3pcs PD Ruler For Eyeglasses - Pupillary Distance Ruler, Optician Tools

Finding your pupillary distance before ordering glasses online is simple with this 3-piece PD measurement tool for eyes. Pupillary distance, or PD, is the millimeter gap between your pupil centers, and an accurate number helps your lenses align correctly. This set includes three white PD rulers made from soft PVC, each measuring 6.96 x 0.82inch. The flexible material curves gently over the nose bridge, so the ruler stays steady while you check your PD. Clear markings make it easy to read single or dual PD values, whether you are shopping for new frames or replacing lenses in an old pair. Beyond personal use, this pupilometer measuring tool for nurses and optical staff works well in clinics, shops, and classrooms. It also serves as a spectacle frame measuring aid, letting you check frame dimensions before choosing lenses. The compact size fits in a drawer, bag, or countertop, and the 3-pack means you can keep one at home, one at work, and one as a backup. This pupillary distance ruler gives you a practical PD optician measurement scale without the cost of professional equipment. Use it as a PD ruler for eye glasses, a PD ruler for eyeglasses, or a pupillary distance ruler whenever you need a dependable reading. The soft PVC body resists bending out of shape, so the printed scale stays readable over time. Whether you are an online glasses buyer, a student learning optics, or a professional needing a spare pupillary distance measurement tool, this 3PCS PD measurement tool for eyes offers a straightforward way to measure PD at home or on the job.
