Have you ever wondered what all the codes on your eyeglass prescription mean? Think back to your last eye exam. Your doctor examined your vision while asking you which adjustments improved your sight. After the appointment, you received a prescription with the results, which guided your optician to create unique lenses made just for you.
While a Doctor of Optometry may use automated computerized instruments to help estimate your prescription prior to conducting a more detailed refraction, they use their extensive training and experience along with professional judgment to interpret the results. Only then can an accurate prescription be determined and customized to a patient’s visual needs.
It's a good idea to be knowledgeable about your own vision health. Take a closer look and learn what the codes mean on your prescription.
