Eye Care EducationIs it possible for an optometrist to get your prescription wrong?

Blurry vision is less than ideal!  Your ability to see impacts your entire day. It is difficult to accomplish many tasks if you are unable to see. Is it possible for an optometrist to get your prescription wrong? Let’s explore this possibility and see!

When you go to an optometrist for an eye exam you will undergo a series of questions and lenses to look through in order to choose the best prescription. Before we even talk about the accuracy of a prescription, though, make sure that the appointment that you schedule is at a time of day that allows for your eyes to be “fresh” and not at the end of a long workday when your eyes are already tired. Your eyes use muscles, after all, to focus and be able to see. Think of it this way- you would never run 10 miles before showing up to run in a marathon! Your eyes deserve the same care and attention as other muscles in your body!


For most people, whether you have a new prescription, have never worn glasses, or are wearing a new type of glasses, adjusting to new eye prescription and glasses after an eye exam may take anywhere from a few days to 6 weeks. If after the appropriate period of adjustment, you continue to experience blurry vision, eye strain, and/ or headaches, you should consult your optometrist again.

Another thing to consider is whether the frames are shaped in such a way that they are helping your eyes. Significant changes in the shape of a lens, curve of the glass, thickness of the lens, and size of the frames can alter the way that your eyes see through your glasses which can impact not just your vision but also your peripheral vision.

If you have considered and ruled out these previous factors, it is possible that you have a prescription that is not right for you. An optometrist is interpreting your answers as well as what he or she is seeing during the eye exam. This is where the time of day and “freshness” of your eyes may impact (positively or negatively) your prescription. If your eyes were tired and straining, then you may have a skewed prescription.

Consulting your optometrist is the next step for you if after a period of up to 6 weeks you are still experiencing difficulties, such as the following:

  • Lack of focus
  • Poor vision when one eye is closed
  • Excessive eye strain
  • Headaches or dizziness
  • Vertigo or nausea, unrelated to a medical condition

Listen to your body! If you are experiencing difficulties and having significant problems, do not hesitate to contact an experienced optometrist.
