The eye dominance test identifies which eye your brain favors for visual alignment. Also called the dominant eye test, it takes less than a minute using your hands and is essential for shooting sports, archery, golf, and photography aiming.

Eye Dominance Facts
| Dominance Type | Prevalence | Notes |
|---|---|---|
| Right-eye dominant | ~65–70% | Most common; favored by right-handed shooters |
| Left-eye dominant | ~25–30% | Often occurs in left-handed people; also in cross-dominant |
| Cross-dominant | ~30% of right-handers | Dominant eye opposite dominant hand; requires adjustment in shooting sports |
| No clear dominance | ~5–10% | Alternating dominance; normal variation |
How to Find Your Dominant Eye
The dominant eye test reveals which eye your visual system treats as the primary source of directional information. Unlike hand dominance, eye dominance is often unknown to people until they need it — then it becomes critical for sports accuracy and surgical planning.
The Miles Test (Most Common)
Extend both arms and form a small triangular window with your overlapping thumbs and forefingers. Look through this opening at a small, stationary distant target with both eyes open. Slowly bring your hands back toward your face while keeping the target in the window. The window will naturally migrate toward your dominant eye, which will be looking through it when your hands reach your face.
The Porta Test
Point one finger at a distant target with your arm fully extended. Keep both eyes open and the target and your fingertip aligned. Now close your left eye — does your finger stay on the target? Then close your right eye. The eye that, when open alone, keeps your finger on the target is your dominant eye. The other eye will appear to jump the finger off the target.
Practical Applications
In shooting sports, your dominant eye should be behind the sight regardless of which hand holds the firearm. If you're cross-dominant (dominant eye opposite your trigger hand), you can either close your non-dominant eye when aiming, switch your shooting shoulder, or use a blinder patch to train your dominant eye. For camera work, the dominant eye looks through the viewfinder most naturally. For monovision contact lenses (where one eye is corrected for distance and one for reading), the dominant eye receives the distance correction.
FAQ
Is this eye dominance test free?
Yes, completely free with no equipment beyond your hands. The three classic methods used — Miles, Porta, and hole-in-card — require only your fingers or a small piece of paper.
What is ocular dominance?
Ocular dominance (eye dominance) is the tendency to prefer visual input from one eye over the other. Your dominant eye doesn't necessarily see better — it's the eye your brain gives priority to when aligning and interpreting visual targets. About 65-70% of people are right-eye dominant.
Does dominant eye always match dominant hand?
Not always. About 30% of right-handed people have left-eye dominance (called cross-dominance), and vice versa. Cross-dominance is common and normal — it just has practical implications for sports like shooting, archery, and baseball batting stance.
Why does eye dominance matter for shooting sports?
When you aim a firearm, bow, or camera, your dominant eye automatically aligns the sight. If your dominant eye is opposite your dominant hand, you may need to close one eye, switch shoulders, or adopt a specific stance to shoot accurately. Many instructors recommend testing eye dominance before teaching shooting fundamentals.
Can eye dominance change?
Rarely under normal conditions. However, monovision laser surgery (LASIK/PRK), patching one eye, or significant vision loss in the dominant eye can shift dominance. Some people lack strong eye dominance (called alternating or equal dominance), which is also normal.
