When shopping for glasses online, it’s easy to get tempted by convenience and cost. But one crucial measurement is often overlooked — Pupillary Distance (PD). This is the distance between the centers of your pupils, measured in millimeters. It may seem like a small detail, but it’s the foundation of how well your lenses align with your eyes.
When your PD is off, even by a few millimeters, the lenses may not focus correctly. This can cause blurry vision, eyestrain, headaches, and even dizziness. Unfortunately, many online glasses retailers skip or estimate this measurement, leaving customers dissatisfied.
At Enny Eye Care, we take precise PD measurements during your eye exam to ensure your prescription lenses are tailored perfectly to your eyes. That’s why in-person fittings matter — your comfort, clarity, and long-term eye health depend on it.
