Understanding PD Measurements: How The Glasses Guys Make Reglazing Easy and Accurate

Crystal-Clear Vision Starts with Precision

When it comes to reglazing your glasses, one of the most important factors for ensuring visual comfort is an accurate PD measurement, which is short for pupillary distance measurement. At The Glasses Guys, we make it easy to get the precision you need—even if you don’t have your PD written down.

Whether you’re ordering single vision, bifocal, or varifocal lenses, a correct PD ensures your lenses align perfectly with your line of sight—reducing eye strain and maximising clarity.

👁️ What Is a PD Measurement and Why Does It Matter?

PD (pupillary distance) is the measurement in millimetres between the centres of your pupils. It’s crucial for ensuring your lenses are centred correctly, especially in multifocal lenses.

If your PD is incorrect, it can lead to:
👓 Eye strain
💢 Headaches or visual discomfort
🌫️ Blurred or distorted vision
🛑 Reduced lens performance

🕶️ Already Have Lenses in the Frames You’re Sending?

If you’re sending us your current glasses—and they already feel just right—great news!
Our expert technicians can take precise measurements directly from your existing lenses using professional equipment.

We’ll extract your PD and lens fitting heights from the frames you send in, meaning we can replicate your current setup with new lenses—perfectly tailored to you.

📸 Don’t Know Your PD? Just Send Us a Photo

No prescription paperwork? No problem.
If you’re ordering single vision, bifocals, or varifocals, we can calculate your PD and lens heights with remarkable accuracy—using just a photo of you wearing your glasses.

Here’s how it works:

  • You send us a photo (we’ll give you easy-to-follow instructions).

  • Our team uses advanced tools and experience to extract your PD and fitting heights.

  • You get lenses positioned with professional-grade precision, without visiting an optician.

This is ideal if your optician didn’t include PD on your prescription—or you’ve lost the details.

🧠 Why Precision Measurements Are So Important

Especially with progressive and multifocal lenses, accuracy down to the millimetre makes all the difference. Inaccurate measurements can affect how your eyes track through different vision zones—leading to fatigue, blur, or discomfort.

That’s why we’ve made it simple to share your details, however works best for you.
