Buying Glasses Online
If you have thought about purchasing your next pair of prescription eyeglasses online, there are a few things you need to know.
Ordering eyeglasses online may seem easy, but it is very different than ordering your average consumer item. It is important to know that your optometrist is trained in the proper fitting, measuring, manufacturing and dispensing of eyewear. When ordering online, the consumer is, in essence, taking on the role of a trained optical dispenser. This includes taking critical measurements and making critical decisions with respect to frame, lens and material selection. There is an inherent risk associated with making these determinations without the proper skills and education. Your prescription given to you by your doctor of optometry is only one piece of information that will determine how well you see with your new eyewear. During the normal process of selecting and getting properly fit for your new eyeglasses, your doctor of optometry is determining a number of things to make sure your new purchase is custom made to give you clear and comfortable vision, while making sure you look great, including:
Accurately measuring the distance between your pupils so that your new lenses will be properly located in the new frames relative to your eyes
Selecting the right size of frame for you
Selecting the right shape of frame for you
Determining what curvature of lens to use
Determining what type of lens material to use
Determining what coatings to use on your lenses that best suit your needs
Determining the height to place the optical center of the lens in your frames
Measuring how high to place the bifocal or progressive (if you wear a multifocal lens)
Properly adjusting the frame to your face
If all of the above are not chosen specifically for you, it’s not uncommon to have problems that begin immediately or develop after using your new eyeglasses for an extended period of time. Common complaints regarding improperly ordered or fit eyewear can include headaches, fatigue, an “eye pulling” sensation, nausea, and pain or pressure marks on your nose or around your ears.
