Product Overview:
The LY-9AT PD Meter is a high-precision digital optical instrument designed to measure the distance between human pupils (PD) during the optometry process. It is an essential tool for optometrists, eyewear retailers, and optical labs to ensure perfectly fitted spectacles for every customer.
Key Features & Benefits:
■ Ultra-Clear Optical Precision: Equipped with a precise optical structure, this PD meter delivers a sharp, crystal-clear line of light for accurate measurements. The results are displayed digitally, with separate readings for the left and right eye, ensuring no guesswork.
■ Effortless & Fast Operation: The simple, rapid measuring process is complemented by a free-moving direct PD adjustment lever. Combined with the adjustable viewing distance selector, you can easily measure at any distance (from 30cm to infinity) for both near and far vision, making every measurement simple and precise.
■ Smart Power & Memory Features: After each measurement, the auto power-off function conserves battery life, while the built-in memory function securely stores your last reading—so you never lose important data during a busy day.
■ Versatile Monocular Measurement: In addition to binocular PD, this device also supports Monocular measurement, allowing you to measure the left and right eyes separately for patients with asymmetric PDs or special fitting needs.
