Description

The Rosenbaum Pocket Vision Screening Card utilizing PV Numbers™ provides 20/800 distance equivalent testing when held at a distance of 16 inches (40 cm). This card fits easily in a pocket for quick, convenient visual acuity screening. This Pocket Eye Chart is printed on durable plastic, and includes matching 20/200 Jaeger notation. Side 1 also includes pupil diameter gauge.

Side 2 features continuous text format. This format helps to simulate everyday activities such as reading. This simulation leads to better testing of the patient and helps identify near vision problems that interfere with normal activities. Side 2 includes both metric and standard rulers.
