The APT (Patent Pending) is a device which combines the functionality of a pupilometer and an APD tester. Because the APT is able to measure pupils precisely and also perform a battery of APD tests (e.g., direct response, 1 second swing test, and 3 second swing test), it can be used to standardize pupil testing in your practice.

• PD and VD measurement
• Offers +2.00D compensation for the degree of eyesight
• Directness of point-sampling and high accuracy of orientation

The GR-4 uses an accuracy self-check function to minimize errors, resulting in faster, less variable results. It also features everything you need in one unit—including vertex distance measurement capabilities. The GR-4 has a wide range measurement capabilities, digital read and LED in a device that boasts a sleek, ergonomic design.
