Pupil Distance Meter

Pupil Distance Meter is an innovative mobile application designed to measure your Pupillary Distance (PD) with clinical precision. Using augmented reality technology and a standard reference card (like a credit card), the app calculates the exact distance between your pupils - an essential measurement for properly fitted eyewear. Perfect for online glasses shopping or prescription updates, this app eliminates the need for professional equipment.

Revolutionary PD Measurement Technology at Your Fingertips

Accurate pupillary distance measurement is now available anywhere, anytime through your smartphone camera. Pupil Distance Meter transforms complex optical measurements into a simple three-step process that anyone can perform:

1. Positioning: Hold any standard-sized card (credit card, ID, or loyalty card) horizontally beneath your eyes with the magnetic strip facing outward.

2. Capture: With the app open, center your face in the frame using the on-screen alignment guides. Maintain natural posture while keeping your eyes open and looking directly forward.

3. Calculation: Our advanced computer vision algorithms instantly analyze facial geometry and card reference points to determine your precise PD measurement in millimeters.

The entire process takes under 30 seconds and delivers professional-grade accuracy comparable to optometrist measurements.

Why Precision PD Measurement Matters

Optimal Vision Correction

The distance between your pupils determines proper optical center alignment in lenses. Even slight measurement errors can cause eye strain, headaches, and blurry vision.

Eyewear Comfort

Frames with incorrect PD measurements sit improperly on your face, causing discomfort behind ears or painful pressure points on your nose.
