An experimental self-observation and communication tool
Visual Field Tracker is NOT intended to diagnose, screen for, monitor, treat or prevent any disease or medical condition. It has NOT been clinically validated or assessed as a medical device, and it is NOT a substitute for professional eye examination or care.
The service lets you record locations where YOU report that a visual stimulus disappears or reappears, compare user-recorded sessions and create illustrative outputs. Do NOT use its results to make medical or safety decisions.
