If you wear pd ruler for glasses, you may have noticed that your optometrist or ophthalmologist always asks for your “PD” or “pupillary distance” measurement. But what is PD, and why is it so important?
PD is short for pupillary distance, and it refers to the distance between your pupils (the black centers of your eyes). This measurement is important because it helps your eye care professional determine the best placement of your eyeglass lenses. If your lenses are not properly aligned, you may experience blurred vision and headaches.
There are a few particular ways to measure your PD. The most familiar method is to use a ruler. Simply hold the ruler up to your face, aligning the zero mark with the center of one pupil. Then, look straight ahead and note the number on the ruler that lines up with the center of your other pupil. This is your PD.
You can also ask a friend or family member to help you measure your PD. Have them hold a ruler next to your face, and then look straight ahead while they note the number that lines up with the center of each pupil.
A pupillary distance ruler is a device that helps you measure the distance between your pupils. This measurement is important for ordering glasses or contact lenses, as it helps ensure that you will be able to see clearly. You can purchase a pupillary distance ruler online or at most optical stores. Measuring your pupillary distance is quick and easy, and only takes a few seconds. Once you have your measurement, you can use it to order the perfect pair of PD rulers for glasses or contacts for your needs.
