The peripheral vision test measures how far out to the sides you can detect visual stimuli while keeping your eyes fixed on the center. Stare at the orange dot and click when you see the flash appear at the edge of your vision.
Test Instructions
- Sit 18-24 inches from your screen
- Fix your eyes on the orange dot — don't move your eyes during the test
- Click the arena (or press Space) when you see the white flash appear
- The flash will appear at increasing distances from center

Peripheral Vision Reference
| Horizontal Range (each side) | Assessment |
|---|---|
| 90°+ per side | Excellent — full normal range |
| 70–90° per side | Good — within normal range |
| 50–70° per side | Moderate — consider an eye exam |
| < 50° per side | Limited — see an optometrist |
About Peripheral Vision
The peripheral vision test provides an informal estimate of your horizontal visual field. Professional perimetry (Humphrey Visual Field test) is the clinical standard — this test is for informational purposes only.
Why Peripheral Vision Matters
Peripheral vision is crucial for driving safety, sports performance, and fall prevention in older adults. Glaucoma typically affects peripheral vision before central vision — many people lose significant visual field before noticing symptoms. Annual eye exams include visual field checks that can catch glaucoma early.
FAQ
Is this peripheral vision test free?
Yes, completely free with no signup required. Test your peripheral vision range in your browser.
What is normal peripheral vision?
Normal horizontal peripheral vision extends about 180-200 degrees total (90-100 degrees per side). Vertical range is about 130 degrees (60 up, 70 down). This online test approximates the horizontal range using screen distance estimates. For clinical visual field testing, see an optometrist.
Can this test detect vision problems?
This is an informal screening tool, not a medical test. It can give you a rough indication of your peripheral range, but conditions like glaucoma, retinal detachment, or visual field loss require professional perimetry testing by an optometrist or ophthalmologist. Don't rely on this for diagnosis.
What causes reduced peripheral vision?
Causes include glaucoma (classic ring scotoma), retinal detachment, stroke (hemianopia), migraine aura, retinitis pigmentosa, and traumatic brain injury. If you notice sudden vision field loss or a dark spot in your peripheral vision, seek urgent medical attention.
