LY-9A PUPILLARY DISTANCE METER
A clear light source ensures precise measurements.
The measurement results are displayed digitally, showing separate values for the left eye and right eye.
The measuring operation is easy and rapid.
The device features an auto power-off function after completing measurements.
This pupillary distance meter allows for both monocular and binocular measurements.
Please note that this model is designed solely for testing distance pupillary distance, with its target distance set at infinity. Distance interpupillary distance refers to the distance between the centers of the pupils of both eyes when the patient is looking straight ahead at infinity.

Features of Pupillary Distance Meter
Pupil Distance Measurement
This digital PD meter accurately measures the distance between pupils. The binocular PD spans from 45 to 82 mm, while the monocular PD ranges from 22.5 to 41 mm. Use the monocular adjustment stick to facilitate testing of the monocular PD by moving it left or right.
01
Precision Alignment
Employing a mechanical hairspring, this pupilometer precisely aligns with the reflecting point on the cornea, ensuring consecutive measurements. The PD Meter Precision is adjustable, allowing you to select 0.1, 0.2, or 0.5.
02
User-Friendly Controls
Easily customize the LED lamp brightness with settings ranging from 0.5 to 5.0 in increments of 0.5. Adjust the automatic power-off time with options of 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0. Please note that batteries are not included.
03
Distance Range Adjustment
This PD meter allows adjustment of the distance range from 30 cm to ∞. A +2.00D lens under the measuring window provides visual compensation for accurate readings.
04
Versatile Applications
Easy to use and crucial in various fields, including optometry, ophthalmology, and eyewear retail. Suitable for eye care professionals such as optometrists, ophthalmologists, and opticians, as well as optical shop staff assisting customers with eyeglass fitting.
