How to Measure Pupillary Distance at Home: Ensuring a Perfect Fit for Your Child's Glasses
Accurate pupillary distance (PD) is essential for properly fitting glasses, especially for children. Here's a simple guide to help you measure your child's PD at home, ensuring their EyeBuddy glasses fit perfectly.
What is Pupillary Distance (PD)?
PD is the distance between the centers of your child's pupils, measured in millimeters. This measurement ensures that the lenses are correctly aligned with your child's eyes for optimal vision.
Why is PD Important?
Accurate PD ensures that the lenses provide the best possible vision correction. An incorrect PD can lead to eye strain, headaches, and blurred vision.

- Measure from the Center: Place the ruler across the bridge of the nose. Measure from the center of one pupil to the center of the other.
- Double-Check: Measure a couple of times to ensure accuracy. It helps to have another person confirm the measurement.
Tips for Accurate Measurement
- Use a Millimeter Ruler: Accuracy is key, so use a ruler with clear millimeter markings.
- Stay Still: Make sure your child remains still and looks straight ahead during the measurement.
- Good Lighting: Ensure the room is well-lit to see the pupils clearly.
