Peripheral Vision Test
This peripheral vision test measures how well you notice dots that flash around a central fixation point — the part of your sight that detects motion and objects outside your direct line of view. Keep your eyes on the crosshair, react when a dot appears, and the tool maps where you saw or missed each stimulus.
It is built for anyone curious about their side vision: people who want a quick self-check at home, gamers and drivers interested in awareness, or anyone monitoring changes over time. The result is a visual field map plus detection-rate and reaction-time stats you can run again whenever you like.
How to Use the Peripheral Vision Test
Configure your test
Pick a Test Eye (Both Eyes, Left Eye, or Right Eye), a Test Mode (Quick, Standard, or Thorough), and a Stimulus Duration from 200ms to 800ms. For the most accurate results, test each eye separately by covering the other.
Fix on the crosshair
After the 3-2-1 countdown, keep your eyes locked on the center crosshair (+). Resist the urge to look around — use only your peripheral vision to spot the dots.
React to each dot
White dots flash at random positions around the circle. Press Space, press Enter, or click/tap the circle the moment you detect one. Each response shows instant feedback.
Review your results
When all points are done, see your visual field map, detection rate, reaction-time stats, and a zone-by-zone breakdown. Use Test Again to repeat or New Settings to adjust the setup.
Features
Three Test Modes
Quick (24 points, ~1 min), Standard (48 points, ~2 min), or Thorough (76 points, ~3 min) to match the depth you need.
Per-Eye Selection
Test Both Eyes together or check the Left Eye and Right Eye separately to compare each visual field.
Adjustable Stimulus Duration
Choose 200ms, 400ms, 600ms, or 800ms — shorter durations make detection more challenging.
Visual Field Map
A circular map marks every detected dot in green and every missed dot in red, with concentric rings for each zone.
Detailed Stats
See your detection rate, average reaction time, fastest response, and total missed points at a glance.
Zone Breakdown
Performance is split by region — Central, Near, Mid, Far, and Outer — so you can spot where attention may be needed.
Keyboard or Tap Response
Respond with Space, Enter, or a click/tap on the circle — whatever feels fastest on your device.
Instant Feedback
Each dot shows your reaction time for a hit, a missed indicator for a miss, and a warning if you respond too early.
Frequently Asked Questions
How do you test peripheral vision at home?
Sit a comfortable distance from your screen, stare at the center crosshair, and press Space or tap the circle each time you notice a dot flash in the surrounding area — without moving your eyes. The tool tracks which positions you detected and builds a visual field map. For sharper results, cover one eye and test each side on its own.
What is a peripheral vision test called?
Clinically it is known as a visual field test or perimetry, and the in-office finger-waving version is the confrontation visual field test. This online tool is a simplified, screen-based version of the same idea: detecting stimuli across your field of vision while keeping your gaze fixed on a central point.
Can you test your own peripheral vision?
Yes, for a rough self-check you can. This test lets you screen your own side vision and compare your left and right eyes. It is a useful way to notice obvious differences or gaps, but it is not as precise as clinical perimetry, so treat it as a starting point rather than a diagnosis.
What does a peripheral vision test show?
It shows where in your visual field you reliably detect stimuli and where you miss them. The visual field map plots detected dots in green and missed dots in red, while the zone breakdown reports your detection percentage from the central area out to the outer periphery. Consistent misses in one region can be a sign worth investigating further.
Is an online peripheral vision test accurate?
It gives a useful general indication, but accuracy depends on your screen size, viewing distance, lighting, and how steadily you hold your gaze. It cannot match a calibrated clinical visual field machine. Use it for self-monitoring and trends; if you notice significant blind spots or changes, book a professional eye exam.
Which test mode should I choose?
Start with Standard mode (48 points) for a well-rounded check. Pick Quick mode (24 points) when you are short on time, or Thorough mode (76 points) when you want the most comprehensive coverage of your visual field.
What does the stimulus duration setting do?
It controls how long each white dot stays visible. A short duration (200ms) makes the test harder and better mimics quick peripheral detection, while a longer duration (800ms) is easier and good for a first attempt. The default 400ms offers a balanced difficulty.
What is a normal detection rate?
Many people with healthy vision detect roughly 85-100% of stimuli, especially in the central and near zones, with detection naturally tapering off toward the outer periphery. Consistently low detection in a specific area may warrant a professional evaluation.
