If you are a handicraft maker and need to work frequently with eyes and hands kept at a distance of 30cm(11.8inch), you can set the distance to 30, and then measure the distance between the interpupillary distances to process glasses. It means that you can measure the interpupillary distance when the eyes look at different distances. If you need to measure the interpupillary distance between myopic eyes to equip myopia glasses, you can choose infinity. We generally default to measuring at infinity. **Q: Where is this made?** A: Made in China. **Q: Will this device measure distance pd or reading pd or an intermediate? how do you interpret the results to order progressive lenses?** A: It is the PD distance. In addition, the progressive lens has nothing to do with the interpupillary distance meter, it depends on your own needs~ Looking forward to your order. ## Frequently Bought Together - Huanyu Optical Digital Pupilometer 45-82mm Pupil Meter PD Meter Pupil Distance Meter Optical Instrument CE Approved (LY-9AT) - Hanchen Digital Display Optical Eyeglasses Frame Warmer Frame Heater Temperature Adjustable One Year Warranty (110v) - JANYUN Upgrade Version Eyeglass Repair Kit,1500 Pcs More Complete Glasses Screws Kit and Nose Pads with 6 Pcs Screwdrivers and 3 Pcs Tools for Glasses, Eyeglasses and Sunglasses Repair --- ## 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.us/products/284696618-huanyu-ce-approved-optical-digital-pd-meter-pupilometer-pupil-distance](https://www.desertcart.us/products/284696618-huanyu-ce-approved-optical-digital-pd-meter-pupilometer-pupil-distance) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-10-16*
