What Does a Dominant Eye Mean?
Your dominant eye is the one your brain relies on to aim and judge direction — similar to being right- or left-handed. About two-thirds of people are right-eye dominant. It says nothing about eye health or which eye sees more sharply; it simply anchors where things are. Knowing yours matters most for photography, archery, shooting, darts, and other aiming tasks.
Find your dominant eye →What eye dominance actually is
When both eyes are open, your brain leans on one eye’s view to pin down direction and alignment — that’s your sighting-dominant eye. It’s a normal, built-in preference, not a strength or weakness. Roughly two in three people are right-eye dominant, the rest left, and a small minority show weak or mixed dominance.
Eye dominance and handedness usually match but don’t have to. Being right-handed and left-eye dominant is called cross-dominance, and it’s common.
Why it matters, and how to find yours
Anywhere you aim, your dominant eye should lead: put it to the camera viewfinder, and in archery, rifle and pistol shooting, darts, or golf putting, set your stance to the dominant-eye side. Cross-dominant shooters often learn to shoot from their eye-dominant side rather than their handed side.
The quickest way to find yours is the Miles triangle test: frame a distant object through a small triangle made with both hands, then close each eye — whichever eye keeps it framed is dominant.
