Optical Pupil Distance Meter, Pupil Distance Detector, Measurement Range: 35cm~+∞/Accuracy: 48-77mm, Used for Measuring Pupil Distance of The Eye

Product Name: Optical Pupil Meter Measurement range: 35cm~+∞ Measurement accuracy: 48-77mm Product use: Pupil distance measurement Packing list: Optical Pupil Meter * 1 Attention: Please choose an environment with sufficient lighting. When measuring, keeping two people's eyes at the same level will make the measurement more accurate: do not move the machine during measurement, otherwise it will cause significant errors. When measuring the distance between the eyes, keep the machine stationary and check if both the left and right eyes are facing the vertical line in the field of view.
