I tried it with my daughter which her PD is 55 tried it with the dice in fact was 55. ### ⭐⭐⭐⭐ good product *by on Reviewed in the United States May 6, 2026* this is an okay item. the measurement definitely will not be accurate if you try to do it yourself. it's best to look straight ahead and have someone else measure for you. for a quick measurement i think it's good. ### ⭐⭐⭐⭐⭐ was having trouble measuing my PD *by on Reviewed in the United States March 21, 2020* I'm very myopic, so I had a hard time measuring my PD with a rule because with my glasses off, I could not see the rule unless I was very near the mirror, and that messes up the PD measurement because you should be focusing on something far off.These solved that problem, and I ordered several pairs of glasses from Zenni, and everything has worked out nicely.Recommend.NOTE: these need a strange battery (23A) that they do not come with, so order that, too! ## Frequently Bought Together - Hanchen PD Meter Digital Pupil Distance Meter PD Ruler Pupilometer with Memory Function CE Certificate - 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) --- ## 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.pt/products/93409129-hanchen-pd-meter-digital-pupil-distance-meter-pd-ruler-pupilometer](https://www.desertcart.pt/products/93409129-hanchen-pd-meter-digital-pupil-distance-meter-pd-ruler-pupilometer) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-29*
