Just FYI, the power switch has 3 settings: O (off), I (on), and II (I have absolutely no idea). ### ⭐ MUY MALO *by R***R on June 18, 2025* ESE PRODUCTO NO LO VOLVERIA A COMPRAR MUY MALO. ## Frequently Bought Together - Huanyu Manual Lensometer ±20D External Reading Outer Reading AC and DC Digital Lensometer Lens Meter Focimeter (AC 110V US Plug) - Huanyu Optical Digital Pupilometer 45-82mm Pupil Meter PD Meter Pupil Distance Meter Optical Instrument CE Approved (LY-9AT) - Auto Lensmeter Lensometer Focimeter, Touch Screen Optical Optometry Machine Lens Degree Meter Optical Focimeter Lensometer Measure Device --- ## 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/182699264-huanyu-manual-lensometer-20d-external-reading-outer-reading-ac-dc](https://www.desertcart.pt/products/182699264-huanyu-manual-lensometer-20d-external-reading-outer-reading-ac-dc) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-05-18*
