Which Eye Does Your Brain Aim With?

Dominance is a task preference, not a stronger eye.

The sighting eye is the one that preserves alignment when the other eye is closed. It often, but not always, matches the dominant hand. Some people show crossed dominance, and some do not produce one stable answer across methods.

Ocular dominance is not the same as visual acuity, eye health or the brain ignoring one eye. Normal binocular vision continues to use information from both eyes for depth, field of view and a stable scene.

Why it matters

Sighting dominance becomes noticeable in tasks that require precise alignment, such as looking through a camera viewfinder or aiming in some sports.

The result should not be used to change eyewear, cover an eye or train away a preference. Those decisions can affect binocular function and belong with qualified eye-care professionals.
