Peripheral Vision Test

Keep your eyes on the center. React to targets in your peripheral vision without moving your gaze.

SELECT DIFFICULTY

1

Easy

150-250px from center, 50px targets, 2000ms duration

2

Medium

250-350px from center, 40px targets, 1500ms duration

3

Hard

350-450px from center, 30px targets, 1000ms duration

HOW TO PLAY

  • Keep your eyes fixed on the center crosshair
  • Targets will appear in your peripheral vision
  • Click targets quickly without moving your gaze
  • When the crosshair changes color, press SPACE to confirm (proves you're watching the center)
  • Faster reactions and farther targets score higher
  • Game ends after 20 targets

About Peripheral Vision Test

The Peripheral Vision Test challenges your ability to detect and react to stimuli in your peripheral vision while maintaining focus on a central point. This tests both your peripheral awareness and your ability to process visual information outside your direct line of sight.

Game Features

3 Difficulty Levels
Increasing target distances from center
Fixation Verification
Crosshair changes test true peripheral use
20 Targets Per Game
Time-limited responses with scoring

Why Red Targets?

Our peripheral vision test uses red targets based on scientific research about how the human visual system works:

1
Rod Cell Sensitivity
The peripheral retina contains more rod cells, which are more sensitive to longer wavelengths (red-yellow spectrum)
2
High Contrast
Red provides maximum contrast against the beige background, making targets easier to detect without direct gaze
3
Attention Capture
Red is the most attention-grabbing color in human vision, ideal for testing rapid peripheral detection
4
Reduced Chromatic Aberration
Red light focuses more reliably in peripheral vision compared to blue light

Training Benefits

Peripheral Awareness
Improve detection of movement outside direct vision
Focus Control
Train sustained central fixation while processing peripheral stimuli

Sports Performance
Benefits activities requiring wide visual awareness (driving, ball sports, etc.)
Hazard Detection
Quickly spot potential dangers in periphery

Performance Tips

  • 1
    Keep your eyes locked on the center crosshair at all times
  • 2
    Use your peripheral vision to detect red targets - don't look directly at them
  • 3
    Stay alert for crosshair color changes and press SPACE quickly
  • 4
    Relax your eyes - peripheral detection works better when not straining
  • 5
    Click as soon as you detect motion in your periphery

Frequently Asked Questions

Q1
What is peripheral vision?
Peripheral vision is your ability to see objects and movement outside your direct line of sight. It covers approximately 170-180 degrees of your visual field and is crucial for spatial awareness.
Q2
Why does the crosshair change color?
The color change is a "fixation check" to ensure you're keeping your eyes on the center. If you're cheating by looking directly at targets, you'll miss the crosshair changes. This technique is used in clinical vision tests.
Q3
What do the difficulty levels change?
Easy: Targets appear closer to center (easier to detect). Medium: Targets appear at medium distances. Hard: Targets appear far from center (true peripheral vision). Higher difficulties test the limits of your visual field.
Q4
How is my score calculated?
Score = (Hits × 100) + (Fixation Checks Passed × 200) + Distance Bonus - (Avg Reaction Time). You earn points for hitting targets, passing fixation checks, and responding quickly. Distance from center also affects scoring.
Q5
Can this improve my real-world vision?
Yes! Regular practice can improve your peripheral awareness, which helps with sports (seeing opponents), driving (detecting hazards), and general situational awareness. It trains your brain to process peripheral stimuli more effectively.
