Today, it seems as though you can buy almost anything online as the internet continues to expand and bring a new level of convenience to the shopping experience.

So it’s no surprise that you can now find prescription eyeglasses for sale online and if you have thought about purchasing your next pair online, there are a few things you need to know.

Your prescription given to you by your optometrist 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 eye care professional 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. Some of those things include:
 

  1. Accurately measuring the distance between your pupils so that your new lenses will be properly located in the new frames
  2. Selecting the right size of frame for you
  3. Selecting the right shape of frame for you
  4. Determining what curvature of lens to use
  5. Determining what type of lens material to use
  6. Determining what coatings to use on your lenses that best suit your needs
  7. Determining the height to place the optical center of the lens in your frames
  8. Measuring how high to place the bifocal (if you wear a multifocal lens)
  9. 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 may be immediate or come on after using your new eyeglasses for an extended period of time. Common complaints for 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. Eyeglasses are the traditional method of correcting vision problems. They can correct almost all common vision conditions. They are available in a wide array of fashionable styles to suit many lifestyles.
