Peripheral Vision Test

How wide is your visual field? Stare at the center and detect flashes at the edges of your vision.

How It Works

  1. Stare at the crosshair in the center of the screen — do not move your eyes
  2. Colored dots will flash briefly at various positions around the center
  3. Press SPACEBAR (or tap the screen) if you saw the flash
  4. Flashes get further from center as the test progresses
  5. Some rounds have no flash — don't press anything!
Tip: Sit at arm's length from the screen and make your browser full-screen (F11) for the most accurate results. On mobile, hold your phone at a comfortable distance.

Practice Complete!

Great — now the real test begins. Remember: keep your eyes locked on the center crosshair. 30 rounds total.

What Is the Peripheral Vision Test?

The Peripheral Vision Test is a free online visual field screening tool that measures how well you detect stimuli at the edges of your vision. You stare at a central crosshair while colored dots flash at increasing distances — from close range to the far edges of your screen. The test covers 30 rounds across 5 distance zones, plus catch trials to detect false positives. Most people score between 50-80 out of 100, with athletes and gamers often scoring higher due to trained peripheral awareness.

How It Works

The test begins with 5 practice rounds so you can learn the mechanics. You must keep your eyes locked on the center crosshair at all times — no cheating by moving your gaze. Colored dots flash briefly at random angles and distances, and you press spacebar (or tap the screen on mobile) if you detect one. Some rounds contain no flash at all, testing whether you'll false-alarm. Your score is weighted by distance zone: detecting a flash at the far edge earns more points than one near the center. False alarms deduct 5 points each.

Frequently Asked Questions

What is a peripheral vision test?

A peripheral vision test measures how well you can detect objects and movement at the edges of your visual field without moving your eyes. This online version uses flashing dots at increasing distances from a central fixation point to map your peripheral awareness across 5 distance zones.

How wide is normal peripheral vision?

Normal human peripheral vision spans roughly 200 degrees horizontally — about 100 degrees to each side. Most people can detect movement in their far periphery but have difficulty identifying fine details beyond 30-40 degrees from center. This test approximates your functional peripheral range on screen.

Can you improve your peripheral vision?

Yes, peripheral vision can be trained and improved through regular practice. Athletes, pilots, and gamers often train peripheral awareness to gain a competitive edge. Activities like sports, driving, and dedicated vision exercises can help expand your functional visual field over time.
