Pupillary distance is the distance in millimeters between the centers of the pupils of your eyes, which is usually not provided on prescription. Getting an accurate PD number is very important, there are free printable PD tools on the internet, but they are normally too soft (extremely bendable) and the measurement might be inaccurate, it will be very uncomfortable and harmful waring a glass that uses a wrong PD.

Wanted too buy my own sunglasses on line and the companies app could not measure my pupil distance, this little inexpensive ruler fit the bill and was extremely helpful. ### ⭐⭐⭐⭐⭐ Review *by R***E on 23 November 2025* The measurements were pretty accurate ### ⭐⭐⭐⭐⭐ Review *by G***O on 18 February 2025* The ruler is made of good material, making it durable for storage and use over many years. I found it easy to use, even without assistance from another person. I personally bought it to measure the pupillary distance of my 7-year-old daughter, and it was very simple. I also find it convenient that it offers two measurement options: the total distance between pupils and individual measurements from the center of the nose to each pupil, in case the face is not 100% symmetrical. If everyone at home wears corrective glasses, this is a must-have tool. ## Frequently Bought Together - Ezyaid PD Ruler with Instruction Manual - Pupillary Distance Ruler for Pupil Distance Measuring, PD Measurement Tool for Prescription Eyeglasses, Include Eye Care Tips - Measure Optical Vernier PD Ruler Pupil Distance Meter Eye Ophthalmic Tool (1 Pack) - EyeQue PDCheck Smartphone Pupillary Distance Measurement Tool - PD Measurement Tool for Eyes - Pupil Distance Measuring Tool --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/642937085-pd-ruler-with-instruction-manual-pupillary-distance-ruler-for-pupil](https://www.desertcart.jp/products/642937085-pd-ruler-with-instruction-manual-pupillary-distance-ruler-for-pupil) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-06-15*
