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
As a consumer, you have a number of choices when it comes to purchasing eyewear. Working with your optometrist from the initial optometric eye exam to the final fitting will ensure you receive accurate, quality manufactured eyewear that is best suited for your eyes and your lifestyle.
