Ask An Optometrist

  Question:

Why would I buy in store when I can buy cheap eyeglasses online?

Answer: Online purchasing of glasses sometimes can provide the advantage of availability of certain frame styles and/or better price.  However, it can be a confusing process and it is certainly not for everyone, especially with a complex prescription including bifocal, progressive, and or high prescription which requires precise lens measurements to ensure proper vision and comfort.  These are best measured with the actual glasses physically on a person’s face and should not be estimated.  Depending on a prescription, a slight deviation or errors in measurements can cause misalignment of optical center of the lenses and the visual axis, regardless of the accuracy of the prescription, and ultimately lead to visual discomfort and eyestrain. Choosing a pair of eyeglasses is also best done in person.  Some optical websites even provide an option of superimposing images of your selected frame and your uploaded photo to provide you with a visual image.  However, this still does not ensure the actual comfort and fitting of the glasses. Frames have different widths and temple lengths. Physically trying the eyeglasses on your face will only ascertain the comfort and the proper fitting rather than ordering a pair merely based on measurements and visual attraction -Dr. Kim   Grace M.

    I just ordered no line bifocals and i
    Am afraid the lenses are going to be thick. if i give you the prescription can you tell me how bad they will be. I have medium sized frames.

    I’m a soft 20/20 with a reading only prescription; sphere +175right / +200left, DS – cylinder. My question is that I got three pair of cheap reading glasses, +125,150,175 and 200. I took the right lens out of each pair and replaced the lower (.25) in each right eye giving me three pair of glasses with the left eye stronger that the right e.g +125right / +150 etc. Am I over simplifying this or will this work?

    • Andy says:

      Thanks for your question Archie! Some people can get by with over-the-counter reading glasses, especially with their prescription not being particularly strong. That said, it is still important to have the lenses matched to your specific PD, or Pupillary Distance. If the PD in the glasses doesn’t match your eyes, this could cause headaches as your eyes are constantly trying to adjust. Switching lenses between frames could actually make the issue worse. Your best option would be to go into a store and have them measure your PD and the PD of your frames to see if they are similar. I hope this helps! Let me know if I can help you find a store or answer any other questions. Thank you!

    I woke up with my eyelids stuck to my eyeballs. Opened them on my own & the right eye was painful & still hurts several hours later. Now I’m at work & seeing a shadow of letters on my computer screen. Could I have damaged my eye & should I see a doctor?’

    • Andy says:

      If you feel concerned about your eye or eye health, it’s always a good idea to get a doctor’s professional opinion. Could I help you find the closest America’s Best location and get you an appointment with the doctor, or do you have your own doctor that you would prefer to use?

    I recently asked the doctor at the Wal-Mart eyecenter, where I have been a customer for the last 10 years, for my most recent eyeglass prescription. She said I was -750 in my left eye. Could she have meant -7.50, or are they one and the same? Thanks.

    • Andy says:

      It’s very possible the doctor left out or forgot the decimal point, but if you’re not entirely sure the best bet is to call the doctor’s office and have them verify that for you. Thanks for your question!
