With the quality-designed GR-4C, you can say goodbye to time-consuming millimeter rules for measuring PDs. you and your staff will save time and enjoy more accurate prescriptions. The GR-4C uses direct point sampling to minimize errors, resulting in faster, lees variable results. With the GR-4C you will enjoy wide range measurements capabilities, digital read and LED in a lightweight device that is both accurate and consistent.
Wide Range Measurements
The GR-4C offers ease of use along with accuracy when measuring pupil distance. Now your staff can consistently measure binocular and monocular pupillary distance (PD). The measuring is an impressive 45mm to 82mm binocular to 41mm monocular.
