Is the measurement accurate?** A: Yes, mine was accurate. **Q: Is it better to choose a plastic ruler or a metal ruler? How to use it?** A: I have bought both materials. I bought a metal ruler at first, but its edges are sharp. I almost hurted my child's face, so I changed a plastic pd ruler. It is transparent, measurement can be clearer and more accurate. It did not come with instruction, but I can easily get the manual video from Google. **Q: How do you use this? I need to order glasses online for myself and my children and I cannot figure this out.** A: I googled it, watched a YouTube video if I remember correctly. No instructions came with mine, so pretty annoying. ## Frequently Bought Together - Ultrassist Pupillometers for Measuring Pupillary Distance (PD) with Electronic Instruction Manual, Transparent PD Ruler, Essential Tool for Single PD or Dual PD Measurement - Ezyaid PD Ruler with Instruction Manual - Pupillary Distance Ruler for Pupil Distance Measuring, PD Measurement Tool for Prescription Eyeglasses, Include Eye Care Tips - EyeQue PDCheck Smartphone Pupillary Distance Measurement Tool - PD Measurement Tool for Eyes - Pupil Distance Measuring Tool --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/205810363-ultrassist-pupillary-distance-ruler-for-eyeglasses](https://www.desertcart.gr/products/205810363-ultrassist-pupillary-distance-ruler-for-eyeglasses) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-08*
