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.

Online Visual Field Test

Take a visual field test at home in about 5 minutes per eye. Map blind spots, track peripheral vision over time, and get plain-language AI summaries you can share with your eye doctor.

See exactly what your visual field test gives you

From a quick at-home screening to in-depth, decibel-level 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 response consistency checks, plus a plain-language AI summary describing your responses in simple terms. Works for a single eye or your full field with both eyes.

In-depth Advanced mode

Switch to Advanced mode for threshold testing that measures the sensitivity of each point in decibels. You get detailed summary metrics — an overall score, Mean Deviation (MD) and Pattern Standard Deviation (PSD) — so you can track your results in depth 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 views make gradual changes in your results easy to see and discuss with your eye care professional.

Printable PDF reports

Download a clean, printable report with a threshold map, grayscale, total deviation, probability map and global indices — organized so it's easy to review with your eye care professional. 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 Anywhere When You See a Flash

Small dots of light appear randomly around the screen. Press space or click anywhere whenever you notice a flash — even if faint. You do not need to click on the light itself.

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 hard to notice in daily life. Regular visual field screening lets you compare your results over time and gives you organized data to discuss with your eye care professional. It is not a diagnosis and does not replace a professional eye exam.

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.

Professional visual field testing is one component eye care professionals use when evaluating conditions like glaucoma, macular degeneration, and other eye or neurological concerns. This tool maps your responses so you can track them over time — it cannot diagnose any condition, so always consult an eye care professional for proper evaluation and diagnosis.

Yes. Our online visual field test runs in your browser — cover one eye, keep your gaze on the center cross, and press space or click when you see a flash. Simple mode is a quick screen; Advanced mode maps threshold sensitivity similar to clinic perimetry. It is for screening and tracking, not diagnosis.

Advanced mode uses a 24-2 style point grid and reports metrics such as Mean Deviation (MD) and Pattern Standard Deviation (PSD), but home testing on a screen is not identical to in-clinic Humphrey perimetry. Use it to monitor trends between professional exams and bring your PDF reports to your eye doctor.
