Visual Field Test

:

Visual Field Test is an independent, browser-based perimetry tool aimed at people who want to keep an eye on their peripheral vision between professional exams. After you cover one eye and fix your gaze on a central cross, small dots of light appear at random points around the screen; you press the space bar or click whenever you notice a flash. Each session runs about five minutes per eye and produces a colour-coded map where seen points and missed points are shown separately.

The platform offers two levels of testing. Simple mode gives a fast screening pass, while Advanced mode performs threshold testing on a 24-2 style point grid and reports clinical-style summary indices including Mean Deviation (MD) and Pattern Standard Deviation (PSD). Beyond the raw map, each result is accompanied by an AI-generated summary that describes your responses in plain language, along with your score, test duration and response-consistency checks.

Results are stored automatically and charted as per-eye trend lines so gradual changes become visible over weeks, months or years. A comparison view lines your tests up from oldest to newest and flags points that recovered on retest versus newly missed points, and you can export printable PDF reports covering the threshold map, grayscale, total deviation, probability map and global indices. Read-only sharing lets a doctor or family member review your history, and any test can be permanently deleted. The site is clear that this is an educational screening and monitoring aid, not a medical device or a diagnosis.
