Easy to Use
It takes a tremendous amount of skill to accurately and consistently perform PDs by millimeter rule. A nasal cut for monocular PDs and a penlight to highlight the corneal reflex are all required and depend upon very good technique. On the other hand, pupillometers minimize errors, require less skill, are faster and reduce variability. The GR-4 uses an accuracy self-check function to minimize errors, resulting in faster, less variable results.
PD and Vertex
The GR-4 with Vertex Distance 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 range is an impressive 45mm to 82mm binocular and 22.5mm to 41mm monocular.
Digital Read
This easy to use corneal reflection alignment system features digital high accuracy linear sensors to provide you with precise, reliable measurements resulting in the most accurate spectacle prescriptions.
Adjustable LED
The GR-4 features LED that operators can conveniently adjust according to brightness preference.
Power-Save
With this Gilras device you can set automatic power-off time to extend battery life.
