The Humphrey 597 provides refinement of sphere, cylinder and axis for true optimization. Complete subjective testing and special targets for children and patients with reading difficulties allow the practitioner to test the widest range of patients. This unit may also be aligned in a 90 degree option depending on your office setup.
