals. And while this might help you get your cheap glasses quicker than eyewear purchased in an optical store, in some cases quality of the finished product may suffer.

3. A bigger selection often isn’t a better selection — it’s just more confusing.

Online retailers of cheap glasses point out that optical stores cannot match their vast virtual inventory of frames. This may be true. But how many of those hundreds or thousands of frames are a good fit for your head and face shape? And who will help you choose?

4. Virtual and home try-ons can’t insure satisfaction.

If you’re buying cheap glasses online, you often will have access to a “virtual try-on” feature — where you upload a forward-facing, closeup photo of yourself and you can then superimpose images of different frames on your face to see how they look.

But while a virtual try-on can give you a rough idea of how you’ll look wearing different frames, it can’t tell you anything about how the frames will feel. It also can’t demonstrate the detailing and workmanship of the frame.

Also, depending on the quality of the virtual try-on tool, the size of the eyewear might not be accurate — the frames might look larger or smaller than they actually are. And it’s not unusual for the color of the actual frame to look noticeably different than the color shown online.

Even if an online retailer sends you a sample of frames to try on at home before you make your final purchase, you won’t know whether the glasses will be too heavy after the prescription lenses are added…or how thick those lenses will be. This is especially important if you are sensitive to the weight of eyeglasses because you have sinus problems or delicate skin.

All these potential problems can be avoided by being fitted with glasses in person by a skilled optician.

5. Cheap sunglasses can do more harm than good.

Cheap sunglasses sometimes look nearly identical to premium quality sunglasses. They can even seem to provide equal performance in bright sunlight. But they also can be doing more harm than good.

The level of protection sunglasses provide to shield your eyes from the sun’s harmful ultraviolet (UV) rays has nothing to do with the color or darkness of the lenses. And it’s impossible for you to feel how well your eyes are being protected from these damaging rays while you’re wearing the sunglasses.

So it’s possible for two different pairs of sunglasses to look (and even feel) the same, but one is providing a much better level of eye protection than the other.

Cheap sunglasses — even those labeled “polarized” and “100% UV protection” — often allow harmful violet (“near-UV”) and blue light to penetrate the eye and potentially cause damage over time.

Your eye care professional can explain which trusted brands of sunglass lenses offer the best protection from harmful rays and the preferred visible light transmittance for your outdoor activities and visual needs.

6. Cheap reading glasses can cause eyestrain — or worse.

Cheap reading glasses sold in discount stores can help you see more clearly up close if you’re over age 40 and experiencing the normal age-related loss of focusing called presbyopia.

But it’s easy to choose the wrong power, and the optical quality of cheap reading glasses typically is not as good as a customized pair of glasses for computer use and reading.

Also, cheap reading glasses often provide no protection from high-energy blue light emitted from computer screens and other digital devices.

7. Cheap eyeglass frames can cause skin irritation — or worse.

At first glance, some cheap eyeglass frames may look like more expensive frames. But often, they are made of low-grade materials that can cause skin irritation over time. Cheap plastic frames can get bleached by UV rays and the finish can roughen after a few months of wear. Cheap metal frames often contain nickel alloys that can cause skin irritation; others can discolor your skin.

Also (and more disturbing), cheap eyeglass frames and cheap sunglasses occasionally are recalled and removed from the market because they contain lead paint or other toxic substances.

8. Can you be sure sellers of cheap glasses will be around tomorrow?

Warranties on eyeglasses and sunglasses are only as good as the reliability of the retailer who provides them. Can you really trust an online start-up or mall kiosk to honor a warranty on their cheap glasses and sunglasses?
