The Grafton PD Meter is a digital precision optical instrument used to measure distance between pupils, pupil height and distance between glasses and eyes. 

​

• Makes high pupil measurement easier

• Detection of corneal reflection points for direct and continuous sampling

• High precision linear sensor and advanced algorithm for improved detection accuracy

• Easy to read LCD screen

• Dispersion & deformation decreased by 20%

• Soft LED light source is easy on the eye

• Automatic power off function within 2 minutes of inactivity
