Completing a test is only the beginning.
Visual Field Tracker saves your measurements so that individual visual field tests can become part of a long-term visual history.
Review your visual field maps
Each saved test can contain a map for the left eye, right eye and combined visual field.
From your Test History you can reopen previous measurements, examine them in detail and add private notes about circumstances that may have affected the session, such as lighting, fatigue or the monitor you used.
You can also generate a PDF report containing your recorded results.
Repeat the test over time
A new measurement can be performed independently, or you can use an existing test as a reference for a new session.
This allows you to return to previously investigated areas and explore them again.
Your tests remain organised chronologically in your Test History, creating a timeline of your measurements.
Keep testing conditions comparable
Visual Field Tracker can optionally calibrate your screen using a standard payment card and your approximate eye-to-screen distance.
Calibration allows the application to add approximate 10°, 20°, 30° and 40° visual-angle references to your maps.
These guides can make your results easier to relate to visual field diagrams commonly used in eye care.
Calibration does not change the points you record. Its purpose is to provide a spatial reference for your saved map.
One test gives you a map. Repeated tests give you a history.
