How to measure PD

How to Measure Your Pupillary Distance (PD)

Measuring your PD at home is simple! Here's our step-by-step guide.

What you'll need:

  • A ruler (with millimeter markings)
  • A mirror

Steps:

  1. Position yourself about 8 inches from the mirror.
  2. Hold the ruler horizontally against your forehead, just above your eyes.
  3. Keep your right eye closed and align the 0mm mark of the ruler with the center of your left pupil.
  4. Keeping the ruler steady, switch eyes - open your right eye and close your left eye.
  5. The number that lines up with the center of your right pupil is your PD measurement.

For reading glasses: subtract 3mm from your measured PD when placing your order.

Pro Tips for Accurate Measurement:

  • Take multiple measurements throughout the day and use the average
  • Get assistance from a friend for better accuracy
  • When measuring, fix your gaze on a distant point (at least 20 feet away)
  • If a friend is helping, they should stand to the side to avoid interfering with your line of sight

A precise PD measurement ensures your new glasses will be perfectly aligned with your eyes!

Note: While measuring your PD at home is convenient, you can always visit an eye care professional for the most accurate measurement.

All Lenses Include:

  • 💻 Blue light blocking technology
  • ☀️ UV protection
  • ✨ Anti-reflective coating
  • 🛡️ Scratch-resistant coating

Our lenses come with all these features at no extra cost, unlike other retailers where you have to pay more for these essential features!

What Are Blue Light Blocking Lenses?

Blue light blocking lenses filter harmful blue light emitted from digital screens, helping protect your eyes and improve your sleep quality.

Key Benefits:

  • Reduced Eye Strain: Minimize discomfort during extended screen time.
  • Improved Sleep: Block blue light that disrupts melatonin production and sleep cycles.
  • Color Clarity: Virtually clear lenses avoid color distortion, unlike yellow or amber-tinted alternatives.

Is It Right for You?

If you spend hours on screens—working, gaming, or watching shows—blue light blocking lenses are ideal for reducing eye fatigue and helping you relax at night.

Note: A slight blue-tinted reflection is normal with these lenses.

Why Choose Our Lenses?

Unlike many retailers, all our lenses come with blue light blocking technology at no additional cost. It's a standard feature included to ensure your eyes are protected!

To order glasses that suit you well and match your prescription accurately, here's what you'll want:

  • A valid eyeglasses prescription from your eye care professional.
  • Your pupillary distance (PD)—if it's not on your prescription, you can measure it with a simple tool or an online guide.
  • A well-fitting pair of glasses (optional)—check the numbers on the frame's arm or bridge if you want a size reference.
Bridge measurement

PD (Pupillary Distance) is the measurement (in millimeters) between the centers of your pupils. It's crucial for aligning lenses correctly in front of your eyes.

If your prescription doesn't include a PD:

  • You might have a contact lens prescription, which often doesn't list PD since it's unnecessary for contacts.
  • Your eye doctor or optician may have left it out if they assumed you'd buy glasses directly from them. In that case, you can measure it yourself at home following a simple guide, or you can ask your eye care professional to provide it.

Glasses with prescription lenses require some extra time to custom-craft and mount. Generally:

  • Processing: Around 3–4 business days to make your lenses, fit them to the frame, and pack your order.
  • Shipping: Economy Shipping typically takes 10–20 business days (excluding weekends/holidays), while Express Shipping takes only 2–6 business days.

If you opted for non-prescription frames, they typically ship faster since no custom lens work is needed.
