상품 특징
- 【Complete 2-in-1 Measurement Set】This package includes both a vernier caliper (21 x 5.5 cm) and a standard PVC ruler (17.7 x 2.2 cm), offering two complementary tools for pupillary distance measurement. The optical vernier provides detailed readings for professional ophthalmic use, while the PVC ruler offers quick checks at home.
- 【Precision Vernier Scale Design】This optical pd ruler features a precision vernier scale for more accurate readings than standard rulers. The sliding mechanism measures pupillary distance down to millimeter fractions, reducing common estimation errors. Clear alignment marks help identify exact scale matching points. This vernier design is especially valuable for prescription glasses, where accuracy matters.
- 【Dual-Material Construction】Crafted from PVC and PC, this pd measurement tool resists daily wear while remaining lightweight. The smooth white surface prevents scratching lenses or frames during use. These rulers maintain accuracy over time without bending under normal pressure, ensuring reliable eye measurement for optical workshops and home users alike.
- 【Precision Scales for Accuracy】The vernier caliper features clear color-coded markings that reduce measurement errors. With a range suitable for adult and child pupillary values, this optical tool allows confident readings. The PVC ruler includes millimeter markings for quick reference. Correct pd values directly impact visual comfort when ordering prescription glasses.
- 【User-Friendly Design】Both rulers require no complex calibration. The ergonomic vernier fits comfortably with curved edges preventing slip. The PVC ruler features clear numbering. Simply align with pupil centers while focusing on a distant object and read the value. This pupillary distance tool suits optometry students, optical staff, and home users.
