Measuring your pupillary distance, or PD, is an important step in ensuring that your reading glasses fit properly for optimal vision. To accurately measure this distance, you can follow a few simple steps.
First, you will need a ruler with millimeter measurements and a mirror. Begin by standing about 8 to 12 inches away from the mirror so that you can see your face clearly. Close your right eye and look straight ahead with your left eye. Use the ruler to find the center of your left pupil and note the measurement.
Next, close your left eye and open your right eye, again looking straight ahead. Measure from the center of your right pupil to the same point on the ruler.
To calculate your PD, you will take the measurement from both eyes and add them together. This should give you a total measurement in millimeters.
Alternatively, if you prefer a more precise measurement, you may consider asking a friend to assist you. There are also online tools available that can guide you through the process.
