• PRECISION PD MEASUREMENT - This advanced pupillary distance meter delivers highly accurate measurements with direct point-taking technology. Effortlessly measure both binocular PD (50-80mm) and monocular PD (25-40mm) with a fine 0.5mm resolution, ensuring perfect data for crafting prescription glasses.
• EFFORTLESS OPERATION - Features a direct PD adjustment lever and a separate viewing distance selecting lever for simple, rapid, and precise measurement across all kinds of viewing distances. The intuitive design makes the PD measurement process straightforward for both professionals and home users.
• ADJUSTABLE LED & VISION COMPENSATION - The energy-saving LED light design offers adjustable brightness and low power consumption, enhancing the longevity of the internal circuit board. Furthermore, this digital PD meter can compensate up to +2.0D according to the user's vision degree for greater versatility.
• SMART DATA RETENTION - Designed with an automatic shutdown function after 1 minute of inactivity to save battery life and prevent drain. It intelligently retains the last reading on the screen and stores it in memory even when powered back on, as long as the slide control remains unmoved.
• RELIABLE & CONVENIENT DESIGN - For optimal performance and automatic shut-off, store the device flat. This reliable pupil distance meter ensures your measurement data is preserved, making it a durable and user-friendly optical instrument for any optometry or personal use scenario.
