How to Find Your Dominant Eye at Home

Ask most golfers which eye is dominant and you'll get a shrug, or a guess based on which hand they write with. Handedness and eye dominance are unrelated traits, though, and roughly one in three right-handed golfers turns out to be left-eye dominant — a mismatch that quietly shapes how they read every line on the course.

The Triangle Test

Extend both arms in front of you and form a small triangle or gap between your thumbs and index fingers, framing a distant object — a doorknob, a light switch, anything roughly ten feet away. Keeping both eyes open, slowly pull your hands back toward your face while keeping the object centered in the gap.

The gap will naturally drift toward one eye as your hands approach your face. Whichever eye it ends up in front of is your dominant eye. Most people find the result surprisingly consistent when they repeat the test three or four times in a row.

Why This Matters Over a Golf Ball

When you set up to a shot with both eyes open, your brain still favors input from the dominant eye to judge distance and alignment. If that eye isn't positioned correctly relative to the ball and target, the picture you're working from is subtly skewed — even though both eyes are technically looking at the same scene.

Two golfers can stand over an identical setup, with an identical square clubface, and genuinely see two different aim lines.

What the Test Doesn't Tell You

The triangle test identifies which eye is dominant, but not by how much, and it doesn't measure how your specific golf posture interacts with that dominance. A golfer with strong dominance and poor posture can end up worse off than a golfer with mild dominance and excellent posture — which is why we pair the same core test with an overhead setup photo during a fitting session.

The Takeaway

Knowing your dominant eye takes thirty seconds and costs nothing. Knowing how it interacts with your actual golf setup is what turns that fact into something you can build a fitting around.
