How to Determine Your Center Dominant Eye: A Complete Guide
Have you ever wondered why your aim feels off when shooting or playing sports? The answer might lie in your dominant eye. Just like being right or left-handed, most people have a center dominant eye that plays a crucial role in depth perception and accuracy. Whether you’re an archer, photographer, or just curious about how your vision works, understanding your dominant eye can improve your performance in various activities.
In this guide, we’ll explain what a center dominant eye is, how to test for it, and why it matters in sports, photography, and everyday life.
What Is a Center Dominant Eye?
Your dominant eye is the one that sends slightly more accurate visual information to your brain, helping with depth perception and focus. A center dominant eye means that when both eyes are open, your brain relies more on one eye to align objects centrally.
About 70% of people have a dominant eye that matches their dominant hand (right-handed people usually have a right-dominant eye). However, 20% have cross-dominance (e.g., right-handed but left-eye dominant), which can affect activities requiring precise aim.
Why Does Knowing Your Dominant Eye Matter?
- Improves accuracy in shooting, archery, and golf
- Enhances photography (framing shots correctly)
- Helps in eye exams (optometrists use dominance to prescribe lenses)
- Better VR and 3D viewing experiences
How to Test for Your Center Dominant Eye
Finding your dominant eye is quick and easy. Here are three simple methods:
1. The Triangle Method (Most Common)
- Extend both arms and form a small triangle with your thumbs and index fingers.
- Look at a distant object (like a clock or picture) through the triangle.
- Close one eye at a time.
- If the object stays centered when one eye is closed, that’s your dominant eye.
- If it shifts out of view, the closed eye is dominant.
2. The Point Test
- Extend one arm and point at a distant object.
- Close one eye at a time.
- If your finger stays aligned with the object, the open eye is dominant.
- If your finger appears to move, the closed eye is dominant.
3. The Hole-in-Card Test
- Cut a small hole (about 1 inch) in a piece of paper.
- Hold it at arm’s length and focus on a distant object through the hole.
- Bring the paper slowly to your face while keeping the object in view.
- The hole will naturally move toward your dominant eye.
What If You Have Cross-Dominance?
Cross-dominance (e.g., right-handed but left-eye dominant) can affect activities like shooting or baseball. Here’s how to adapt:
- Shooting Sports: Adjust your stance to align your dominant eye with the target.
- Photography: Train yourself to use the viewfinder with your dominant eye.
- Golf & Baseball: Some athletes close their non-dominant eye briefly for better focus.
Can You Change Your Dominant Eye?
While eye dominance is usually hardwired, you can train your non-dominant eye for specific tasks with practice:
- Eye patching: Covering the dominant eye forces the weaker one to compensate.
- Vision exercises: Focus drills can improve coordination.
However, completely switching dominance is rare—most people learn to adapt instead.

2. Photography
- Using your dominant eye in the viewfinder ensures better framing.
- Some cameras have adjustable viewfinders for left-eye users.
3. Golf & Baseball
- Proper alignment with your dominant eye improves swing accuracy.
- Golfers often adjust their stance based on eye dominance.
4. VR & 3D Technology
- Knowing your dominant eye helps optimize headset settings for a better experience.

FAQs About Center Dominant Eye
1. Can You Have No Dominant Eye?
Yes, some people have balanced (central) dominance, where neither eye is strongly dominant. This is rare but can be an advantage in certain sports.
2. Does Eye Dominance Change With Age?
Usually no, but conditions like cataracts or vision loss can shift dominance.
3. Can Lasik or Glasses Affect Eye Dominance?
No, but corrected vision may make your dominant eye more noticeable.
4. Is One Eye Dominance Better Than the Other?
No—it’s just a preference. However, cross-dominance may require slight adjustments in sports.
Final Thoughts: Why You Should Test Your Dominant Eye
Knowing your center dominant eye can enhance your performance in sports, photography, and even daily tasks. Whether you’re an athlete, hobbyist, or just curious about how your vision works, taking a simple dominance test can provide valuable insights.
