What is a Visual Field Test?

A visual field test checks your peripheral (side) vision – the areas you can see without moving your eyes. When you look straight ahead, you can still notice things to your left, right, above, and below. This test measures how well you can detect objects in those areas.

Why does this matter?

Many eye conditions, especially glaucoma, damage peripheral vision first. You might not notice these changes in daily life because your brain fills in the gaps. By the time you notice vision loss, significant damage may have already occurred. Regular screening helps catch changes early.

What do the results mean?

After the test, you'll see a map showing which areas you detected lights and which you missed. Missing several points in specific patterns may indicate areas of reduced sensitivity. This is not a diagnosis – always consult an eye care professional for proper evaluation.

Visual Field Test

See exactly what your visual field test gives you

From a quick at-home screening to clinical-grade tracking — here is what you get with every visual field test, before you start.

Clear results you can actually understand

Each test produces a color-coded map of your vision — blue dots are the points you saw, orange dots are the spots you missed. You instantly get your score, test duration and reliability checks (false positives and negatives), plus a plain-language AI summary explaining what your result means and whether to follow up. Works for a single eye or your full field with both eyes.

Clinical-grade Advanced mode

Switch to Advanced mode for threshold testing that measures the exact sensitivity of each point in decibels. You get the same metrics eye doctors rely on — Visual Field Index (VFI), Mean Deviation (MD) and Pattern Standard Deviation (PSD) — so you can monitor your eyes with professional-level detail from home.

Compare any tests side by side

Line up your tests from oldest to newest and see precisely what changed. The comparison view highlights points that recovered on retest versus points that were newly missed, and calculates your overall change — so a small dip in one eye or both eyes never goes unnoticed.

Track your vision trends over time

Every result is saved automatically and charted as a vision-consistency trend for each eye. Weekly, monthly and yearly trend analysis helps you and your doctor catch gradual peripheral vision loss long before it becomes obvious in everyday life.

Doctor-ready PDF reports

Download a professional, printable report with a threshold map, grayscale, total deviation, probability map and global indices — formatted the way clinicians expect. Export a single test or a full comparison report and bring it to your next appointment in one click.

Share securely — and stay in control

Invite your doctor or a family member to view your history with secure, read-only access. Your results stay private, and you can permanently delete any test whenever you want. Your data, your eyes, your choice.

How it works

Step 1

Cover One Eye

We test each eye individually. Cover one eye completely for accurate results.

Step 2

Focus on the Center

A fixation cross appears in the middle of the screen. Keep your eyes fixed on it throughout the test.

Step 3

Click When You See a Flash

Small dots of light appear randomly around the screen. Press space or click whenever you notice a flash — even if faint.

Why Take a Visual Field Test Regularly

Glaucoma and other eye conditions can damage peripheral vision gradually — often without any noticeable symptoms. Your brain compensates by filling in gaps, making early vision loss invisible in daily life. By the time you notice changes, significant damage may have already occurred. A regular visual field test helps you spot subtle changes early and share meaningful data with your eye care professional.

Frequently Asked Questions

Our visual field test is designed as a screening and monitoring tool, not a replacement for professional diagnosis. The advanced mode uses threshold-based testing to map your peripheral vision point by point. While it does not replace a comprehensive eye exam, it helps you stay informed about your visual field health and gives you useful data to share with your eye doctor.

For monitoring purposes, taking a visual field test every 1–3 months helps track changes over time. People at higher risk for glaucoma — those with family history, age over 40, or high eye pressure — may benefit from more frequent testing. Always follow your eye doctor's recommendations.

A visual field test can reveal patterns often associated with conditions like glaucoma, macular degeneration, and other eye or neurological concerns. This tool helps you notice changes early — always consult an eye care professional for proper evaluation and diagnosis.
